Last Friday I almost literally stumbled upon a young White-tailed Deer (Odocoileus virginianus) during a visit to Occoquan Bay National Wildlife Refuge. As I turned a corner, I suddenly spotted this little deer slowly coming towards me. I immediately stopped, but the deer initially kept on walking. I noticed that the deer had nubs on its head instead of antlers. Was this a buck who was too young to grow antlers or was this a somewhat older deer who was regrowing his antlers?

I grew up in the suburbs of Boston and confess that I know very little about deer. I do know that male deer shed their antlers during the fall and winter and then regrow them in the spring each year. According to the Fish and Wildlife Service, antlers are the fastest bone growth in the world and the antlers of an adult White-tailed Deer can grow 1/4 inch (6 mm) a day and those of an elk can grow an inch (25 mm) a day.

This deer seemed more curious about me rather than afraid of me and eventually moved only a few feet off of the trail to let me pass. I was happy to see this beautiful young animal in its natural habitat. In many parts of the suburban area surrounding Washington D.C. there is an overpopulation of deer and a variety of measures are used to try to control the population. At this wildlife refuge, for example, several deer hunts are conducted each year.

I personally am not a hunter, but I do recognize the dangers that deer overpopulation poses to the habitat, to the human population, and to the deer themselves. When I am out with my camera, though, I am not thinking about these things, but instead am focused on sharing the beauties of nature and peacefully coexisting with my fellow creatures, like this young deer.

This past Friday I was delighted to spot some mature male Calico Pennant dragonflies (Celithemis elisa) at Occoquan Bay National Wildlife Refuge. Earlier this season I had seem some immature male Calico Pennants who still had yellow bodies. As they mature, male Calico Pennants turn red in a pattern that looks like a column of little hearts, as you can see in the second photo below.

Like other “pennant” dragonfly species, Calico Pennants like to perch precariously on the very tips of vegetation. Even the slightest breeze will cause them to flutter, like pennants in the wind.

You can’t help but notice the beautiful patterning in the wings that makes this species stand out from almost all other dragonfly species. Wow!

I took the first two photos when the dragonflies were perched nearby in the vegetation. Periodically the dragonflies would fly out over the water of a small pond at the wildlife refuge and would perch at the water’s edge. The shoreline was really mucky, so I could not get close to these dragonflies. I was happy, though, to be able to capture the final photo below, an “artsy” minimalist view of a Calico Pennant perched at an almost right angle on a slim blade of vegetation.

I was delighted yesterday during a visit to Occoquan Bay National Wildlife Refuge to spot this beautiful female Needham’s Skimmer dragonfly (Libellula needhami), my first of the year. Later in the year, Needham’s Skimmers will become the most frequent dragonfly that I will encounter at this location but the dragonfly in the photo below was the only one that I saw yesterday.

Needham’s Skimmers are quite distinctive in appearance. Mature males are reddish-orange in color and stand out from the males of other species. Females and immature males have a body coloration that is shared with some other species, but the golden yellow veins at the leading edges of their wings distinguishes them from the others.

Blue Corporals (Ladona deplanata) are an early-season dragonfly—they appear in April and are usually gone by the beginning of June. I was therefore happy to spot some Blue Corporals in mid-May during a visit to Occoquan Bay National Wildlife Refuge. Blue Corporals perches frequently on low flat surfaces, often on the ground, so they are sometimes hard to see when the ground is cluttered, as it often is at this time of the year.

The dragonfly’s “corporal” stripes on his thorax are really visible in the first photos, so I could immediately identify his species. A short time later I was surprised when I saw a Blue Corporal land on a rusty bit of metal sticking out of the water at the edge of a small pond—I haven’t seen Blue Corporals flying over the water very often. I think this might have been a fence post or some kind of marker, because it appeared to be attached to some concrete.

I was absolutely delighted to be able to captures the texture of the rusty metal and the orange-blue complementary colors make this image particularly eye-catching.

When I first spotted two Ospreys (Pandion haliaetus) sitting in a large eagle nest last week at Occoquan Bay National Wildlife Refuge, I assumed that one of them was sitting on eggs. I was therefore a bit surprised when one of the ospreys mounted the other in what I assume was an act of mating. That suggests that there are not yet any eggs in the nest.

