This Bald Eagle (Haliaeetus leucocephalus) looked a bit bedraggled when I spotted it on Tuesday at Occoquan Bay National Wildlife Refuge, where it was perched just above the large eagle nest in which a young eagle was visible. Harried parent? Check out yesterday’s posting “Looking out of the nest” if you missed the photos of the inquisitive juvenile eagle.

The sky was totally overcast on the day when I took these photos and the sky was almost pure white. The resulting effect makes these shots look almost like high key portraits taken in a studio setting, although personally I would have liked a little more directed light to make the photos look less flat. Still, any day is a good day when I get to see a bald eagle.

It was really cool on Tuesday to be able to capture these images of a young Bald Eagle (Haliaeetus leucocephalus) looking out from the large eagle nest at Occoquan Bay National Wildlife Refuge. The growing eaglet appeared to be quite alert and was sitting up quite high near the edge of the nest. I love how you can see the mottled plumage, dark eyes, and multi-colored beak of this eaglet in these photos.

The nest is high in the trees and there is now a lot of vegetation growing, so it was quite a challenge to get a clear angle of view. I am pretty happy with the results that I was able to achieve. The eaglet looks to be big enough to be flying, but I am not sure if that is the case. One of its parents was perched on some branches just above the nest, so I am pretty sure that it is not yet ready to go out on its own—eagles normally take about 12 weeks to fledge and then may hang around with their parents for another month or two.

I have seen an Indigo Bunting (Passerina cyanea) only a few times in my life, so I was thrilled last week when I spotted one last week at Occoquan Bay National Wildlife Refuge, my second sighting of this species this year. Once again I was struck by the brilliant blue coloration of its feathers—even from a distance the bird’s amazing blue color really stood out.

As I was doing a little research, I was surprised to learn that Indigo Buntings, along with other buntings and grosbeaks, are part of the Cardinalidae family, which I tend to associate with the bright red Northern Cardinals. When I look at the first photo, though, I must admit that the raised crest on the head of the bunting does remind me a bit of a cardinal.

I did not notice it when I took the first photo, but as I was processing the first image I spotted what appears to be a band on the bird’s right leg—I encourage you to click on the image to get a closer look at that leg. There is a bird banding station at this wildlife refuge and several years ago I visited it and watched the fascinating process of bird banding (see my 2018 posting entitled Visit to a banding station). I recall being amazed at the range of sizes of the bands, which allow for the banding of birds even smaller than the Indigo Bunting, which is about 5 inches (13 cm) in length.

I believe that Indigo Buntings remain with us all summer, so I will be keeping my eyes open for them during future visits. However, I couldn’t help but notice how the trees are now covered with leaves and the vegetation is lush, which makes it really hard for me to see small birds, even when I am able to hear them.

On Saturday I spotted my first Spangled Skimmer dragonflies (Libellula cyanea) of the year at Occoquan Bay National Wildlife Refuge. It is remarkable easy to identify this species, because it is the only dragonfly in our area that has both black and white stigmata.

The stigmata, or pterostigmata, which is the more technical name, are the pigmented hollow structures on the leading edge of dragonfly wings. They are slightly heavier than the adjoining cells and have a significant effect on the aerodynamics of the wing, particularly while gliding, according to an article entitled “Dragonfly wings: tried and tested over millennia!” I confess that I don’t understand aerodynamics at all and look at dragonfly flight as nothing short of miraculous.

You may have noted that all the dragonflies in all three photos look pretty much the same, but the first two are male and the third is a female. Mature males are blue in color, but when they are young, the immature males share the brown and yellow coloration of the females. The easiest way to tell them apart is to look at the tip of the abdomen (the “tail”)—the terminal appendages of the two genders are quite different in appearance.

