Halloween Pennant on gamagrass

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , , on August 26, 2023| 2 Comments »

Last Monday I spotted this striking female Halloween Pennant dragonfly (Celithemis eponina) perched high in the eastern gamagrass (Tripsacum dactyloides) at Occoquan Bay National Wildlife Refuge. It was somewhat unusual for me to have a chance to photograph a dragonfly above eye level and I did my best to isolate the subject against the pale blue sky.

I really like the minimalism of this composition.  The color and texture of the gamagrass add some visual interest to the image without distracting the viewer from the primary subject.

Eastern Tiger Swallowtail butterfly

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 25, 2023| 4 Comments »

I was excited to spot this beautiful Eastern Tiger Swallowtail butterfly (Papilio glaucus) on Monday at Occoquan Bay National Wildlife Refuge. Most years I spot lots of these butterflies, but for some reason I have not seen one in quite some time this summer.

I love the beautiful coloration of this Eastern Tiger Swallowtail and believe that it is a female. Males of this species are almost exclusively yellow and black, while females are more vividly colored, with strongly pronounced cells of orange and a greater degree of iridescent blue on the lower wings.

Which photo is best?

Posted in Art, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , , , on August 24, 2023| 9 Comments »

When I am writing a blog posting with multiple photos, I will usually lead with the “best” photo. Most of the time I have a clear favorite image, but today I struggled a bit in trying to decide which image of a Calico Pennant (Celithemis elisa) was the “best” one. I was delighted on Monday at Occoquan Bay National Wildlife Refuge to have multiple opportunities to photograph male Calico Pennants, which are among the most striking dragonflies that I encounter, thanks to their bold coloration and wonderfully patterned wings.

From a technical perspective, the first image could be considered the “best.” The background is pleasantly blurred and virtually all of the dragonfly’s features are in sharp focus. Graphically this image stands out, even when viewed as a thumbnail on a cell phone.

The background in the second image is considerably more cluttered than in the first image. However, I think the color contrast between the bright red of the dragonfly and the pinkish-purple colors in the background makes it easy to see the primary subject. The vegetation helps to provide the viewer with a sense of the environment in which I photographed the dragonfly.

The third image was the most challenging to capture. Several Calico Pennants were flying around over the waters of a pond and I was thrilled to capture this in-flight shot, my first such photo of this species. Most of the other dragonflies that I have photographed as they were flying were considerably larger—a Calico Pennant is only about 1.3 inches (33 mm) in length—and it took a lot of persistence and concentration to get this shot.

The final shot was a lucky one. I was focused on the perched dragonfly and reacted quickly when it took off. From an artistic perspective, I really like this image. The mottled colors of the pond works well as a backdrop for the action and the contrast between the muddy brown and the bright red of the dragonfly makes the subject “pop.” I love the texture of the branch and the branch helps to lead the viewer’s eyes to the dragonfly. Finally, the dragonfly’s wing patterns are displayed beautifully as I managed to capture a moment when they were fully extended.

I don’t know if it is possible for me to state definitively which one of these images is the “best”—I like each of them for different reasons. Is there one that stands out to you more than the others? I’d welcome your views on this question.

Black Vultures

Posted in Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 23, 2023| 7 Comments »

The gloomy feel of this photo seems perfect for these two Black Vultures (Coragyps atratus) that I spotted in a dead tree on Monday at Occoquan Bay National Wildlife Refuge. Many people find vultures to be creepy, probably because they feed on the carcasses of dead animals. I remember too watching cowboy movies when I was growing up in which vultures would be circling overhead, waiting for people to die in the desert wastelands.

There were lots of vultures circling overhead on Monday and in situations like that, I jokingly tell people that I try to move about a lot, lest the vultures mistake me for a potential meal.  In my area, we have both turkey vultures and black vultures. They are pretty easy to tell apart, because turkey vultures have very distinctive red heads and black vultures have black heads. According to the Cornell Lab of Ornithology, “Whereas Turkey Vultures are lanky birds with teetering flight, Black Vultures are compact birds with broad wings, short tails, and powerful wingbeats. The two species often associate: the Black Vulture makes up for its poor sense of smell by following Turkey Vultures to carcasses.”

The light was coming mostly from behind the two birds, which created the silhouette-like effect that you see in the image below. I lightened the shadows a little, but I like the starkness of the almost monochromatic view of these birds in which most of their details are suggested, but hidden. I think it works well with the simple structure of the branches of the dead tree. Unlike most of my images that concentrate on detailed views of my subjects, this image is more about mood and shapes.

