Hummingbird Moth and Thistle

Posted in Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 8, 2021| 8 Comments »

The thistle flowers at Occoquan Bay National Wildlife Refuge again turned out to be irresistible to insects. Previously I photographed several butterfly species gathering nectar from the thistle—see my recent posting Butterflies and Thistle). This past Friday, a Hummingbird Clearwing Moth (Hemaris thysbe) flew by me as I was approaching a thistle patch and I managed to snap off a few photos before it flew away.

I love how the first photo shows the transparency of the wings of this beautiful insect. My camera shutter speed for the shot was 1/2000 second, which was fast enough to freeze all of the wing motion as the moth hovered in the air. It is cool how clearly you can see the thistle through those clear wings.

The second image, which was actually taken before the first one, shows the moth as it was first approaching the thistle. I believe that it was just beginning to unfurl its long proboscis, which it extends to suck out the nectar and then curls up tightly when it is flying.

Wandering Glider in September

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 7, 2021| 9 Comments »

I was absolutely thrilled last Friday to photograph a Wandering Glider dragonfly (Pantala flavescens) while I was wandering the trails at Occoquan Bay National Wildlife Refuge. Wandering Gliders, also know as Globe Skimmers or Globe Wanderers, are considered to be the most widespread dragonfly on the planet, with a good population on every continent except Antarctica, although they are rare in Europe, according to Wikipedia. Wandering Gliders make an annual multigenerational journey of some 11,200 miles (about 18,000 km); to complete the migration, individual Wandering Gliders may fly more than 3,730 miles (6,000 km)—one of the farthest known migrations of all insect species.

As their name suggests, Wandering Gliders are one of those species that like to patrol endlessly in the sky, rarely stopping to perch. When I first spotted this Wandering Glider it was flying back and forth overhead and my neck grew tired as I tried to track it visually in the air. It fooled me a couple of times when it flew low over a patch of vegetation and I thought it might stop for a moment, but it continued to fly. Eventually it landed and perched, hanging at a slight angle from a broken-off branch about a foot (30 cm) off of the ground.

A Wandering Glider is a fairly compact dragonfly at about 1.9 inches (48 mm) in length, but as you can see in the photo, it has long, broad wings. For comparison purposes, Black Saddlebags dragonflies, which I featured last week, are a bit bigger at 2.2 inches (55 m), and Common Green Darners, another migratory dragonfly species, are even larger at up to 3 inches in length (76 mm).

Swallowtail in September

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 6, 2021| 18 Comments »

It is always special to get a shot of a Zebra Swallowtail butterfly (Eurytides marcellus). Normally they are in constant motion, rarely perching for more than a split second. I spotted this one on Thursday at Occoquan Bay National Wildlife Refuge and was struck by its pristine condition—so many butterflies that I see at this time of the year are tattered and faded, but still surviving.

I suspect that this one butterfly might have only recently emerged. According to information from the Maryland Biodiversity Project, Zebra Swallowtails in this area fly in several broods, from mid-April, early July, and again in early September.

Male Calico Pennant

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 5, 2021| 15 Comments »

I was delighted on Thursday at Occoquan Bay National Wildlife Refuge to see that the Calico Pennant dragonflies (Celithemis elisa) are still with us. Now that we have entered into September, I have begun an unofficial countdown for each species. Every encounter is now even more special, because oI am conscious that it coule be the last one of this dragonfly season.

A couple of weeks ago I featured a beautiful yellow-bodied female Calico Pennant dragonfly (see the posting Female Calico Pennant from 24 August if you need to refresh your memory of this delicate creature). Today I am spotlighting an equally stunning male Calico Pennant. I absolutely love the multi-colored pattern on his hind wings and the bright red markings on his body—the red markings look like a series of little hearts when viewed directly from above.

Perching Black Saddlebags

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged , , , , , , on September 4, 2021| 6 Comments »

Black Saddlebags dragonflies (Tramea lacerata) are definitely migrating through my area. I have seen more than a dozen of them overhead during several visits this week to Occoquan Bay National Wildlife Refuge. It is really cool to see them hawking for insects in mixed groups that include Common Green Darners and Wandering Gliders, two other species that also migrate.