When the Horned Grebe (Podiceps auritus) emerged from the water on Monday at Occoquan Bay National Wildlife Refuge, I initially thought that he had snagged some underwater vegetation. However, it quickly became apparent that the prey was wriggling and squirming and was in fact alive. It looked a bit like a small snake or maybe some kind of marine worm, but several Facebook viewers later informed me that it was probably an American Eel (Anguilla rostrata).

The eel put up quite a struggle, but I believe that the grebe eventually subdued it and swallowed it. Unfortunately the grebe turned his back to me during the process, so I was not able to document the final phases of his efforts with my camera.

I was a bit surprised and absolutely delighted to see my first Monarch butterfly (Danaus plexippus) of the year yesterday at Occoquan Bay National Wildlife Refuge. I love to see these colorful butterflies, but each year it is a bit of a hit-or-miss proposition, as habitats for Monarchs continue to be threatened and their numbers seem to be declining.

I spotted this Spotted Sandpiper (Actitis macularius) on Monday at Occoquan Bay National Wildlife Refuge. There are a lot of sandpipers that are similar in appearance, so I was not sure what kind it was when I took these shots. As I looked through my bird identification guide, however, I realized that the spots on the bird’s chest and the orange bill made it quite easy to identify, because these traits are distinctive for breeding Spotted Sandpipers.

I was intrigued to learn on the Cornell Lab of Ornithology website that the female Spotted Sandpiper is the one who establishes and defends the territory—she arrives at the breeding grounds earlier than the male, unlike in other species of migratory birds, where the male establishes the territory and arrives earlier. More amazingly, the male of this species takes the primary role in parental care, incubating the eggs and taking care of the young. Wow!

I am finally starting to see many of the common species of dragonflies and damselflies that will keep me company through the long hot days of the summer. On Monday at Occoquan Bay National Wildlife Refuge I spotted my first Big Bluet damselflies (Enallagma durum) of the season, including the mating pair shown in the first photo below. This sidewards heart position, sometimes referred to as the “wheel position,” is quite distinctive and reminds me of something you might see in a Cirque du Soleil production.

American bluets are the largest genus of damselflies in North America and are often the most familiar and numerous damselflies that people see. As the genus name Bluet suggests, most members of this genus have bright blue coloration in various patterns, although I have also photographed Orange Bluets, which sounds like a contradiction in terms.

During the summer, I often see Big Bluets along the trails adjacent to the water at this wildlife refuge. As damselflies go, Big Bluets are comparatively large at 1.3- 1.7 inches (34 – 44 mm) in length. Big Bluets have elongated, arrow-shaped black markings on their abdomens, as  you can see in the second photo below, and this helps in distinguishing them from other bluets.

Damselfly identification is challenging under the best of all circumstances and even in this case, when I was fairly confident about my identification, I sought confirmation in a Facebook dragonfly group.

I was tracking the movement of this colorful Prothonotary Warbler on Monday (Protonotaria citrea) at Occoquan Bay National Wildlife Refuge as it hopped about in the dense green foliage, when suddenly it popped into the open and I was able to capture these images.

I absolutely love the bright yellow coloration of this warbler that never fails to put a smile on my face—years ago I used to drive a Toyota Matrix that was Solar Yellow and was visible from a long distance away. It was cool during this encounter that the bird was close enough to me that I managed to capture the reflection of the sky and the landscape in its eye.

I was excited to spot this juvenile Bald Eagle (Haliaeetus leucocephalus) sitting up in the big nest at Occoquan Bay National Wildlife Refuge on Monday. I assume that this eaglet was born this spring, based on its coloration and markings.

Earlier this spring I had noted eagle activity around this nest and thought that the nesting process had already begun long ago. However, this nest is very large and so high up that it is impossible to tell when the eagles began to sit on the egg or eggs. I checked my blog postings from the past and saw that I posted a shot of eaglets at this same nest on 19 May last year (see the posting Eagle nest update in May), so things seem to be following the same approximate schedule.

