It’s always fun to encounter cute little rabbits like this one that I spotted recently as I was walking along one of the trails at Occoquan Bay National Wildlife Refuge.

I do not see a lot of mammals during my walks, with the notable exception of squirrels, so I am always happy to see a rabbit or a deer or a beaver. As most of you know, I tend to see a lot more insects and birds and that is one of the reasons why they appear so often in my postings.

On the sides of some of the trails at the refuge there are heavy thickets and my observations suggest that they are the preferred habitat for the rabbits, which are almost certainly Eastern Cottontail rabbits (Sylvilagus floridanus).  The rabbits at the wildlife refuge generally seem to be very cautious, which is probably a good survival tactic, considering the number of hawks and eagles in the area.

This particular rabbit froze in place for a moment when it first detected me, allowing me to get this shot. After a brief pause, it scampered away into the safety of the heavy vegetation.

I love the effects of the light in this image of a Great Egret (Ardea alba) that I captured on Tuesday at Occoquan Bay National Wildlife Refuge. (For the sake of clarity, I should note that I captured the image and not the egret.) When I first spotted the egret, its wings were down and it was more or less just a silhouette. As I was focusing on it, though, the egret hopped into the air and flapped its wings and I snapped the shot. I was looking almost directly into the sun and I was fascinated by the way the light illuminated the outstretched wings and was happy that I was able to capture, at least in part, that effect.

Wandering Gliders (Pantala flavescens) are the most widespread dragonfly species in the world and are found on all continents except Antarctica. I was thrilled on Tuesday when one stopped wandering for a moment at Occoquan Bay National Wildlife Refuge and I was able to capture this image. According to Wikipedia, individual Wandering Gliders can fly more than 3730 miles (6000 km)—one of the farthest known migrations of all insect species.

Most of my dragonflies have disappeared for the season. I will still occasionally spot a few survivors of the summer species, but their numbers are dwindling in the cooler autumn weather. One notable exception is the aptly named Autumn Meadowhawk dragonfly (Sympetrum vicinum). On Tuesday I spotted a good number of Autumn Meadowhawks while exploring Occoquan Bay National Wildlife Refuge and captured these images with my long telephoto zoom lens—it is a bit of a challenge to focus on such a small subject with a lens zoomed out to 600mm.

In the area in which I live, Autumn Meadowhawks remain with us throughout October and November. I have personally spotted some in December and have heard of other sightings in early January.

Two Black Vultures (Coragyps atratus) appeared to be intently staring at me as I drew closer to them on Tuesday at Occoquan Bay National Wildlife Refuge. Were they sizing me up, hoping I might drop dead on the spot? As Halloween approaches, it is easy to feel a little creeped out in situations like this. Although I believe that they were simply curious about my presence, I did make sure that I moved around enough to ensure that the vultures knew that I was still alive.

Any day that I spot a Bald Eagle (Haliaeetus leucocephalus) is a good day. Yesterday qualified as a great day when I was able to capture an image of a Bald Eagle taking off from the slender branches of a tree at Occoquan Bay National Wildlife Refuge.

I was a bit shocked when I initially spotted the eagle perched in a cluster of leaves overhanging one of the trails at the wildlife refuge—presumably there was a branch in there somewhere, but it did not seem substantial enough to hold the weight of an eagle.

I zoomed in all the way with my 150-600mm lens and was able to get a pretty detailed shot of the eagle, as you can see in the final shot. The eagle turned its head in various directions and I knew that I did not have much time before it decided to take off. When the eagle turned its body toward the water and began to crouch, I tried to ready myself and anticipate the direction of its initial movement. In most of the shots in the burst that I took, the eagle’s wings blocked its face or extended well beyond the edges of the frame, but I was pretty happy with the one that I posted as the initial photo in this posting.

Why did the eagle choose such a precarious perch? I have no idea why, but I am happy that it gave me the chance to get these shots.

We are in a period of transition. All around I see the signs of autumn, but summer has not completely loosed its grasp. Last week I spotted this female Eastern Pondhawk dragonfly (Erythemis simplicicollis) at Occoquan Bay National Wildlife Refuge. Eastern Pondhawks are among our most common dragonflies—they are still with us, but their numbers are clearly dwindling.