Big Bluet damselfly

Posted in damselfly, Insects, Macro Photography, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 22, 2023| 8 Comments »

Yesterday it was hot and humid and there was an air quality alert because of smoke from the Canadian wildfires. I was therefore not too surprised when I pulled into the parking lot at Occoquan Bay National Wildlife Refuge to see that I was the only car there. As I have mentioned previously, I prefer to enjoy nature alone whenever possible, so I was quite pleased that I had the refuge to myself.

It was about midday, so I knew that the birds would not be very active—they tend to be more active in the early morning and later afternoon—but I knew that many insects prefer the warmest periods of the day. I saw quite a few Big Bluet damselflies (Enallagma durum) in the vegetation near the water. As its name suggests, this damselfly is quite large—up to 1.7 inches (43 mm)—and is primarily a coastal species.

This was my favorite shot of the day of a Big Bluet. I like the overall cool tones of the image and the way that the vegetation fades into background, allowing the viewer to focus on the wonderful details of this beautiful Big Bluet.

Slaty Skimmers

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on August 16, 2023| 2 Comments »

One of the most common dragonflies that I see at this time of the year is the Slaty Skimmer (Libellula incesta). Male Slaty Skimmers have dark bodies and dark eyes and are pretty easy to identify. Slaty Skimmers tend to perch on bare stalks and one of my challenges in photographing them is to try to frame my shots so that the background is interesting.

Here are three images in which I tried to use a bit of my creativity in the way that I composed the shots by including some of the vegetation, as in the first and second shots, or by focusing on lines and angles, as in the final photo.

I am making another trip this week to Massachusetts and Maine to deal with some family issues, so this may be my last blog post of the week. I am planning to return on Saturday, so perhaps there will be a new posting on Sunday morning.

Juvenile Ospreys

Posted in Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 10, 2023| 1 Comment »

Two juvenile Ospreys (Pandion haliaetus) appear to almost grown up, but I believe they are still dependent on their parents to feed them. They made protracted cries of what appeared to be “Feed me” when they spotted an adult osprey flying in the distance last Saturday at Occoquan Bay National Wildlife Refuge.

Sometimes their movements seemed synchronized, as in the first photo, but at other times they expressed themselves in individual ways. In the second photo, you may notice that the two ospreys have speckled feathers and orange eyes, two signs that they are not yet adults, which have dark feathers and yellow eyes.

Male Needham’s Skimmer dragonfly

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 8, 2023| Leave a Comment »

Last Saturday morning at Occoquan Bay National Wildlife Refuge I was delighted to spot this male Needham’s Skimmer (Libellula needhami), one of the most brightly colored dragonflies in our area. In addition to its beautiful reddish-orange color, this dragonfly has stunning gold accents on the front edges of each of its wings.

Skipper and Milkweed

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 7, 2023| 1 Comment »

The milkweed flowers were just beginning to open, but this Silver-spotted Skipper (Epargyreus clarus) was already attracted to it. I spotted this butterfly, one of the only skipper butterflies that I can reliably identify, on Saturday during a short visit to Occoquan Bay National Wildlife Refuge. Usually I avoid visiting locations like this on the weekend, because they tend to be too crowded for my taste—I am a little selfish when it comes to sharing my wildlife experience with others and generally prefer a solitary pursuit.

Some other local photographers have already spotted some warblers, so I had my long 150-600mm lens on my camera when I encountered this butterfly. I am pretty happy with the amount of detail that I was able to capture with the lens fully extended—this lens has a reputation of being quite soft at the long end, but that has not generally been my experience.

Blue-gray Gnatcatcher

Posted in Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 5, 2023| 3 Comments »

Most of the time I hesitate to take photos of birds head-on, because the bills and other facial features can look distorted. However, I really like this image I captured of a jaunty little Blue-gray Gnatcatcher (Polioptila caerulea) during in visit in July to Occoquan Bay National Wildlife Refuge.

Blue-gray Gnatcatchers are tiny songbirds, about four inches (10 cm) in length, and are only slightly larger than Ruby-throated Hummingbirds. Their tails are really long and dark with white outer tail feathers. In this image, the tail is angled to the side—at first glance it almost looks like the green leaf behind the gnatcatcher’s head is the tail.