I saw only a single eaglet this time, but will continue to monitor the nest for more eaglet activity, including indications that there is more than one eaglet. Earlier on the same day I spotted an adult eagle perched in a tulip tree—you can actually see some of the “tulips”— adjacent to the nest and suspect that this is one of the parents keeping an eye on the eaglet(s). I included a shot below of the presumed proud parent as a final photo.

This bird was in the middle of a field on Tuesday at Occoquan Bay National Wildlife Refuge when its movement caught my eye. When it hopped to the top of the vegetation, its brilliant yellow chest made it really hard to miss, even though it was far away. I am pretty sure that it is a Yellow-breasted Chat (Icteria virens), my first sighting ever of this cool bird species.

Many of the migrating warblers that are passing through my area have various yellow markings, so I assumed that this was simply another warbler that I had never seen before. The reality, however, is hardly simple. According to Wikipedia, “The Yellow-breasted Chat (Icteria virens) is a large songbird found in North America, and is the only member of the family Icteriidae. It was once a member of the New World warbler family, but in 2017, the American Ornithological Society moved it to its own family. Its placement is not definitely resolved.”

Compared with most other warblers, the Yellow-breasted Chat seems much larger and bulkier and it has a relatively long tail and a rather robust beak. I love the bright yellow color on its breast and the distinctive eye-markings that make it look like the bird is wearing spectacles.

I think that we are nearing the end of the period of bird migration, but I will definitely keep my eyes open for possible new finds like this gorgeous Yellow-breasted Chat.

Although I have photographed a Horned Grebe (Podiceps auritus) several times in the past, I had never seen one in colorful breeding plumage until yesterday. According to the range maps on the Cornell Lab of Ornithology website, Horned Grebes do not breed in my area, so this one, who was swimming by himself, may just be passing through as he migrates northward.

The colors and patterns on this bird are amazing. The gold circles in the grebe’s red eyes really grab a viewer’s attention, though I must admit that I find them to be a little bit creepy—it is definitely worthwhile to click on the photos to get a closer look at those eyes. The bird’s distinctive “horns” appear to be tufts of long golden feathers behind each eye in a pattern that is reminiscent of the haircut of a medieval monk, particularly in the middle photo. My favorite photo may well be the final one that captures some of the grebe’s spunky personality.

Like most other grebes, Horned Grebes have compact bodies, relatively short necks, blocky heads and straight, narrow bill that is very different from a duck’s bill. I observed the grebe as it repeatedly made short dives in search of food yesterday in the waters off of Occoquan Bay National Wildlife Refuge. According to the Cornell Lab of Ornithology, during the breeding period Horned Grebes also feed heavily on insects and larvae, some caught in the air, others in or on the water.

Although I enjoy photographing large, colorful butterflies, like the Zebra Swallowtail that I featured in a recent posting, I also love to photograph smaller, more nondescript butterflies. I spotted this pretty little Silver-spotted Skipper (Epargyreus clarus) during a visit to Occoquan Bay National Wildlife Refuge and chased it about as it gathered nectar from several early spring wildflowers.

There are over 3500 species of skipper butterflies worldwide, according to Wikipedia, and the Silver-spotted Skipper is one of the few that I can reliably identify. Many of the others that I see are so similar in appearance that I have to pore over identification guides to try to figure out what kind they are. Often I end up guessing and am wrong just about as often as I am right in identifying a skipper.

I was thrilled to capture this image of an Eastern Comma butterfly (Polygonia comma) during a recent visit to Occoquan Bay National Wildlife Refuge. When its wings are closed, this butterfly blends right in with the bark of the trees on which it frequently perches, so it was nice that it chose to perch on some green leaves.

Zebra Swallowtail butterflies (Eurytides marcellus) are amazingly skittish. They fly all about, approaching plants as though they were planning to land and then change course at the last moment. I was thrilled during a recent trip to Occoquan Bay National Wildlife Refuge when this beautiful Zebra Swallowtail landed on a small wildflower and stayed still long enough for me to lower my monopod and focus on it.