After a brief period of activity, the one that is probably the male flew away from the nest and I managed to capture a couple of photos of his departure. Both of the ospreys are in the frame in the second and third photos below and I really like the way that I captured the wing span of the departing osprey and his spread tail feathers. I encourage you to click on these two images to get a closer look at the ospreys, particularly the male.

I usually try to get close-up shots of dragonflies, but sometimes that is not possible. In those cases, I try to be creative and frame and/or isolate the subject with elements of the environment, as I did with this Blue Dasher dragonfly (Pachydiplax longipennis) that I spotted last Monday at Occoquan Bay National Wildlife Refuge, the first one that I have spotted this year.

I really like this composition, despite the fact that the dragonfly is very small in the photo, thanks largely to the undulating green waves of the leaves and the out-of-focus branches in the background. What do you think? Should I have cropped the photo a bit more?

As I have noted in several recent posts, I have real troubles spotting birds when the trees are fully leafed out. In other seasons, when the trees are bare, birds tend to fly to new perches when they detect my presence and I can often track them when they are in flight and follow them visually to their new perches. Now, however, the birds seem to remain in place and sing loudly, but remain invisible to my eyes.

Last week I managed to capture an image of an American Goldfinch (Spinus tristis) when he popped into view momentarily outside of the tree canopy at Occoquan Bay National Wildlife Refuge. The little goldfinch was visible for only a short period of time, but fortunately I was looking in the right direction at that moment.

Later in the day I spotted another goldfinch perched in a distant tree. For some reason, the tree had no leaves, so it was easy for me to see the bird. I grabbed a shot and tried to move a little closer, but the bird could see my movement and immediately flew away. I hesitated to post the second photo below, because the bird is so small in the frame, but decided that I really liked the contrast between the bright yellow of the bird and the starkness of the branches and the white sky, a nice counterpoint to the lushness of the vegetation in the first photo.

As I rounded a bend in a trail last Monday at Occoquan Bay National Wildlife Refuge, I spotted a Bald Eagle (Haliaeetus leucocephalus) in the foliage of a tree right in front of me. The eagle and I both reacted instantly, but its reflexes were faster than mine and the eagle took the air. I managed to capture a few shots of the departing eagle, a testament to both my luck and a quick reaction in bringing my camera up to my eye.

The colors of the False Indigo Bushes (Amorpha fruticosa) were spectacular on Monday at Occoquan Bay National Wildlife Refuge, attracting my attention as well as that of an energetic honey bee (g. Apis) whose pollen sacs were already filled to bulging. I was initially paying so much attention to focusing on the moving bee that I did not realize that my shutter speed had dropped to 1/400—I was in aperture priority mode. The first photo was a “happy accident: in which the bee’s face was in focus, but its rapidly-moving wings were a blur.

In the second shot, the bee had landed and was crawling all around the stalks of the false indigo bush. I am really happy with my snapshot of that action that captured the color and movement of my brief encounter with the honey bee.

Later in the season I can rely on coloration to distinguish between male and female Calico Pennant  dragonflies (Celithemis elisa)—the bodies of males are red and those of females are yellow. When they first emerge, however, immature males are yellow, so you have to look really closely at a given individual to determine its gender.

The terminal appendages of the dragonfly in the second photo indicate to me that it is a male, despite the fact that its body is yellow. The one in the first photo is also an immature male Calico Pennant dragonfly that is just beginning to change from yellow to red. I love the way that he is perched on the very tip of the flimsy vegetation stalk, holding tightly to it with all of his little legs.

I spotted these two dragonflies on 12 May at Occoquan Bay National Wildlife Refuge, my first sightings of this colorful dragonfly species of the year. There is something really special about the patterned wings of both genders of Calico Pennants and when viewed from the right angle, as in the second photo, the pattern on their bodies look like a series of hearts.

During a visit on Monday to Occoquan Bay National Wildlife Refuge, I noted that many of the summer dragonfly and damselflies are starting to appear. I was particularly delighted to spot several Big Bluet damselflies (Enallagma durum). As their name suggests, Big Bluets are relatively large damselflies, with an overall length of about 1.7 inches (43 mm).

Big Bluets tend to active and a bit skittish, so it’s a bit tough to get a decent shot of one, especially when I am shooting with a zoom lens. The auto-focus of my Tamron 18-400mm zoom often has trouble focusing on a damselfly, because their bodies are so thin and they clasp their wings together over their bodies. Consequently, I frequently end up focusing manually and it is an advantage with this lens that the minimum focusing distance is 17.7 inches (45 cm), so I can get pretty close to my subject.