It is always hard to interpret the facial expressions of birds. At first I thought the expression in this photo was one of confrontation, but increasingly I have come to the conclusion that it more likely was one of curiosity.

In case you are curious, the gnatcatcher was in a shaded area, so I had to increase the exposure to try to pull the bird out of the shadows. The increased exposure caused the sky in the background to turn white.

Bald Eagle in mid-July

Posted in Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 23, 2023| 12 Comments »

I have gotten so caught up in posting photos of insects and flowers, that I nearly forgot that I had managed to capture this shot of a Bald Eagle (Haliaeetus leucocephalus) a week or so ago during a visit to Occoquan Bay National Wildlife Refuge. I have a really problem spotting small birds because of the abundance of leaves on the trees, but this eagle cooperated by perching in the open on a branch where he was quite visible.

At certain times of the year I worry about oversaturating my blog with photos of eagles, but numerous readers have told me that they never get tired of seeing eagles. My oft-stated view is that any day that I spot a bald eagle is a good day.

Personally, I hold the same view about I dragonflies, which is why they appear in this blog more often than any other creatures during the warm months of the year.

Another Monarch butterfly

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 15, 2023| 2 Comments »

Recently I featured some shots of a Monarch butterfly (Danaus plexippus) feeding on some milkweed. I feared that it might be the only Monarch that I would see this year, because there have been some years in the recent past when I have not spotted a single Monarch butterfly.

I was absolutely delighted this past Wednesday when I spotted another Monarch. I was walking along one of the trails at Occoquan Bay National Wildlife Refuge when my eyes were attracted by a flash of bright orange. I assumed incorrectly that it was “only” a Viceroy, but when I zoomed in, I could see that it was a Monarch.

I was using my long 150-600mm lens with a monopod, so I had to scramble a bit to get a good shooting angle. I was thrilled with the shot that I captured of the Monarch in action with its proboscis extended. I am not sure what kind of flower this is, but I really like the way that it was drooping a little as the butterfly perched lightly on it, helping to create a nice triangular composition.

Osprey babies

Posted in Baby photography, Birds, Nature, Photography, Summer, wildlife, tagged , , , , , , , on July 14, 2023| 4 Comments »

For the first time in a month or so, on Wednesday I put my 150-600mm zoom lens on my camera in place of my trusty 180mm macro lens and visited Occoquan Bay National Wildlife Refuge. Rather than focusing on insects, as I have been doing since early spring, I decided to try to get some shots of birds. Several local photographers have recently posted photos of the juvenile bald eagles at the wildlife refuge that are now much larger that when I saw them last and I was hoping that I might have a chance of seeing them myself.

As it turned out, I did not see the juvenile eagles that day, but I did catch a glimpse of at least two Osprey babies (Pandion haliaetus) that were in the nest with one of their parents. I don’t know how old the little ospreys are, but they seemed curious and energetic. One of them stretched out his wings a bit while I was watching, but the babies don’t appear to ready to fly on their own quite yet.

The rather loosely constructed nest has branches sticking out in all directions that often blocked my view of the trio of ospreys and this is one of the few photos that I took in which I had a clear view of all three of their faces. I did not have very much luck getting photos of other birds that day, many of which I could hear but could not see amidst the abundant foliage.

Calico Pennant dragonflies

Posted in Dragonflies, dragonfly, Insects, Macro Photography, Nature, Photography, spring, wildlife, tagged , , , , , , on May 17, 2023| 5 Comments »

I was delighted last Thursday to see quite a few Calico Pennant (Celithemis elisa) dragonflies during a visit to Occoquan Bay National Wildlife Refuge. The markings and wing patterns on this species are really striking, making this one of the most attractive species that I see during the dragonfly season.

Some of the Calico Pennants appeared to have newly emerged—when dragonflies initially break through the exoskeleton of their water-dwelling larvae selves, their wings are really shiny and fragile and their coloration is often pale. The dragonfly in the first photo appears to be in that stage of development, which is sometimes referred to as “teneral.” It you look closely at the place where the dragonfly is grasping the vegetation, you can see what is quite probably its discarded exoskeleton from which it had recently emerged.

The Calico Pennants in the second and third photo are females, as was the one in the first photo. The patterns on the wings of these more mature females are more distinct and their yellow coloration is somewhat brighter. How do I know that they are females? If you look closely at the ends of their abdomens (the “tails”) you can see the terminal appendages that indicate their gender.

