It is a little unusual for me to post photos of the same species twice within a few days, but I could not help myself when I captured this image of a female Swamp Darner (Epiaeschna heros) that provides such a wonderful view of her remarkable eyes.

Dragonfly eyes are always amazing, with their multiple lens that give the dragonfly almost 360 degree vision and the ability to see parts of the color spectrum that are invisible to the human eye. What is particularly striking about this Swamp Darner’s eyes are its varied colors and patterns. Wow!

The second image shows the same female Swamp Darner as she rested in a tree prior to beginning the task of depositing her eggs, which is what you see her doing in the first shot. I captured these images this past Tuesday during a visit to Patuxent Research Refuge in Laurel, Maryland.

Do you like a fun photo challenge? Try taking a photo of a dragonfly as it zooms on by you.

Here’s an image I captured on Tuesday of a Common Baskettail dragonfly (Epitheca cynosura) in flight at Patuxent Research Refuge in Laurel, Maryland. In case you are curious, Common Baskettails are about 1.6 inches in length (41 mm).

So how would you go about getting a shot like this? I would say that the key requirements are patience and persistence. The first thing that I usually do is observe the dragonfly’s flight path and try to determine if there are particular places where it tends to hover or turn around. This particular dragonfly was flying low and not too far from the shore of a small pond.

Focusing is the biggest problem. Some photographers like to pre-focus on an area and wait for the dragonfly to fly into that area. Others will rely on the auto-focus capabilities of their cameras. I have had almost no success with those techniques. What I usually do is put my camera’s focus into manual mode and literally change focus on the fly as I attempt to track the dragonfly in the air.

I like to use my Tamron 180 mm macro lens, because it gives me a decent amount of reach and frees me from worrying about zooming in and out. I have found that simultaneously zooming and focusing manually while tracking the dragonfly is like patting your head and rubbing your stomach at the same time—it is theoretically possible but tough to accomplish in real life.

If you click on the image and view it in a larger size, you will see that I was fortunate to get my focus just about right for the middle of the dragonfly’s body. The shutter speed of 1/1000 of a second was fast enough to freeze most of the movement of the wings.

Needless to say, I took a lot of shots and my success rate was very low. Perhaps this is not your idea of a “fun” challenge. In that case, I would encourage you to find some area of your life and challenge yourself to do something that is difficult. Even if you are not successful, I think even the effort will help you to grow, especially in self-knowledge and self-awareness.

Odonata is an order of insects that includes dragonflies and damselflies. In general, dragonflies tend to be larger and perch with their wings held out to the sides, while damselflies are smaller, have more slender bodies, and most  hold their wings over the body at rest. I try to pay attention to members of both damselflies and dragonflies, but often spend more time with the latter group, because they are easier to find and photograph.

In the interest of equality, I decided to devote today’s post to some of the female Fragile Forktail damselflies (Ischnura posita) that I have observed this past week. The three images show female Fragile Forktails in three of their main activities—perching, eating, and ovipositing (laying eggs). I have no recent shots of the mating that precedes the ovipositing, so I will leave that to your imagination for now.

As you probably noted, the coloration of these lady damselflies varies. The damselfly in the first image with the distinctive markings is an immature female. As the females age, they acquire a bluish coating that is sometimes referred to as pruinescence, which you can especially see in the second image. The third image shows a damselfly arching her long abdomen as she deposits eggs in the debris floating on the surface of a small pond.

Sometimes I can identify a dragonfly by the way that it perches. Some dragonflies like to perch high on the tip of vegetation and some perch low to the ground or even on the ground itself. Some will hang vertically or perch horizontally or at an angle somewhere in between.

On the rare occasions in the past when I have seen a Common Green Darner (Anax junius) perch (usually I see them in the air), it has usually been in vegetation relatively low to the ground. I was therefore surprised to see one spreadeagled on the side of a tree on Monday at Patuxent Research Refuge in Laurel, Maryland. Of course, the bright green color and the bull’s-eye pattern on the face made it easy to identify this dragonfly, despite her unconventional perching pattern.

I have learned from experience that the wildlife subjects that I love to photograph often do not look or act the way in the ways described in books. They are may also be found in different habitats or at different times than the range maps indicate. That is what makes this type of photography so challenging and so rewarding and it means I have to be constantly alert and vigilant when out in the field.