These three species spend most of their time in flight—they eat while they are flying—and it is rare for me to see one perched. Still, I track them and chase after them, hoping that these long-distance dragonflies will eventually come down to earth for a rest.

On Thursday, my patience was rewarded and I was able to get some shots of perched Black Saddlebags dragonflies. There were actually two individuals that perched briefly on separate branches of a fallen tree during a short period of time. I am not sure if the two shots below are of the same dragonfly or of different ones, but I really like the poses were wonderful in either case.

Have a wonderful weekend.

Dragonfly on a wire

Posted in Dragonflies, dragonfly, Nature, Photography, Summer, wildlife, tagged , , , , , , on September 3, 2021| 10 Comments »

Normally I do not like to have manmade objects in my wildlife photos, but in this image of a dragonfly perching on a twisted wire, I really like the juxtaposition of the natural and manmade elements.

The dragonfly is a very mature female Great Blue Skimmer dragonfly (Libellula vibrans)—the bodies of females of this dragonfly species get darker as they age and this one seems to have an almost bronze-like patina. Although there was plenty of vegetation around, she repeated perched on this wire that was blocking one of the trails on Monday at Occoquan Bay National Wildlife Refuge.

The diverse linear elements really draw my eyes to this image—the soft green lines of the vegetation in the background; the crisp angular lines of the leading edges of the wings; the slightly raised line formed by the dragonfly’s body; and the twisting lines of the wire.

No privacy

Posted in damselfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on September 2, 2021| 14 Comments »

It is hard to get privacy for some summer loving and rivals may try to interfere when you are a damselfly. That appeared to be the case on Monday at Occoquan Bay National Wildlife Refuge for this couple of Big Bluet damselflies (Enallagma durum) that I spotted in flagrante delicto.

Feeling a little bit like a voyeur, I was focusing on the couple when I was unexpectedly photobombed by a second male Big Bluet. As I noted yesterday, it is challenging to capture images of a flying dragonfly and it is even harder to get an in-flight shot of a damselfly. In this case it was a matter of luck and quick reactions, rather than skill, that allowed me to get the photo of the incoming damselfly.

The couple changed their position a bit, but were undeterred by the intruder.  I was happy to capture the sidewards-heart shape that is typical of mating damselflies and even more thrilled with the way that the colorful background turned out in a preview of fall colors.

Flying overhead

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on September 1, 2021| 19 Comments »

Black Saddlebags dragonflies (Tramea lacerata) like to fly high overhead, back and forth over trails and fields in pursuit of tiny insects that are often invisible to my eyes. They are pretty easy to identify because of the distinctive large dark patches on their wings that you can pick out even when they are flying. They are a challenge to photograph, though, because they rarely seem to perch.

When I spotted this patrolling Black Saddlebags on Monday at Occoquan Bay National Wildlife Refuge, I decided to try to capture some in-flight action shots of the dragonfly. When I am trying to photograph a dragonfly flying over a pond, I can sometimes pre-focus on an area, because the dragonfly stays at the same height above the water and flies in a somewhat predictable pattern. That technique does not work, however, with a dragonfly like the Black Saddlebags that changes altitude and direction quickly and without warning.

The first two photos give you a pretty good look at the wing pattern of the Black Saddlebags. If you look really closely at the first photo, you will note that the dragonfly has tucked in its legs under the thorax (the “chest” area), probably for aerodynamic reasons.

In the final photo, I noted that the dragonfly’s legs were extended. What was going on? As I was processing the shot, I noted some small white spots in front of and just above the dragonfly. At first I thought these might be dust spots on my sensor, but they were in different places on different shots, so I rejected that hypothesis. I think that those white spots, which you can see in the final image if you click on it and look very carefully, are small insects and the dragonfly was extending its legs to snag those insects.