Female Calico Pennants have yellow markings on their abdomens, but that is not a reliable indicator of their gender, because immature males have that same coloration. The dragonfly in the fourth photo, for example, is an immature male Calico Pennant. If you compare the tip of the abdomen of this dragonfly with the one in the third photo, you may be able to see that there are differences.

What does a mature male Calico Pennant look like? I managed to spot only a single mature male that day, but fortunately was able to capture a shot of it. As you can see in the final photo, adult male Calico Pennants have red marking on their abdomens and the veining on their wings is pinkish in color.

We are gradually transitioning to the summer dragonfly species and some of the early spring ones are starting to disappear. I’ll be keeping my eyes open for the “new” species, so don’t be surprised to see more dragonfly photos in the upcoming months.

Tweety Bird

Posted in Birds, Nature, Photography, Portraits, spring, wildlife, tagged , , , , , , , , on May 16, 2023| 10 Comments »

I love the poses of this bright yellow Prothonotary Warbler (Protonotaria citrea) that I spotted last Thursday at Occoquan Bay National Wildlife Refuge. The warbler was actively twisting, turning, and stretching as it foraged for food and amazingly was perched quite low in the vegetation—most of the times in the past I have seen Prothonotary Warblers high in the trees and was forced to shoot them from an unflattering sharp upward angle.

Quite often when I am focusing on a wildlife subject, it moves. Most of the time the result is a blurry image, but sometimes I end up with a really cool shot. The Prothonotary Warbler took off just as I pressed the shutter release and I was lucky to capture it in action, as you can see in the final photo.

The yellow plumage of a Prothonotary Warbler is startlingly bright and cheerful. Invariably the sight of a Prothonotary Warbler makes me think of Tweety Bird, a character from Warner Brothers Looney Tunes cartoons that I remember from my childhood. I think that Tweety was supposed to be a canary, but he didn’t really look like a canary. Often Tweety had adventures with Sylvester the cat, the subject of Tweety’s signature line, ” “I tawt I taw a puddy tat!””

Great Blue Heron in a tree

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , on May 15, 2023| 5 Comments »

As I was scanning the trees for small birds last Thursday at Occoquan Bay National Wildlife Refuge, I spotted this Great Blue Heron (Ardea herodias) surveying its surroundings from its high perch. I have occasionally seen herons roosting in the trees in the past, but it has usually been earlier in the day—this heron might have decided that it wanted a mid-afternoon nap or at least a few peaceful moments.

Now that I am retired, I have rediscovered the pleasure of naps and a Sunday afternoon nap has become part of my weekly routine.

An eaglet at last

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , on May 14, 2023| 1 Comment »

I patiently watched the large Bald Eagle (Haliaeetus leucocephalus) nest last Thursday at Occoquan Bay National Wildlife Refuge and eventually caught a glimpse of an eaglet. As some of you may recall, I have been keeping an eye on three eagle nests at this refuge and have already seen eaglets at the other two nests. This nest is significantly larger than the other two nests, as you can see in the second photo, and it is difficult to see activity in the nest.

I was zoomed in as close as I could with my telephoto lens and still had to crop the image in the first photo quite a bit so you can see the eaglet with its open mouth—I suspect it wanted to be fed. As you can see, one of the parents was in the nest with the eaglet and the other parent was perched in a nearby tree. It is possible that there are more eaglets in the nest, but I was really happy to spot one.

In case you are curious, I did not have my longest telephoto lens with me that day. Normally I use my Tamron 150-600mm lens when I know that I will be photographing birds. I was anticipating that I would be focusing on both large and small creatures, so I was using my Tamron 18-400mm lens on this occasion.  This lens gives me a great deal of flexibility in photographing dragonflies as well as birds and in capturing landscape shots like the shot of the nest—I was standing in the same spot for both photos in this blog posting.

Singing Prairie Warbler

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , on May 13, 2023| 3 Comments »

On Thursday I was blessed to photograph a beautiful little Prairie Warbler (Setophaga discolor) as it was singing in a small tree at Occoquan Bay National Wildlife Refuge. At this time of the year I can often hear the birds, but have trouble spotting them amidst the abundant foliage. Even when I am able to locate a warbler, it is usually perched really high in a tree, out of range of my telephoto lens. In this case, the warbler was almost at eye level when I took these photos.