What is your first thought when you see these three turtles together? Are they just friends or more than friends? The turtles seem to be pretty comfortable sharing a confined space and there is plenty of space in our minds for varied interpretations on the nature of their relationship. According to the old saying, “two’s a couple and three’s a crowd”—is that always true?

Whatever the case, the turtles at Occoquan Bay National Wildlife Refuge have been definitely been enjoying our recent sunny days. My turtle identification skills are not very good, but I think these all may be Eastern Painted Turtles (Chrysemys picta picta), though there is a chance that they might be Red-eared Sliders (Trachemys scripta elegans).

I love images like this one that allow viewers to use their creativity to interpret what they see and to generate in their minds their own mini-narrative of what is going on. Ménage à trois or just friends—you make the call.

Yesterday was a wonderful day for searching for dragonflies at Occoquan Regional Park and among my finds was this beautiful female Painted Skimmer (Libellula semifasciata). This is the first one of the season for this species, which is relatively common compared to most of the early spring species. The patterns on the wing make this species stand out and definitely help in identifying.

I love the way that the different colors on this dragonfly work so well together and give this dragonfly a refined and rather sophisticated look. It is an additional bonus that those colors are mirrored by the background colors in this image.

When it comes to choosing a nesting site, Ospreys (Pandion haliaetus) at Occoquan Bay National Wildlife Refuge seem to be opportunistic. Some lucky couples are able to snag pre-existing nesting sites that require only minor improvements, while others are forced to build entirely new nests.

This past Thursday I photographed a nest that is annually built on top of one of the duck hunting blinds in the waters off of the wildlife refuge. Earlier in the season, the ospreys would fly away as I walked by on a trail, but now that the trees are leafing out, the ospreys have a bit more privacy.

The nest in the second image is a new nest, built in the last couple of weeks and probably still under construction. It is adjacent to the location where the nest in the third shot used to be. For reasons that are not clear to me, that nesting platform has disappeared and only a part of the post remains. I believe that the new nest may have been built by  the couple that occupied that nesting platform earlier in the season.

When presented with a downward-facing flower, this Eastern Tiger Swallowtail butterfly (Papilio glaucus) was forced to choose an unusual angle of attack. Seeming defying gravity, this acrobatic butterfly hung upside down as it probed upwards earlier this week at Prince William Forest Park in Triangle, Virginia.

If this were an Olympic competition, I would give him a 10 for both his technical skills and overall artistic impression.

I sometimes complain about the names given to species and how little they correspond to what I actually see in the field. That certainly was not the case yesterday when I spotted a Twin-spotted Spiketail dragonfly (Cordulegaster maculata) along a creek in Northern Virginia. If you look closely at the image, ideally by double-clicking it, you will see the double row of spots on the dragonfly’s abdomen (the “tail”) and the long pointed ovipositor extending well beyond the end of the abdomen, the “spiketail.”

As I post photos of dragonflies, I realize that it is hard for readers to get a feel of the relative size of these beautiful creatures. The Uhler’s Sundragons that I have featured recently are about 1.7 inches in length (44 mm). A Twin-spotted Spiketail, by contrast, is much larger, about 2.8 inches in length (69 mm).

Both of these species are uncommon to rare in our area, primarily because of their specific habitat requirements—they require clean forest streams, which are not common in the Washington D.C. metropolitan area and they have an early and short flight season of only a few weeks.

You know you are pretty close to a dragonfly when you can see individual grains of pollen on its head and body. I photographed this Uhler’s Sundragon dragonfly (Helocordulia uhleri) on 12 April alongside a creek in Northern Virginia. Ideally it would be best to stabilize macro shots taken at this close a range by placing the camera on a tripod, but in a field situation with a live subject, that is rarely possible.

If you click on the individual images, you will see some wonderful details, like the ommatidia, the individual optical units that make up the amazing compound eyes of these dragonflies.