I was shooting at the extreme end of my long telephoto zoom lens and was not sure if I could capture the fine details of the butterfly—the lens is supposedly soft at 600 mm. I was delighted when I saw my shots on my computer to see that I had managed to capture the beautiful red markings that really pop amid the zebra stripes pop on this swallowtail. Even the long antennae and the “tails” of the butterfly are pretty sharp.

Every year I challenge myself by attempting to capture images of dragonflies in flight. Some dragonfly species help out by flying in somewhat predictable patterns or by hovering a bit, but it is still pretty tough to capture a tiny moving subject like a dragonfly.

This week I managed to photograph Common Baskettail dragonflies (Epitheca cynosura) in flight on two consecutive days at different locations using different lenses and techniques. Male Common Baskettails often patrol around the edges of small ponds in fairly limited areas. If you observe them long enough, you can get a general sense of the track that they are following.

For the first photo, I extended my Tamron 150-600mm lens to its maximum length and pre-focused on an open area that appeared to be part of the patrol route at a small pond at Occoquan Bay National Wildlife Refuge. My camera was on a monopod and when the dragonfly entered the target area, I would attempt to track it and focus the lens manually. It sounds pretty straightforward, but the hand-to-eye coordination required makes this approach quite daunting. However, as you can see in the first photo, it is possible to get a decent shot. If you click on the image, you can see lots of cool details, including the way that the dragonfly has folded up its legs under its thorax.

The next day I was exploring a small pond in Prince William County when I spotted a patrolling dragonfly—it was another male Common Baskettail. I had my Tamron 180mm macro lens on my camera and was not using a monopod. I was able to track the dragonfly a bit more freely with this lighter lens, which proved to be beneficial when the dragonfly deviated from its flight path. Once again I focused manually and was thrilled with the results I got in the second and third images below. I particularly like the way that I was able to capture some of the pond environment in the second shot, while managing to get the dragonfly in sharp focus.

Why do I use manual focus? My Canon 50D is a long in the tooth and has a relatively primitive focusing system with only nine focus points, which means that my camera can’t focus fast enough or accurately enough to shoot a dragonfly in mid-air. More modern camera have much faster and more sophisticated focusing systems and theoretically can produce better results. I saw a video recently, for example, in which a photographer was able to use animal eye focus on a moving dragonfly. Yikes! You pay a real premium, though, for that advanced technology, with camera bodies costing up to $5,000 and lenses up to $12,000.

I am not all that impressed by fancy camera gear and would rather focus on mastering the more modest gear that I have and spending as much time as I can out in the wild. In my mind, that recipe sets me up best to take advantage of the opportunities that arise as I wander about in nature.

I kept hearing loud singing coming from the top of the trees on Monday at Occoquan Bay National Wildlife Refuge, but had trouble locating the source of the singing. Leaves are now covering the trees, complicating my efforts to spot small songbirds. Eventually I managed to locate the birds and they turned out to be Indigo Buntings (Passerina cyanea).

Once again I was amazed by the deep blue coloration of the male Indigo Buntings—its intensity never fails to startle me. The bold color of the Indigo Buntings, sometimes nicknamed “blue canaries,” was matched by the cheerfulness of their songs. According to the Cornell Lab of Ornithology, “Male Indigo Buntings whistle a bright, lively song of sharp, clear, high-pitched notes that lasts about 2 seconds. They are voluble, singing as many as 200 songs per hour at dawn and keeping up a pace of about one per minute for the rest of the day.” Check out this link to hear samples of some of the songs of Indigo Buntings.

I was amazed to discover about how Indigo Buntings learn to sing. According the Cornell Lab of Ornithology, “Indigo Buntings learn their songs as youngsters, from nearby males but not from their fathers. Buntings a few hundred yards apart generally sing different songs, while those in the same “song neighborhood” share nearly identical songs. A local song may persist up to 20 years, gradually changing as new singers add novel variations.” Wow!