Despite its name, the Prairie Warbler is not found on a prairie. According to the Cornell Lab of Ornithology, “Finding this bird during the breeding season is often as simple as finding the scrubby second-growth forests, young pine stands, and overgrown pastures that it prefers. In spring, listen for males singing from a mostly exposed perch in one of the tallest trees in its territory, a distinctive sputtering buzz that starts low and climbs high up the scale, beyond human hearing.”

Looking at you looking at me

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , on May 10, 2023| Leave a Comment »

As I was observing a large nest last Friday at Occoquan Bay National Wildlife Refuge, I couldn’t help but notice that the Bald Eagle (Haliaeetus leucocephalus) in the nest was keeping an eye on me. The eagle seemed to be observing me through a gap in the branches at the top of the nest, as you can see in the first two photos.

After getting a few shots, I continued walking down the trail. When I looked back towards the nest, I could see the eagle’s head poking out of the top of the nest and it still seemed to be watching me.

As you can tell from the final photo, this is a really large nest and it is hard to monitor what is going on inside of it. Are there any eaglets yet? In two other nests at the refuge, I have already seen eaglets, but those nests were much smaller, so it was not hard to spot the babies. I’ll continue to monitor this nest and with a little luck I will see an eaglet or two in this large nest.

Acrobatic Warbler

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , on May 9, 2023| 7 Comments »

It was fascinating to watch this acrobatic little Prothontary Warbler (Protonotaria citrea) last Friday as it twisted and turned, poked and probed while searching for tasty treats among the leaves of a tree at Occoquan Bay National Wildlife Refuge. We have reached a time of the year when most of the small birds are hidden by the leaves on the trees, so I was really fortunate to be able to spot this warbler and to track it as it moved about in this tree.

Turkey and bunny

Posted in animals, Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , , , on May 8, 2023| 4 Comments »

Although it is fun to try to photograph migratory species passing through our area, I am equally content to photograph the local species that are present throughout the year, like Wild Turkeys and Eastern Cottontail Rabbits. This rather rotund Wild Turkey (Meleagris gallopavo) seemed to be dancing the hokey-pokey when I spotted it last Friday at Occoquan Bay National Wildlife Refuge. “You put your right leg in, you put your right leg out. You put your right leg in and you shake it all about…” For the record, I did not join in the dance.

Later that same day I encountered this cute little Eastern Cottontail Rabbit (Sylvilagus floridanus). The rabbit was quite tolerant on my presence and calmly chewed on the grass while I took its picture. For several years I cared for a pet rabbit, so rabbits have a special place in my heart.

Turkeys and rabbits are quite common at this refuge and at certain times of the day I am likely to encounter them. Generally they slowly move into the undergrowth as I approach. I don’t think they necessarily view me as a threat, but they probably do not want to take chances.

Eaglet tests its wings

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , on May 7, 2023| 2 Comments »

This juvenile Bald Eagle (Haliaeetus leucocephalus) may not be quite ready to fly, but it was testing out its wings by flapping them vigorously while I was observing the nest on Friday at Occoquan Bay National Wildlife Refuge. The eaglet is so large that there is no longer any room in the small nest for its parents—one of its parents was perched on a higher branch in the same sycamore tree.

A few weeks ago, I observed two eaglets in this nest and I have not had a good look at both eaglets since that time. Has something happened to the other eaglet? When I looked closely at all of my photos, I noticed that I could see the silhouettes of both eaglets sitting side by side in some of the images, as you can see in the final photo. The eagle on the left seems much smaller than the one on the right, which was the one that was flapping its wings in the first two photos.

The foliage in the tree and the barrier across the trail keep me from seeing any better what is happening in this eagle nest, but it looks like the eaglets are growing bigger and stronger, especially the one on the right. It should not be too long before it is time for the eaglet to be making its first tentative attempts at flight.

Ospreys

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , on May 5, 2023| 2 Comments »

There are now plenty of Ospreys (Pandion haliaetus) to see at Occoquan Bay National Wildlife Refuge, though it is still a challenge to get a decent shot of one. I spotted the osprey in the first photo last week and it seemed to be in a pensive mood or perhaps was simply alert to the possibility of an attack from above. One of my Facebook readers suggested that this was an osprey father-to-be who was contemplating the weight of his new responsibilities and the end of his happy-go-lucky bachelor days.