As we move deeper into spring, more and more butterflies are starting to appear, like this beautiful Zebra Swallowtail (Protographium marcellus) that I spotted yesterday at Accotink Bay Wildlife Refuge. Zebra Swallowtails are most often associated with pawpaw trees, which is helpful to know, though I must confess I don’t know how to identify a pawpaw tree. What I do know is that these butterflies are constantly on the move and fly in such an erratic way that I have trouble getting a decent photograph of one.

Yesterday I managed to get a shot of a Zebra Swallowtail when it paused momentarily at a small tree, perhaps a possible pawpaw. What I like about the shot is that it shows well the colors of the butterfly as well as its long “tails.” I could not decide how much to crop the image, which was taken from a pretty good distance away, so I am including tow versions of the image. Personally I am drawn most to the second one, but recognize that many folks may prefer the first versions, which draws you more quickly to the butterfly’s beautiful details.

Do you associate certain colors with certain seasons? For me, yellow is definitely a springtime color. After months of winter weather dominated by shades of gray and a palette of faded colors, spring explodes with bright colors, with yellow daffodils popping up all over the place. Usually I have to wait a bit longer for yellow to pop up in the birds and insects that I enjoy photographing.

As I was exploring with my camera this week, I ran across bright yellow subjects in two very different locations. One, a Pine Warbler (Setophaga pinus) was quite appropriately perched high in a pine tree. The second was an Eastern Tiger Swallowtail butterfly (Papilio glaucus) that appeared to be probing the sand on the bank of a forest creek. I suspect that the butterfly needed the minerals and salts, although I confess to initially thinking that butterflies needed only nectar from flowers for sustenance (and there were definitely no flower in the area of that creek).

On Wednesday I finally photographed my first dragonflies of the season, some Uhler’s Sundragons (Helocordulia uhleri) that I spotted while exploring a creek in Northern Virginia. This was my first time seeing this species and I was particularly excited, because it is considered to be rare in my area. According to the Dragonflies of Northern Virginia website, this species is a “scarce and seldom seen member of the emerald family” and is a “habitat specialist with a brief and early flight period.”

Initially I took some medium distance shots with my 180mm macro lens and them moved in closer to get the first shot. In order for me to get such a close-up shot, the dragonfly has to be cooperative and this female Uhler’s Sundragon was quite accommodating.

As you probably notice in the first photo, only a limited amount of details are in focus when shooting a subject this close.  One of the biggest challenges is to ensure that the most important features are the sharpest. Following the usual rule for photographing live subjects, I attempted to focus on the eyes.

For me, dragonfly season is now open and I anticipate that I will be featuring different species of these beautiful aerial acrobats quite regularly in the upcoming months.

Can you actually see a sound? Yesterday while I was exploring Prince William Forest Park, I heard a whole lot of croaking. Eventually I spotted one really loud male toad with an inflated vocal sac, which was pretty cool. What were even cooler were the concentric ripples in the water generated by the toad’s croaking.

The second image shows the toad resting in between performances, whose main purpose is to attract mates. His song did not appear to have had any immediate benefits, although I was certainly impressed.

UPDATE: I initially identified this as a frog, but fellow blogger and wildlife enthusiast Walter Sanford pointed out to me that this is probably an American Toad (Anaxyrus americanus).

I’m still looking for my first dragonfly of the season, but was thrilled yesterday afternoon when I spotted my first damselfly, a Fragile Forktail (Ischnura posita), at Jackson Miles Abbott Wetland Refuge. In anticipation of seeing one of these small insects, I mounted my Tamron 180mm macro lens on my camera, a lens that has gone largely unused during the long winter months in favor of my telephoto zoom lens.

Yesterday was a nice reminded of how much I enjoy using a macro lens. (To give you a sense of scale, a Fragile Forktail damselfly is about 0.8-1.1 inches in length (21-29mm).)

Ospreys (Pandion haliaetus) in my area have been building nests in all kinds of places, including on some channel markers in the Potomac River off of Occoquan Bay National Wildlife Refuge. I personally don’t really think that there is enough space there for a nest, but the ospreys seem to think otherwise.

I am amused by the “No wake” sign that they have chosen. During busy periods, I would think that “No sleep” would be more appropriate.