In this image I really like the juxtaposition of the dragonfly’s bright summer coloration with the more muted autumn colors of the fallen leaves, a visual representation of this time of transition.

I spotted a Great Blue Heron (Ardea herodias) perched in a tree last Friday at Occoquan Bay National Wildlife Refuge, calmly surveying the area, as shown in the second shot. As I drew closer, I could sense the heron beginning to gather itself.  I managed to capture the first image as the Great Blue Heron leaped into the air, preparing to take flight.

This Bald Eagle (Haliaeetus leucocephalus) was so well hidden in a tree on Friday at Occoquan Bay National Wildlife Refuge that I almost missed it. Fortunately I caught a glimpse of the sun reflecting off of its bright white head and was able to move close enough to capture this image.

As you may have noticed in recent postings, I have marked the changing of the seasons by changing my “walk around” lens from a Tamron 180mm macro lens to a Tamron 150-600mm telephoto zoom lens. This means that it is easier for me to get photos of birds like this eagle, but tougher, though not impossible, to capture images of the remaining butterflies and dragonflies.

It won’t be long until all of the Great Egrets (Ardea alba) leave my area and head for warmer locations. That makes each encounter now with a Great Egret even more special. Yesterday while I was exploring Occoquan Bay National Wildlife Refuge, I spotted this egret perched high in a tree. Initially my view was blocked by a lot of branches, but eventually I was able to maneuver into a position from which I could get an unobstructed shot.

I really like the way that the branches act as a natural frame for the egret. Additionally I like the whimsical element of the feather sticking up on the bird’s head—it reminds me of the cowlick that I had as a young boy, back when I had hair. Sometimes my Mom would lick her fingers and unsuccessfully attempt get my hair under control.

When I spotted this raptor flying over a distant field earlier this week at Occoquan Bay Wildlife Refuge, I suspected that it was a Northern Harrier (Circus hudsonius). Although I do not see this species very often, Northern Harriers fly in a very distinctive way—they glide low over grasslands and marshlands, in part because they rely on their sense of hearing  when hunting.

I was a little disappointed that this harrier, which several folks in a Facebook birding group identified as a female, made only a single pass over the field and never flew very close. However, I am pretty happy that I was able to capture this image that gives you a good sense of the flight profile of the harrier and the environment in which she was flying.

Yellow-rumped Warblers (Setophaga coronata) have returned in force to Occoquan Bay National Wildlife Refuge. There are still lots of leaves on the trees, though, so it is a real challenge to get unobstructed shots of them. I catch sight of them moving in and out of the foliage, but only rarely do they pop out into the open. So I patiently watch and wait.

Here are pretty clear views of Yellow-rumped Warblers that I eventually managed to capture on Wednesday. Most warblers are in our area only briefly as they make their way north in the spring and south in the autumn. Yellow-rumped Warblers, however, remain with us for much of the winter, so I may have more chances to see them better as the trees gradually give up their leaves.

When I spotted a small patch of milkweed while exploring Occoquan Bay National Wildlife Refuge earlier this month, I stopped and waited. I knew that numerous butterflies are attracted to this plant. Before long, several butterflies in fact appeared.

Here are photos of two of them, both swallowtail butterflies. The first one, a Spicebush Swallowtail (Papilio troilus), appears to be in perfect condition. Its wings and “tails” are intact and its colors are vibrant. By contrast the second butterfly, a Zebra Swallowtail (Protographium marcellus), is clearly a veteran. There are chunks missing from its wings and its long beautiful swallowtails are gone.

Do you find one of the butterflies to be more inherently beautiful than the other? Here in the United States, we tend to worship beauty and a standard of supposed perfection. We are daily bombarded with advertising messages that tell us we can look young again, that we can cover up our imperfections. The current focus on selfies and dating apps that allow you to judge others with a swipe encourages a kind of narcissism and attention to superficial appearances that I personally find to be unhealthy.

I remember watching a video several years ago about photographing nature. The photographer encouraged viewers to photograph only perfect specimens of flowers and insects, following the lead of those who say that in order to create beautiful photographs, you need beautiful subjects.

The photos here are my response to that kind of thinking. There is an incredible beauty to be discovered in the ordinary, everyday subjects that surround us, full of imperfections and blemishes. Take a moment today to slow down and truly experience that beauty.