I was delighted to be able to capture this beautiful image of a female Big Bluet. My focusing was spot on and the background blurred out nicely. If you look closely, you may notice that the depth of field, i.e. what was in focus, was so shallow that much of the stalk of vegetation on which the damselfly was perched was out of focus. In case you are curious, I tried to position myself so that I was on a parallel plane with the damselfly’s body to get as much of it in sharp focus as possible.

One interesting factual tidbits about Female Big Bluets is that, like several other damselfly species, they come in two different color variants. This one is the blue form and there is also an olive form. What that means is that I cannot rely exclusively on the color of the damselfly to determine its species and must also look at other features like the shapes of the eyespots and markings on the terminal appendages.

The feathers of Double-crested Cormorants (Nannopterum auritum) are not completely waterproof, so periodically they have to dry out their wings. I often see cormorants completely out of the water, perched on rocks or logs with extended wings. This cormorant last week at Occoquan Bay National Wildlife Refuge apparently decided, however, that a perch was not necessary—it simply spread its wings in the air and held them in that position.

A bit earlier I captured the second image below. Usually I see cormorants in the deep waters of the bay, but this cormorant was in a small pond at the wildlife refuge. The pond is mostly surrounded by trees that are now in bloom and I was happy to capture some of the colors of the trees in their reflections on the surface of the water.

The trees are now covered with leaves, providing hiding places for the tiny songbirds that I can hear but cannot see. Fortunately, some birds are so big that it is hard to miss them, like this Wild Turkey (Meleagris gallopavo) that I spotted this past Wednesday at Occoquan Bay National Wildlife Refuge.

This turkey was slowly walking away from me and I captured this shot when he was in motion. I don’t think that a Wild Turkeys can balance themselves on a single leg when stationary, though perhaps there is a special kind of turkey yoga that enhances their balancing abilities.

Although it is relatively early in the butterfly season, this beautiful Black Swallowtail (Papilio polyxenes) that I spotted on Wednesday at Occoquan Bay National Wildlife Refuge was already beginning to show signs of the wear and tear of everyday life, with damage to its wings and body and one missing “tail.” I don’t know what caused the damage to the butterfly’s wings, but suspect that it might have been attacks by predators or collisions with thorns or other sharp vegetation.

Happy Easter to friends and family who are celebrating today. This past week has been a whirlwind of activity and services for me at my church as we have commemorated Christ’s last days, beginning with his entry into Jerusalem on Palm Sunday, through his last supper, and finally his crucifixion and burial. Today we celebrate Jesus’s triumph over death with a joyous Easter service.

I photographed this beautiful little Pearl Crescent butterfly (Phyciodes tharos) during a recent visit to Occoquan Bay National Wildlife Refuge. Butterflies have always been special for me as symbols of the amazing transformations that can take place in this world, even when the situation seems hopeless and sad.

I offer my prayers for all of you, believers and non-believers alike, that your lives will be full of joy, hope, and peace.

Christ is risen!

I was delighted to spot this Falcate Orangetip butterfly (Anthocharis midea) on 15 April at Occoquan Bay National Wildlife Refuge. The butterfly is somewhat nondescript when its wings are closed, but spectacular when they open, revealing the orange tips for which the species is named.

I encourage you to click on the second image to get a closer look at the beautiful details of this tiny butterfly, including its speckled gray eyes and wonderfully marbled wings.

I am a little late in finding my first dragonflies of 2025, but on Wednesday (15 April) I finally spotted some Blue Corporals (Ladona deplanata) at Occoquan Bay National Wildlife Refuge. As an added bonus, the first image also shows a metallic-green Six-spotted Tiger Beetle (Cicindela sexguttata) that was crawling past the dragonfly.

Blue Corporals, one of the first dragonflies to emerge in the spring, are relatively easy to identify because they have two stripes of their shoulders—two stripes is the traditional marking for the rank of corporal in the armed forces. When they first emerge, males and females have similar colorations, but the males turn blue as they mature. Judging from the shape of their terminal appendages, I believe that the dragonflies in the first two images are females and the one in the final photo is an immature male.