The osprey in the second shot was keeping watch over one of the larger osprey nests at the wildlife refuge. Unlike bald eagles, which put a lot of care and attention into the construction of their nests, ospreys often seem content to throw a few sticks together in a rather haphazard way. As a result, quite a few osprey nests are damaged by winter storms and have to be reconstructed when the ospreys return in the spring.

The osprey in the final shot is working on a different nest. Ospreys lay their eggs later than the eagles, which are already caring for their young eaglets. It is probably about time now for the ospreys to begin sitting on their nests and incubating their own eggs.

Tiny butterfly

Posted in Butterflies, Insects, Nature, Photography, spring, wildlife, tagged , , , , , , on May 4, 2023| 8 Comments »

I was happy that I managed to get a shot of this tiny butterfly perched low in the vegetation at Occoquan Bay National Wildlife Refuge on Wednesday. I think it may be a Falcate Orangetip (Anthocharis midea), although the butterfly never opened its wings, so I was not able to confirm that the wings were tipped with orange.

I was a bit shocked that I was able to capture so much detail of this tiny creature, given that I was shooting with my Tamron 150-600mm zoom lens fully extended to 600mm. When I bought this lens in November 2014, I remember reading reviews about the lens that stated that it was soft at 600m. That has not really been my experience. If I pay attention to my techniques and use a monopod for additional stability (as I was doing for this shot), I can shots that are acceptably sharp to my eye.

For those of you who are especially geeky, for this shot I was shooting with a Canon 7D at f/8, 1/400 sec, and ISO 800 with an exposure compensation value of minus 1.33 stops. More important than the settings, though, is the fact that I like the image that I managed to capture—that is always my number one priority.

Varying backgrounds

Posted in Dragonflies, dragonfly, Macro Photography, Nature, Photography, spring, wildlife, tagged , , , , , , , , , on May 3, 2023| 2 Comments »

As I was reviewing my photos of the past couple of weeks, I was a little surprised at the number of shots that I have taken of Blue Corporal (Ladona deplanata) dragonflies in wildly varying environments. Blue Corporals are an early-season species and won’t be around for too much longer, so I am happy to have had the opportunity to observe so many of them. Most of the time, Blue Corporals like to perch flat and, judging from the photos, it doesn’t seem to matter if there are rocks, vegetation, or even lily pads.

From the perspective of a naturalist, I like the way that the different photos give you a feel for the environments in which I found these dragonflies. As a photographer, I was also struck by the way that the colors and textures of the background interact with the subjects. Most of the backgrounds in these shots are somewhat cluttered, but I did my best to use framing and focusing techniques to keep the background from being too distracting.

If I had to make a choice, I would say that the first photo is my favorite of the Blue Corporal images. I love the juxtaposition of the dragonfly with the varied textures, shapes, and colors of the rocks. I also really like the way the background grows progressively more blurry towards the top of the image. Do you have a favorite?

King of the hill

As I was focusing in on a Tree Swallow (Tachycineta bicolor) that was happily singing from a perch sticking out of a small pond, another swallow came screeching in in an attempt to take over the perch. The attack was successful and the first bird was forced to leave.

Happy with his effort to become “king of the hill,” the new swallow began to sing with all of his might as he surveyed his new kingdom. How long will his reign last? Undoubtedly the swallow knows that others may soon seek his place, but seems determined to enjoy his moment in the spotlight.

Common Baskettail dragonfly

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, spring, wildlife, tagged , , , , , , on May 1, 2023| 8 Comments »

I tracked this Common Baskettail dragonfly (Epitheca cynosura) in the air for quite some time as it patrolled back and forth along one of the trails at Occoquan Bay National Wildlife Refuge, hoping that it would land. Fortunately I acted quickly when finally it did perch and was able to capture these shots.

The Dragonflies of Northern Virginia website provides the following description of the Common Baskettail, “Small, dark, constantly hovering. Fast, acrobatic flight. Often high above clearings and sunny paths/old roads. Also along pond, stream and river edges.” As you can tell from this description, it is pretty challenging to get a shot of a Common Baskettail dragonfly.

Occasionally I will try to capture an image of a Common Baskettail while it is flying, but that works better when the dragonfly is flying above a pond than when it is flying with a background of vegetation. If you are interested in seeing some shots of Common Baskettails in flight, check out my blog posting from May 2022 entitled “Flying Common Baskettail dragonflies.”