I believe that Indigo Buntings will be with us all summer and I hope to get some shots at closer range. I have fond memories of the first time I photographed a male Indigo Bunting in August 2017 as he perched on the drooping head of a sunflower—check out the posting entitled Indigo Bunting and Monarch.

On Monday I spotted my first Green Heron (Butorides virescens) of the season at Occoquan Bay National Wildlife Refuge. Unlike Great Blue Herons that remain with us all winter, Green Herons migrate to warmer places in the fall and return to our area in the spring and spend the summers with us.

When I first spotted the heron, it was perched in a tree, as shown in the final photo. I passed by the heron, stopped a short distance away, and waited. Eventually the heron grew comfortable with my presence (or chose to ignore me) and hopped down out of the tree. Recent heavy rains had caused a pond to overflow onto a road and I was happy to be able to get some shots as the heron poked about in the shallow waters at the edge of the road.

I crouched as low as I could and waited for the heron to move into one of the patches of light. The little moved slowly and deliberately, gradually Green moving into the dense undergrowth where I had trouble tracking it. It was a cool encounter with one of my favorite birds—in my experience Green Herons show a lot of personality than other herons.

Green Herons are also one of the world’s few tool-using bird species. According to the Cornell Lab of Ornithology, Green Herons “often create fishing lures with bread crusts, insects, and feathers, dropping them on the surface of the water to entice small fish.” I have not yet seen this kind of behavior, but try to be particularly alert whenever I spot a Green Heron. It would be easier for me to recognize the behavior if the Green Heron used something more distinctive, like a little fishing pole.

I was absolutely delighted yesterday to spot several colorful Calico Pennant dragonflies (Celithemis elisa) while I was exploring a pond at Occoquan Bay National Wildlife Refuge. There is something really special about dragonflies with patterns on their wings, and Calico Pennants have wonderfully intricate patterns on their wings, particularly on their hind wings.

Yesterday was our first sunny day in a week or so and the weekend had been unseasonably cold, so it felt especially good to be outdoors again. It is still early in the season for many dragonflies species, but I try to be diligent in searching areas where they might be present. Some days, like last Friday when I spotted the Lady’s Slipper orchids that I featured yesterday, I am not able to find any dragonflies at all, while other days my persistence pays off—that is the fate of a wildlife photographer.

I spotted this Common Green Darner dragonfly (Anax junius) during a recent trip to Occoquan Bay National Wildlife Refuge. It was patrolling overhead within a fairly confined area and I was able to track it visually until it finally landed. The photo makes it look like the dragonfly was climbing its way out of a deep pit. In reality, however, it was hanging from some roots sticking out from a big pile of dirt.

I was a little surprised that I was able to capture as much detail as I did, given that I was shooting with my Tamron 150-600mm lens fully extended to 600mm. Supposedly the lens is soft at 600mm, but good stabilization techniques (including using a monopod) and a little tweaking with software produce images that are acceptably sharp to my eyes.

I love the multi-colored bodies of Common Green Darners, one of the largest dragonflies in our area with a body length of about 3 inches (76 mm). I think that this is a male. Mature males normally have bright blue abdomens, but they may turn purple when temperatures are low, which seemed to be the case when I took this photo. Females, by contrast, have abdomens that tend to be a mixture of tan and gray-green. For both genders, the thorax (the “chest” area) is bright green.

If you click on the image, you can get a better look at the dragonfly’s “bullseye” marking, the black and blue dot that is found on the “nose” of both male and female Common Green Darners. I am always thrilled when I manage to get a shot that captures the bullseye so well.

We are in the midst of a spell of cool, rainy weather so I have not seen any dragonflies in over a week. The weather is forecasted to warm up a bit, so I am hoping that I will have better success in the upcoming week.