The most common view that I have had of White-tailed Deer (Odocoileus virginianus) the last few months has been of their bobbing tails as they ran away from me. Last week, however, I managed to capture some shots of a young buck as it ran laterally across a trail at Occoquan Bay National Wildlife Refuge.

When I first spotted the deer, its head was just sticking out of the vegetation at the edge of the trail. As you can see in the first image, the deer looked straight at me and seemed to hesitate a moment before deciding what to do. Without much warning, the deer sprung into action and I was able to capture these shots as the young deer bounded across the trail. Note how the deer had only a single hoof in contact with the ground in many of the photos.

I have not yet spotted any Monarch butterflies this season, but last week at Occoquan Bay National Wildlife Refuge I did see a number of the similarly-colored Viceroy butterflies (Limenitis archippus). Viceroy butterflies are smaller than Monarchs, but the main visual difference between the two is the black line across the hind wings that is present with Viceroys, but not with Monarchs.

I chased after one Viceroy last week for quite some time and eventually managed to get these shots.

Now that the foliage on the trees  is full, it is hard for me to monitor the status of the baby eagles in several Bald Eagle (Haliaeetus leucocephalus) nests at Occoquan Bay National Wildlife Refuge. On Wednesday, however, I detected some motion as I was peering at one of the nests and realized that it was the flapping of an eaglet’s wings. I managed to find a visual tunnel through which my view was mostly unobstructed and was able to capture this view of two eaglets. I was shocked to see how big they have grown and suspect that they soon will be flying.

The nest is probably too small to hold the adults along with the youngsters—what I would call “full nest” syndrome, i.e. the opposite of the more commonly known “empty-nest” syndrome. The second image shows one of the presumed parents perching on a higher branch of the tree in which the nest is located.

This time of the year is always exciting for me as my favorite dragonfly species begin to emerge—it is like renewing a relationship with old friends after an extended absence. On Monday at Occoquan Bay National Wildlife Refuge I was thrilled to spot my first Calico Pennant (Celithemis elisa) dragonflies of the season.

As dragonflies go, Calico Pennants are small, a little over an inch (25 mm) in length and very colorful. In addition to their bright red (male) and yellow (female) bodies, they have beautifully patterned wings. Like other pennant dragonflies, Calico Pennants like to perch at the very tip of flimsy grasses and other vegetation. That makes them fairly easy to spot, but tough to photograph as they flap in the slightest breeze like a pennant.

I spotted a number of male Calico Pennants during my visit, but only a single female, the one that is mating with a male in the final photo. For those of you with curiosity or prurient interest, the couple are hooked up in what is often referred to as the “wheel position.” Anatomically speaking, it is a bit confusing, but you have to admire the couple’s acrobatic flexibility. The first two photos show perched males, with the initial photo a back-lit image that shows wing details and the second one a more traditional pose that highlights the body coloration.

Yesterday I was thrilled to get a glimpse of this impressive-looking Wild Turkey (Meleagris gallopavo) at Occoquan Bay National Wildlife Refuge. I have seen Wild Turkeys at this refuge on numerous occasions, but this is one of the first images that I have been able to capture this spring.

I am always amazed when I come upon a male turkey displaying his feathers. I grew up in the suburbs of Boston and the only turkeys that I ever saw were those in the freezer at the supermarket, which did not look anything like this bird, and the cutout figures that we would pin to the wall to celebrate Thanksgiving. Somehow I always thought those cutouts were cartoonish caricatures—little did I know that wild turkeys actually look like those colorful figures.

Do you like to hang out in the swamp? Swamps may not be the most hospitable place for humans, but they provide a wonderful environment for all kinds of photogenic creatures. For example, the bright yellow Prothontary Warbler that I featured yesterday likes to hang out in a wooded swamp, unlike most warblers that prefer trees in a drier environment.

As I was photographing that bird two weeks ago at Occoquan Bay National Wildlife Refuge, I noticed some very large dragonflies flying around in the same area.  I recognized them as Swamp Darner dragonflies (Epiaeschna heros) and I was thrilled when one of the females decided to deposit some eggs in a fallen log not far from where I was standing observing the warbler. I had to bend down a bit, but essentially my feet stayed in the same spot.