Earlier this season, it looked like a pair of Bald Eagles had occupied a large nest at Occoquan Bay National Wildlife Refuge. Each time that I visited the refuge, I would check the nesting site to look for indications that an eagle was sitting on eggs. Unfortunately, the nest is so deep and so high up that it is almost impossible to tell if an eagle is inside of the nest.

Last week, I watched a pair of Ospreys (Pandion haliaetus) fly into the nest and seize it and captured this shot of them doing so. Generally ospreys use much smaller, thrown-together nests, but I guess that this pair decided to advantage of what I assume is a currently unoccupied eagle nest.

As I watched the two ospreys approach the nest with dangled legs, I couldn’t help but think of the scenes from the Wizard of Oz movie in which the flying monkeys seized Dorothy. The mind works in strange ways.

Is it a bee? Is it a fly? Well, it has a fuzzy body like a bumblebee and has a long, rigid proboscis that looks like a stinger, but its patterned wings and long legs look more like those of a fly. In actuality, it is a Greater Bee Fly (Bombylius major), a parasitic bee mimic that is one of the earliest spring pollinators of wildflowers. I photographed this bee fly last week at Occoquan Bay National Wildlife Refuge.

I was quite happy to be able to capture so many of the details of this curious creature, including its long proboscis, spindly legs, patterned wings, and fuzzy body. In case you are curious, the body of one of these bee flies is about six-tenths of an inch (15mm) in length and its wing span is about one inch (25mm). I recommend that you double-click on the image to get a better look at the little details of this bee fly.

If you would like to learn more about these fascinating little bee flies, including their parasitic behavior, check out this article on the US Forest Service website by Beatriz Moisset entitled “A Pollinator with a Bad Reputation.

I was absolutely thrilled last week to spot this Zebra Swallowtail butterfly (Eurytides marcellus) at Occoquan Bay National Wildlife Refuge. Zebra Swallowtails overwinter winter in the chrysalis (cocoon) stage before emerging as adult butterflies in the spring. A second brood is born later in the year and they are the ones that lay the eggs that develop into the caterpillars that will enter into cocoons and hibernate throughout the winter.

I love the beautiful colors of this butterfly, with its zebra-like stripes and pops of red and blue—I often think of the Zebra Swallowtail as a “patriotic” butterfly, because of its red, white, and blur coloration..

This Yellow-throated Warbler (Setophaga dominica) was pretty far away when I spotted its little patch of bright yellow feathers this past Tuesday at Occoquan Bay National Wildlife Refuge. I doubted that I would be able to get a recognizable shot of it, but decided to take a chance, given that it was the first warbler that I had seen this spring. The resulting shot won’t win any contest, but I am happy that I was able to document my sighting.

Warblers pass through my area each spring at about the same time as the leaves begin to appear on the trees. It can be a bit frustrating for me to be able to hear some of these little birds without being able to see them when they are hidden in the foliage. It is a little game of hide-and-see that I play every year and this time I was able to capture a shot of one of my colorful fellow players.

I was surprised and delighted to spot this Cabbage White butterfly (Pieris rapae) as it was feeding on a newly sprouted dandelion on Tuesday at Occoquan Bay National Wildlife Refuge. I love chasing these elusive little butterflies that I used to think were moths.

Gardeners consider Cabbage Whites to be pests, because their caterpillars can do significant damage to plants, including cabbage, broccoli, cauliflower, and collard greens, but I find them to be beautiful. In that respect I guess I am a kind of dreamer who prefers to focus more on form than on function.

Long telephoto lenses tend to distort your depth perception. On Tuesday I watched this North American Snapping Turtle (Chelydra serpentina) swimming about in a pond at Occoquan Bay National Wildlife Refuge. I was a bit creepy as the turtle got bigger and bigger in my viewfinder when it began to swim directly towards me. One part of my brain objectively knew that the turtle was still a long way off, but it was nonetheless a bit disconcerting when the snapping turtle’s dinosaur-like eyes appeared to be staring right at me.

Spring is here, though the weather has been cool recently and there were some local frost warnings last night, and all kinds of creatures are waking up. I’m still looking for my first dragonfly of the year and will probably continue my quest later today.

I have been hearing a lot of Red-winged Blackbirds (Agelaius phoeniceus) during recent visits to Occoquan Bay National Wildlife Refuge and was delighted to finally capture a shot of one last week that shows the distinctive yellow and red shoulder patch of the males of his species.