Have a wonderful weekend. 🙂

There is no doubt that I love photographing majestic raptors, like the bald eagles that I regularly feature. Yet there is something equally special about capturing images of tiny songbirds, like this perky little Blue-gray Gnatcatcher (Polioptila caerulea) that I spotted earlier this week at Occoquan Bay National Wildlife Refuge.

How small are these birds? According to the Cornell Lab of Ornithology, Blue-gray Gnatcatchers are 3.9-4.3 inches in length (10-11 cm) and weigh 0.2-0.3 ounces (5-9 grams), just slightly larger than a hummingbird. The same source notes that, despite the bird’s name, gnats do not form a significant part of a Blue-gray Gnatcatcher’s diet.

Who comes up with these names?

A Bald Eagle (Haliaeetus leucocephalus) paused for a moment to check on its catch as it flew away on Monday at Occoquan Bay National Wildlife Refuge. Occasionally I will see an eagle flying with a fish in its talons, but it is quite rare for me to see an eagle actually catch the fish.

In this case, I was fortunate enough to spot an eagle circling low over the water and I captured a few images just after the eagle snagged the fish. In the second shot, which chronologically speaking was the first shot, you can just make out the fish. In the third shot, the eagle appears to be adjusting itself to the additional weight and is starting to increase its speed and altitude.

These are the kind of action shots that I love to capture. I never know when such situations will arise, so I always try to remain ready to react.

On Monday it was cool and windy and I didn’t expect to see many birds at Occoquan Bay National Wildlife Refuge. I was pleasantly surprised to spot several Bald Eagles (Haliaeetus leucocephalus) flying about. The wind seemed to slow them down a little and gave me a slightly better chance of capturing images of them in flight.

My favorite subject was this juvenile eagle. Sometimes juveniles can look somewhat bedraggled with their multi-colored feathers, but I thought that this one looked quite handsome, especially when the light hit it from a good angle and illuminated its body. One unexpected benefit was that it was easier to get a proper exposure with the juvenile because it does not have the extreme contrasts of the dark body and white head of the adults. In many of my shots of adult eagles, the body ends up underexposed and/or the head ends up overexposed.

Yesterday at Occoquan Bay National Wildlife Refuge I spotted my first warbler of the spring, a Palm Warbler (Setophaga palmarum). For several weeks, I have been diligently searching the ground and the trees for warblers, whose appearance marks the beginning of spring for some birders. It was not surprising that the first one I saw was a Palm Warbler, because they are traditionally one of the earliest species to arrive, but I was a little surprised to find several of them at water’s edge, poking about in the rocks and the debris. In the past, I have most often spotted them on the grassy trails.

I was not able to get close to these little warblers, so my normal temptation was to crop my images, as I did in the first one, in order to highlight the bird. As I was working on the second image, I decided I liked the idea of including more of the environment, even though it is a bit cluttered. What do you think?

Some birds are so round in appearance that they look more like cartoons than real birds. That was certainly the case with this tiny Ruby-crowned Kinglet (Regulus calendula) that I spotted last week at Occoquan Bay National Wildlife Refuge.

Yesterday I spotted this pair of Eastern Bluebirds (Sialia sialis) perched on a nesting box at Occoquan Bay National Wildlife Refuge. The female appeared to have nesting materials in her bill and seemed ready to build a nest. The only problem is that this nesting box, I believe, is currently being used by some Tree Swallows.

I don’t know for sure if this is the place where the bluebirds plan to make their nest and I never did see either of the bluebirds enter the nesting box. However, a short time later I spotted the male bluebird with nesting material in his bill, so it is quite likely that they are determined to construct a nest somewhere nearby.

Normally when I see a Northern Mockingbird (Mimus polyglottos), it is perched in a tree. This past Wednesday at Occoquan Bay National WIidlife Refuge, I spotted one foraging in a field. The mockingbird was perched on the stalks of the vegetation and periodically would bend down and grab a few seeds.

I love the way that the cooler tones of the bird contrast with the warmer shades of the vegetation and the background. That contrast makes this fairly common bird really stand out and shine.

During one of my recent early morning forays to Occoquan Bay National Wildlife Refuge, I was thrilled to spot several beavers. I had seen plenty of gnawed off trees in the area around this pond, so I knew that there had to be some beavers nearby. You generally have to be really lucky to see one, because they are mostly nocturnal creatures.