It is definitely cool to be able to photograph two such colorful species from the same spot. The experience is a good reminder not to get so focused on your primary subject that you lose sight of what is happening around you. You never know when an equally good or even better subject may be at your feet, above your head, or to your right or left.

A couple of weeks ago I spotted a colorful Prothonotary Warbler (Protonotaria citrea) building a nest in a nesting box at Occoquan Bay National Wildlife Refuge. The warbler made multiple trips to the nest carrying a variety of materials in its bill. Each time that it got ready to leave the box, the warbler would stick its head out and look around. Although I tried repeatedly to capture the bird in flight as it left the box, the last image was the only one that was partially successful.

I am finally catching up on a backlog of photos—normally I post my photos within a few days of shooting them.

The sky was mostly covered in clouds yesterday morning at Occoquan Bay National Wildlife Refuge when an Osprey (Pandion haliaetus) decided to fly right at me after it had caught a fish.

I love the look of a head-on shot of a flying bird, but capturing such a shot is not easy. First, the bird has to cooperate and most of the time, it seems, birds like to fly away from me and not toward me. Secondly, I have to be able to capture and maintain focus on the bird as it is approaching, which can be a challenge with a heavy telephoto zoom lens. Finally, I have to calibrate my shooting speed so that I don’t fill up the buffer of my camera before the bird gets close.

Things worked out pretty well for this shot. If you click on the image and zoom in on it, you will see that I managed to keep those yellow eyes in reasonably sharp focus and even the beak is in focus. You don’t get a very good view of the fish—you will have to wait until I capture of profile shot of an osprey with its catch.

Many of you are aware that I have been keeping track of a Bald Eagle (Haliaeetus leucocephalus) nest at Occoquan Bay National Wildlife Refuge. When the eagle couple occupied the nest earlier this spring, the authorities set up barriers to keep the eagles from being disturbed, because the tree with the nest is close to the intersection of several trails.

I have checked the nest several times in the past month and there has always been an eagle sitting in the middle of the nest. As I looked through my telephoto zoom lens this past Friday from one of the barriers, I could see that an adult eagle was sitting at one side of the nest, leading me to believe there might be babies. I waited and eventually was rewarded with a view of one eaglet.

Last year there were two eaglets born at this nest. Perhaps there is a second eaglet this year too, but at a minimum I am thrilled to know that there is at least one new eaglet birth to celebrate.

Last Friday I spotted this Common Loon (Gavia immer) in the waters off of Occoquan Bay National Willdife Refuge.  I don’t think that I have ever actually seen a loon before, but this bird pretty much matches the image of a Common Loon in breeding plumage in my bird identification guide. The range maps indicate that Northern Virginia, where I live, is in a migratory area for this species. I am guessing that this loon stopped for a while on his journey northward.

Most of the warblers that I am fortunate enough to see are partially hidden by branches. Although hope is usually not an effective technique for taking photos, essentially that is what I do when I spot a hidden warbler—I start shooting and hope that the little bird will reveal itself enough for me to capture a clear shot of at least its head.

That was the case on Friday when I shot numerous photos in an attempt to capture an image of this Prothonotary Warbler (Protonotaria citrea) at Occoquan Bay Naational Wildlife Refuge. Unlike many warblers that are found bushes and in trees in more open area, Prothonotary Warblers are creatures of the swamp. I initially spotted one of these beautiful birds in a marshy area and was thrilled when one of them eventually made its way into some vegetation overlooking the water.

According to the Cornell Lab of Ornithology, the Prothonotary Warbler got its name from the bright yellow robes worn by papal clerks, known as prothonotaries, in the Roman Catholic church. This background information is fascinating, though I must confess that it is hard to find an opportunity to inject the word “prothonotary” into an everyday conversation unless I am talking about this bright yellow bird.

Yesterday at Occoquan Bay National Wildlife Refuge I was excited to spot a colorful little bird that was new to me. A search through my bird identification guide and some help from my Faceboook friends helped me to determine that it is a Prairie Warbler (Setophaga discolor).

I am hoping to be able to spot some more warblers this spring while their plumage is particularly colorful. I observed a few warblers last fall and noted that their coloration was a lot more subdued than it is now.

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.

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.

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.