The Black Saddlebags is one of several dragonfly species that migrates in the fall and this one may have been fattening up in preparation for the upcoming journey. Whatever the case, it was a fun challenge to try to photograph this dragonfly flying overhead.

Big Bluet in August

Posted in damselfly, Insects, Macro Photography, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 31, 2021| 10 Comments »

The number of dragonflies of certain species seems to be dropping as we approach autumn, but there seem to be plenty of Big Bluet damselflies (Enallagma durum) still around at Occoquan Bay National Wildlife Refuge. Their bright blue coloration and relatively large size—about 1.3 – 1.7 inches (34 to 44 mm) in length—makes the Big Bluets easy to spot in the vegetation along a trail that runs parallel to the waters of the bay.

One of the big challenges when photographing dragonflies and damselflies is getting the entire subject in focus—their bodies are long and narrow and are often pointing in a direction that makes it impossible to get sufficient depth of field. This male Big Bluet cooperated by perching in a way that allowed me to photograph him from the side. The damselfly is nicely in focus, while the leafy background is mostly out of focus and does not distract the viewer’s eyes from the primary subject.

Yes, the dragonflies and damselflies are still hanging on in my area. I think I will continue to see and photograph them for at least another month or two before I gradually begin to shift my focus towards birds, which will again become my main focus during the colder months of the year.

Butterflies and thistle

Posted in Butterflies, Flowers, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , , , on August 30, 2021| 21 Comments »

The thistles  in bloom must have been absolutely irresistible to butterflies on Saturday at Occoquan Bay National Wildlife Refuge. I was delighted to spot an Eastern Tiger Swallowtail butterfly (Papilio glaucus) and a Great Spangled Fritillary butterfly (Speyeria cybele) feeding almost side-by-side at a small patch of thistle plants.

I love the color combinations in these shots that contrast the warmer tones of the butterflies with the cooler colors of the flowers and the background. I also really like the texture of the thistles that appear to be hard and thorny, but are actually quite soft to the touch.

Needham’s Skimmer in August

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 29, 2021| 16 Comments »

I was happy to finally photograph a mature male Needham’s Skimmer dragonfly (Libellula needhami) on Wednesday at Occoquan Bay National Wildlife Refuge. Earlier this season all of the ones I shot were immature and did not have the reddish-orange/brown tones that remind me that autumn is on the way.

Here in the northern hemisphere, autumn will begin in just a few days for those using the meteorological calendar, though many of us won’t start the season until the autumnal equinox on 22 September, according to the astronomical calendar. On the other side of the globe, spring is about to begin and new life is bursting forth in places like New Zealand and Australia, where some of my most devoted readers live. For them, the September equinox is the vernal equinox, and not the autumnal equinox and I look forward to seeing their photos of daffodils, crocuses, and other spring flowers.

Camouflaged dragonfly

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 28, 2021| 8 Comments »

Common Whitetail dragonflies (Plathemis lydia) often perch flat on the ground, where they are relatively easy to spot. When this pretty little Common Whitetail female decided on Wednesday to perch on the side of a large tree, however, she almost disappeared from sight—the pattern of the light and shadows and the muted tones of the bark and the vegetation growing on the tree served to camouflage her presence almost perfectly.

I really like the limited palette of colors in this image and the relative simplicity of the composition. The rough texture of the bark helps to break up the background of the image and add some visual interest without being overly distracting.

Toothy dragonfly

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 27, 2021| 10 Comments »

Although dragonflies do not actually have teeth, I could not help thinking that this female Blue Dasher dragonfly (Pachydiplax longipennis) had a bit of an overbite problem when she smiled and posed for me on Wednesday at Occoquan Bay National Wildlife Refuge. I wonder if an orthodontist would recommend Invisalign treatment for her problem—I cannot imagine seeing a dragonfly with traditional metallic braces on its mouth.