There were three beavers when I initially spotted them swimming towards me. Two of them seemed to sense my presence as they got a little closer and dove underwater. One kept approaching and I was able to capture the first image, a head shot  of a handsome North American Beaver (Castor canadensis). The second image shows the beaver as it was swimming and gives you a better sense of the environment in which it was found.

I love the sweet sounds of a Carolina Wren (Thryothorus ludovicianus), like this little beauty that I spotted on Wednesday at Occoquan Bay National Wildlife Refuge.  Most of the times when I see a Carolina Wren, it is hopping about in the underbrush, but sometimes when they are going to sing, they choose a higher, more visible perch.

This past Monday I spotted this juvenile Cooper’s Hawk (Accipiter cooperii) high in a tree at Occoquan Bay National Wildlife Refuge. Initially there were a lot of branches between us, but I was able to move slowly and stealthily closer to the little hawk and get a relatively clear shot of it.

This past week at Occoquan Bay National Wildlife Refuge I observed two large birds consuming large fish using very different techniques. The first, a Great Blue Heron (Ardea herodias), carefully positioned the fish and then swallowed it in a single big gulp.

An Osprey (Pandion haliaetus), pictured below, used a much slower and methodical approach, tearing small chunks off of the fish. It takes a lot of bites to finish off a fish in this way. In between bites, the osprey would often look around to make sure no other bird was approaching and attempting to steal its catch.

When it needed to tug extra hard on the fish, the osprey would sometimes extend its wings in what I assume was an effort to stay balanced and keep from falling out of the tree. I believe that is what was going on at the moment when I captured this image.

This Bald Eagle (Haliaeetus leucocephalus) dropped more quickly than I anticipated when it took off last Friday at Occoquan Bay National Wildlife Refuge, but somehow I managed to keep most of it within the frame.

Whenever I see an eagle perched in a tree, my mind starts to go into overdrive and my fingers get twitchy. Should I take an immediate shot or should I try to get closer? If I manage to get closer, should I zoom in all the way to capture the perched eagle or leave room in the frame if the eagle decided to take off? I try to anticipate what is going to happen, knowing that I will most likely will have to react to a scenario that I hadn’t predicted.

This eagle, for example, did something unusual—it initially flew towards me. In my experience, eagles almost always fly away from me when they take off. A bird flying right at you is a real challenge to photograph. My focus on the eagle’s eye was off a little bit, but I was very happy to capture an image in which I am looking straight at the eagle’s face from in between the wings.

Growing up, I was a member of the Boy Scouts and the Scout motto of “Be Prepared” serves me well when I am trying to photograph wild creatures like this bald eagle.

When I accidentally flushed this enormous Pileated Woodpecker (Dryocopus pileatus) last week at Occoquan Bay National Wildlife Refuge, it flew to another tree and tried to hide from me.

Note to woodpecker—you need to find a much bigger tree if you want to avoid being seen.

I captured this image this past Tuesday morning at Occoquan Bay National Wildlife Refuge as an Osprey (Pandion haliaetus) was starting to take off from its perch high in a tree with a partially eaten fish firmly in its grasp. I had watched the osprey consume the top portion of the fish and hope that it was carrying the remainder to its mate.

I am somewhat romantic, so I want to believe that this is a story about love and sharing and caring—and maybe it is. It is also possible that the osprey is selfish and fearful and is seeking a more secluded, secure perch when it can enjoy the rest of its catch without having to worry about it being stolen by eagles or potential predators like me.

Whatever the reality of the actual situation, I love the way that this image shows off the osprey’s impressive wingspan and how the v-shape of the wings is repeated in some of the branches and in the tail of the fish.

Why did the Snapping Turtle (Chelydra serpentina) cross the road? It sounds like the opening line of a joke, but I asked myself that question yesterday when I spotted a snapping turtle lumbering its way across one of the trails at Occoquan Bay National Wildlife Refuge. The turtle’s back was covered with mud, suggesting it had only recently emerged from its winter sleep. In the past I have sometimes seen snapping turtles out of the water when they were getting ready to lay eggs, though it seems a little early for that to be taking place.

I have always thought that snapping turtle look like dinosaurs. What do you think?