Impassive eagle

Posted in aircraft, Birds, Nature, Photography, spring, wildlife, tagged , , , , , , on April 29, 2023| 8 Comments »

This Bald Eagle (Haliaeetus leucocephalus) remained steadfastly on guard above its large nest on Wednesday at Occoquan National Wildlife Refuge as a jet flew by in the distance. As I was focusing on the eagle, I caught sight of the jet out of the corner of the eye and managed to time the shot pretty well to be able to include the jet in the frame.

Normally I do not like to include man-made objects in my wildlife photos, but in this case I really like the juxtaposition between the wildness of a bald eagle’s flight and the more “civilized” human flight.

Eaglet update

Posted in Baby photography, Bees, Nature, Photography, spring, wildlife, tagged , , , , , , , on April 28, 2023| 6 Comments »

On Wednesday I visited Occoquan Bay National Wildlife Refuge to check on the eaglets in the nests there.  As the leaves continue to grow, it is becoming harder and harder to observe activity at several of the nests of the Bald Eagles (Haliaeetus leucocephalus). In one of them, though, I managed to find a small visual tunnel and was fortunate to capture the first two images that show some sweet little moments between an eaglet and one of its parents.

The third image shows an eaglet in a different nest. As you can see, the leaves on the sycamore tree hid most of the nest. Previously I spotted two eaglets in this nest, so there may be another hiding out of view.

The final two shots shows the largest eagle nest at the refuge. The nest is so big and so high in the trees that it is difficult to tell what is going on inside of the nest. One eagle was keeping watch and the other adult appears to be in the nest. If you look closely at the nest right below the tree on which the eagle is perched, you can just make out the yellow beak of an adult eagle. The final image is a close-up shot of the nest that I cropped to show more clearly the eagle’s beak. The adult eagle is perched so high in the nest that it is possible that there is an eaglet or two in the nest as well—when an eagle is incubating eggs it tend to hunker down really low to keep the eggs warm.

Depositing eggs in the water

Posted in Dragonflies, dragonfly, Nature, Photography, spring, wildlife, tagged , , , , , , , on April 27, 2023| Leave a Comment »

It is pretty early in the season for Common Whitetail dragonflies (Plathemis lydia), but one pair was already getting busy last Friday at Occoquan Bay National Wildlife Refuge. I did not see the actual mating taking place, but I captured this first shot as the female deposited eggs in the water as the male hovered overhead. The second image is a distant shot of the hovering male Common Whitetail.

Different dragonfly species deposit their fertilized eggs in different ways. Some will place the eggs directly into vegetation, while others distribute their eggs more generally into the water. Female Common Whitetails are in the latter group—they oviposit in flight, with guarding male hovering above, by tapping their abdomen into the water near floating vegetation or clumps of mud and often flicking water and eggs forward. According to

If you look closely at the first photo, you can see some concentric ripples where the dragonfly has dipped the tip of her abdomen in the water, releasing some eggs and creating some disturbance on the surface of the water. The male’s job is to fight off any potential rivals that might try to interfere with the process and mate with the female.

The eggs will develop into larvae that will spend most of their lives underwater. The adult phase of their lives, when they transform into dragonflies, may last only a few weeks or so, which is why perpetuation of the species through mating is such a critical biological imperative.

Black Swallowtail butterflies

Posted in Butterflies, Insects, Nature, Photography, spring, wildlife, tagged , , , , , , on April 24, 2023| 3 Comments »

One of the clear signs that we are moving through spring is the emergence of large numbers of full-sized butterflies. Last week I was delighted to spot multiple Black Swallowtail (Papilio polyxenes) butterflies. Dark swallowtail butterflies can sometimes be problematic for identification, because in our area we have Pipevine Swallowtails, Spicebush Swallowtails, and the dark morph female Eastern Tiger Swallowtail, in addition to the Black Swallowtail.

However, these butterflies were relatively easy to identify, because I could clearly see the black dot inside the orange dot in each of the photos, one of the field markers of a Black Swallowtail. I was quite struck by the unblemished state of each of these butterflies, which seemed to be fresh and bright with fully intact swallowtails. As the season moves on, some of the butterflies will become more and more tattered and faded.

If you are curious about the identifying marks for the different kinds of dark swallowtails, I highly recommend a blog posting by Louisiana Naturalist called Four Dark Swallowtails. In this posting, she does side-by-comparisons of the four species from different angles and points out the visible differences that are really useful in identification.