Most warblers forage in the forest canopy and I have to strain my neck to search for them. Palm Warblers (Setophaga palmarum), however, mainly forage on open ground or in low vegetation.  When I saw a flash of yellow in some low bushes last week at Occoquan Bay National Wildlife Refuge, I therefore suspected that it might be a Palm Warbler.

I watched and waited and eventually the bird hopped up onto a branch and I managed to get a clear shot of it. I wasn’t one hundred percent sure that it was a Palm Warbler, but the color and markings looked about right and I could see the rust-colored cap on its head, another identification feature for a Pine Warbler. Some experts in a Facebook forum confirmed that “my” bird is indeed  a Palm Warbler.

The warblers are with us for only a limited period of time in the spring before they continue their migration northward, so I don’t know how many more times I will have a chance to photograph them. At this time of the year, though, colorful flowers are popping up and insects are reappearing, so I won’t suffer from a lack of subjects when the wablers depart.

I spotted this colorful Prairie Warbler (Setophaga discolor) as it was singing high in a tree on Thursday at Occoquan Bay National Wildlife Refuge. Most of the time I spot birds like this when they fly to a new perch, but this warbler stubbornly refused to move. I stared and stared at the tree, desperately trying to locate the source of the song that the bird was singing over and over again.

I finally located the warbler in the crook of a branch. I was looking upward at such an acute angle that I mostly got a view of the underside of the bird, but eventually I captured the first image in which the warbler was singing. Prairie Warblers have an unusual rising song that the Cornell Lab of Ornithology described in these words, “The Prairie Warbler sings a distinctive, rising and accelerating song with a buzzy quality, zee-zee-zee-zee-zee-zeeeee.” If you click on this link, you can listen to several sound samples of the songs of the Prairie Warbler.

I do not know how much longer the migratory warblers will be in my area, but I hope to have another chance to see some of these joyous little birds. I am still not confident in my identification skills for warblers, so there is a chance that I am wrong about this being a Prairie Warbler, but its beauty is undeniable.

I was delighted yesterday to spot this beautiful Black Swallowtail butterfly (Papilio polyxenes) at Occoquan Bay National Wildlife Refuge, the first one that I have seen this season. At this time of the year I am always struck by the pristine look of the newly emerged butterflies—later in the season they will become tattered and faded.

In my area we have four different black swallowtails—the Black Swallowtail, the Spicebush Swallowtail, the Pipevine Swallowtail, and the dark morph female Eastern Tiger Swallowtail. Sometimes it can be difficult to distinguish between the species, but in this case it was really easy. Male and female Black Swallowtails can be identified by the black dot inside the orange dot in the middle of the bottom of the hind wings, as you can see in this photo. Several years ago I came across a wonderful posting by the Louisiana Naturalist that has side-by-side comparisons of these four species and tips on how to tell them apart.

Last Friday, Jet Eliot, a wonderful writer and blogger who lives on the West Coast, wrote a fascinating blog posting entitled Swallowtail Butterflies that looked at some of the swallowtails in her area as well as others that she has encountered during her worldwide travels. The photos in the posting by Athena Alexander are astounding and Jet’s prose is informative and inspiring. I encourage you to check out the posting and leave you with this wonderful snippet from Jet—”I am often buoyed by these dancing kaleidoscopic creatures who start out so immobile and teensy and dark, and as each day turns to the next, they somehow know what to do. Soon they have mysteriously blossomed into delicate splendor.”

Have a wonderful weekend.

Quite often the simplest of subjects can be incredibly beautiful, like these little white butterflies that I photographed last week. Many folks might dismiss these nondescript creatures as moths or simply ignore them. It really is worthwhile to slow down and look at them closely.

The butterfly in the first photo is a Cabbage White (Pieris rapae) that was feeding on a patch of what I believe is purple dead nettle. Although it looks like a macro shot, I captured the image at the 600mm end of my telephoto zoom lens.