I was hoping that the blackbird would fly to some lower branches, but he seemed content to perch high above me in a tree. I was pleased, though, to be able to capture this fun little portrait—it is tough to convince birds to pose for me.

In some locations the reappearance of Eastern Phoebes (Sayornis phoebe) is one of the first indications that spring is returning. I am not sure if Eastern Phoebes are with us year round in Northern Virginia, but I know that it as been quite a few months since I last saw one.

On Tuesday I spotted this phoebe in a tree at Occoquan Bay National Wildlife Refuge. Branches were partially blocking my view of the bird, but I managed to find get a clear view of its face (and most importantly of its eye) by making small adjustments to my shooting position.

I was delighted to spot this Brown Thrasher (Toxostoma rufum) last week at Occoquan Bay National Wildlife Refuge. I had to move around a lot to get a clear view of its head, though I was pretty sure it was a thrasher when I caught a glimpse of its bright yellow eye and long tail. The Cornell Lab of Ornithology did a great job in describing the challenges of spotting this species, “It can be tricky to glimpse a Brown Thrasher in a tangled mass of shrubbery, and once you do you may wonder how such a boldly patterned, gangly bird could stay so hidden.”

Brown Thrashers are present year round in the southern portions of Virginia, but I think they move north into my area of Northern Virginia during the breeding season. Before long we should have lot of other birds, including warblers, migrating through our area and, of course, dragonflies and other insects will soon reappear. Yesterday  i noted a posting in Facebook with photos of dragonflies that were recently taken in central Virginia. I will probably venture out later today to see if I can spot any dragonflies myself.

Osprey (Pandion haliaetus) are very opportunistic birds—they will make a nest almost anywhere there is a bit of space. Last week I spotted an osprey perched on the roof of a duck blind in the water and captured this cool little image.

These little shack-like structures on stilts have been built in the waters off of Occoquan Bay National Wildlife Refuge and are used a few weeks a year during duck hunting season. It is a little disconcerting during that time to hear shotguns being fired only a short distance away, but the money collected for hunting licenses is used for waterfowl habitat improvement and restoration in Virginia.

Buds are beginning to grow on many of the trees in my area as we welcome the beginning of spring.  However, it looks like this little Carolina Chickadee (Poecile carolinensis) that I spotted on Tuesday at Occoquan Bay National Wildlife Refuge was impatient and chose to nibble on a tender young bud that had barely started to develop.

The lighting conditions were not optimal, but I like the way that I was able to capture the way that the chickadee used its tiny bill to poke into the underdeveloped bud. It may not seem like much, but I suspect that the chickadee welcomed the taste of the tender spring bud after a long winter of gnawing on hard, wizened seeds.

Something attracted the attention of this Osprey (Pandion haliaetus) on Tuesday at Occoquan Bay National Wildlife Refuge and it kept looking down at the ground. At first I thought that the osprey had caught a fish that it was trying to protect from competitors, but when I zoomed in, I did not see any fish.

Perhaps the osprey was looking for its mate or was merely curious to observe all the things that were going on. I don’t think that the osprey had spotted me when I took these shots, but that is also a possibility.

When Great Blue Herons (Ardea herodias) take off from the water, they really stretch out and usually I cut off part of their bodies when trying to photograph them in action. Last week, though, my timing was good and I captured this little sequence of images as a heron took to the air, flew for a short distance, and “stuck” its landing in the water.

I was really happy with the way that I was able to capture so many details, from the arc of the water droplets as the heron rose out of the water to the bird’s different-colored feathers. In the final photo, the spread wings, wind-blown “hair,” and the wonderful reflection combine to create a really cool mood in the image.

I don’t know if thegroup of Painted Turtles (Chrysemys picta)) was a family unit or merely good friends, but they seemed to be cooperating to maximize their exposure to the warmth of the sun last week at Occoquan Bay National Wildlife Refuge. At some of the other wildlife parks in my area there are large logs on which the turtles will space themselves out as they bask in the sun, but flat dry land is limited at this refuge, so the turtles are willing to share the space with others.

As I was taking the first photo, several more turtles emerged from the pond, as you can see in the second photo below. Their wet shells are much darker than those of the first three turtles that have had a chance to dry out a bit.