I took the next two pictures with an actual macro lens, my trusty Tamron 180mm lens. The tiny Eastern Tailed-Blue butterfly (Cupido comyntas) has a wingspan of about an inch (25 mm) and I was thrilled to capture so much detail of its beauty, including the little “tails.”

Beauty is everywhere.

I could hear a bird singing in a tree on Wednesday at Occoquan Bay National Wildlife Refuge, but I had trouble finding it. Eventually I spotted some movement and was able to track the bird, but it remained mostly hidden. I saw some flashes of yellow and assumed that it was some sort of warbler. I finally managed to get decent shot of it and was anxious to check out my birding guide to see what it was.

When I looked through the warbler section of the book, none of the images seemed to match “my bird.” What else could it be? Suddenly I remembered that a couple of other local photographers had mentioned seeing vireo at this refuge. Could this be a vireo?

The overall coloration and the stunning eye convinced me that this is almost certainly a White-eyed Vireo (Vireo griseus), a new species for me. This is definitely one of the coolest looking birds that I have seen in a long time. I love the wash of pale yellow on its breast and the darker yellow around its bill. If you click on the image and look carefully at the bill, you will see that it is slightly hooked, which is not the case with warblers.

I went to the Cornell Lab of Ornithology website to learn a bit more about the behavior of this species—”White-eyed Vireos hop among branches and make short flights between shrubs, making sure to stay well hidden in the process. Males sing from the edges of understory vegetation all day long, even during the heat of the day.” I still have trouble geolocating a bird on the basis of sound, but can use all the help I can get.

I am currently alternating between looking for birds and looking for dragonflies. At this time of the year, they are found in vastly different habitats, so I have to make a decision when I set out in my car. I am absolutely thrilled that I have already had some success with both birds and dragonflies this spring and look forward to new discoveries.

Yesterday I featured a warbler that was so brightly colored that it was impossible to miss. Today’s warbler is the complete opposite—it was so nondescript and so well hidden that it was almost impossible to see and initially I could not even identify it from my photos.

My eyes detected some motion high in a pine tree on Wednesday at Occoquan Bay National Wildlife Refuge and I stopped. I had set my long lens on a monopod, so my arms did not get tired as I strained to make out the bird that was moving about among the pine needles and the pine cones, though my neck quickly became sore. It looked like the bird was feeding on little seeds, so it would stop momentarily from time to time, giving me a change to find it in my viewfinder and acquire focus.

None of my shots was spectacular, but I was able to capture enough details of the bird’s body that some experts in a Facebook birding group identified it as a Pine Warbler (Setophaga pinus). Not only were they able to identify the species of the bird, they determined that it was a first year female on the basis of its markings and coloration. I am always amazed when confronted with that level of expertise.

Yesterday I set aside my macro lens and put my telephoto zoom lens back on my camera.  Over the past week, I have seen some amazing photos by local photographers of a variety of colorful warblers that migrate through our area in the spring and the fall and I felt compelled to try to photograph them. I must confess, though, that I have never had much success photographing warblers. I can often hear these little birds, but have trouble locating them in the tops of the trees—they seem to be teasing me as they flit about and sing their songs.

I walked around a lot and eventually had several encounters with Prothonotary Warblers (Protonotaria citrea) at Occoquan Bay National Wildlife Refuge. Some warblers have markings and colors that allow them to be camouflaged in the foliage, but the plumage of a Prothonotary Warbler is such a bright yellow that it is impossible for one to hide.

These warblers never seem to sit still for very long and they move quickly from branch to branch. I was happy that I was able to track them reasonably well, considering that I had my zoom lens extended to its maximum length. It takes some practice to be able to see something with your eye and then be able to point the lens in the proper direction.

I exceeded my expectations in getting these shots and also managed to photograph several other bird species that I will probably be featuring in future postings. Today I will probably switch back to my macro lens and focus again on insects. The transitional seasons definitely keep me busy as I try to keep an eye on close-in subjects and those that are farther away.

I was happy to spot several Blue Corporal dragonflies (Ladona deplanata) on Wednesday at Occoquan Bay National Wildlife Refuge, my first dragonflies of the year at that location. Blue Corporals almost always perch low to the ground, which makes them a challenge to photograph, as you can see in these photos.

In our area, Blue Corporals are found most often in the coastal plain region, unlike the Uhler’s Sundragon that I featured in an earlier posting (First dragonfly of 2022) that is found at rocky forest streams. Most of the early spring dragonflies are found in specific and limited habitats, while many of the summer species can thrive in a variety of habitats.

You may have noticed that none of these Blue Corporals are blue. Adult males are bluish in color and both the male and the female have two white stripes on their thoraxes in an area that you might think of as their shoulders. In the military of the United States, the rank insignia for corporals is two stripes, which accounts for that portion of the common name for the species.

When males first emerge, however, they share the same tan coloration as the females and as they mature they turn blue. (Here’s a link to a 2018 posting called A Bluer Corporal that shows a mature male.) The dragonfly in the final photo looks to be an immature and the one in the middle photo is a female—the angle of the first photo makes it hard for me to determine its gender.

It is still really early in the dragonfly season, so I am excited every single time that I spot one. Actually my enthusiasm for dragonflies barely wanes as we get deeper into the season and the early dragonflies give way to new species.

Ospreys (Pandion haliaetus) were really vocal and active last week at Occoquan Bay National Wildlife Refuge.  Most often, though, the ospreys were flying out of range of my lenses, so getting shots of them was a bit of a challenge.

Eventually I manage to get a shot of some  perched ospreys. In the first and third photos, the osprey appeared to have a fish that it kept hidden from me. Perhaps it had had a recent experience with an eagle trying to steal its catch and consequently was hyper-possessive now. I think that attitude also explains why the bird was in a defensive, crouched position and would look around before taking a bite of the unseen fish.

The middle photo shows an osprey on a nest that is being constructed on a channel marker in the waters off of the wildlife refuge. In the past,I have photographed much larger nests on this same buoy—check out my blog posting entitle Defying gravity from last year to see a photo of a previous iteration of a nest at this spot.

In the last few days some local photographers have posted photos of warblers at this wildlife refuge, so I will be looking for small birds as well as the larger, more visible ones like these ospreys. Insect activity is beginning to pick up too, so it looks like April will be a busy time for me and my camera.

I love seeing the differences between juvenile and adult Bald Eagles—the coloration and markings of the eagles change dramatically over time. Earlier this week I did a posting called Two eagles that showed two juvenile eagles perched in a tree. One of them was quite young and the other was almost an adult. It was really easy to see the differences between the two stages of development, with only the older one showing the distinctive white head feathers.

Today I am featuring in-flight photos of two eagles that I spotted last Monday while exploring Occoquan Bay National Wildlife Refuge. The first photo shows a juvenile Bald Eagle that looks to be about two to three years old. The head appears to be dark and the there is a mottled mixture of white and brown feathers. The second image shows a mature Bald Eagle with a white head and uniformly dark feathers.

It is an awesome experience for me when eagles fly almost directly over me and I love trying to get shots of them. I never fail to be impressed by their amazing wingspans, which can reach more than seven feet (213 cm).

Most of the times when I photograph an Osprey (Pandion haliaetus), the bird appears to be long and lanky. The angle at which I photographed this osprey, however, distorted its proportions, making it seem more short and squat than normal. The spherical head and the osprey’s exaggerated expression of curiosity and surprise help to make this image feel comical and cartoonish—I can’t help but smile every time that I look at the photo.

There are quite a few ospreys now at Occoquan Bay National Wildlife Refuge and quite soon they will be working on their nests. I hope to be able to capture some shots of that activity. Now that we have moved into April, I will start to switch some of my focus to searching for dragonflies. With a bit of luck, I will see my first dragonflies of the year with a week or two.