Have a happy Friday and a wonderful weekend.Blue Dasher

Question Mark in August

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 26, 2021| 8 Comments »

I love it when I can get a shot that simultaneously shows the exterior markings and internal colors of a butterfly, especially when the butterfly’s outward appearance is somewhat drab. That was certainly the case with this Question Mark butterfly (Polygonia interrogationis) that I spotted last Saturday at Occoquan Bay National Wildlife Refuge. When it kept its wings closed, the butterfly blended right in with the dried vegetation in the background. As it opened its wings, the butterfly gave me a glimpse of the beautiful warm tones of its orange and brown interior.

In case you are curious about the name of this species, it comes from the white markings on the hind wing that some scientist decided resembled a question mark. The similar-looking Eastern Comma butterfly has a smaller “hook” and does not have the “dot” of the question mark. That dot is sometimes faded or missing, but fortunately there is also a way to tell the two species apart on the basis of the pattern of spots on the interior of the wings.

Female Calico Pennant

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 24, 2021| 22 Comments »

I was happy to see that some of my favorite dragonflies were still around when I visited Occoquan Bay National Wildlife Refuge last Saturday, including this beautiful female Calico Pennant dragonfly (Celithemis elisa). The bright colors—yellow for the female and red for mature males—and beautiful patterns on the wings of this species never fail to delight and amaze me.

This is the only location in our area where I can find Calico Pennants. As we move closer to the end of summer, I am never sure when I will see the last one of the season, so I look carefully for them each time I am at this refuge. You might think that it would be easy to spot Calico Pennants, because of their bright colors, but their small size—about 1.3 inches (33 mm) in length—makes them a real challenge to find and photograph.

You looking at me?

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 23, 2021| 8 Comments »

As I focused on this male Great Blue Skimmer dragonfly (Libellula vibrans), he wearily looked up at me. His wings were tattered and his body was scratched—it had already been a long summer for him.

I was fascinated by the shape and texture of the branch on which he was perched and positioned myself to capture those details. I made sure that the nearest eye was in focus, but did not worry that most of the body was blurry and that the angle made the wings almost disappear.

The resulting photo reminded my of the diagrams in my childhood geometry textbook depicting various angles—a cute dragonfly in an acute angle.

Simple Swallowtail Sunday

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on August 22, 2021| 19 Comments »

Some days I am guilty of overanalyzing my images, trying to figure out why I like or do not like them. Today, I decided to simply present this shot of a pretty Eastern Tiger Swallowtail butterfly (Papilio glaucus) that I spotted yesterday at Occoquan Bay National Wildlife Refuge as it fed on what looked to be some kind of sunflower.

I remember so well the words of the old Shaker song, “Simple Gifts” that I sang as part of a high school chorus:

‘Tis the gift to be simple, ’tis the gift to be free,
‘Tis the gift to come down where we ought to be;
And when we find ourselves in the place just right,
‘Twill be in the valley of love and delight.
When true simplicity is gained,
To bow and to bend we shan’t be ashamed;
to turn, turn, will be our delight.
Till by turning, turning we come round right.

Have a wonderful Sunday.

Looking down, looking up

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on August 6, 2021| 6 Comments »

How do I find all of the different dragonflies that I feature on my blogs? I like to visit a variety of habitats starting early in the spring and going later into the autumn. When I am out in the wild with my camera, I try to move relatively slowly as my eyes scan the ground, the vegetation, and the air for indications of dragonflies. Most of the time I need movement for me to detect a dragonfly and track a dragonfly, but sometimes I am able to spot a perched dragonfly.

During a recent visit to Occoquan Bay National Wildlife Refuge, I photographed two dragonflies that help to illustrate the importance of looking up as well as down when hunting for dragonflies. The male Widow Skimmer (Libellula luctuosa) in the first photo was perched low in some vegetation at the edge of a small pond. I watched the dragonfly fly to that perch, but my view was blocked by vegetation until I found a small visual tunnel that gave me a relatively clear view as I pointed my camera down at the dragonfly.

The male Great Blue Skimmer (Libellula vibrans) in the second photo, on the other hand, was perched high in the air in a field. Visually I had no trouble getting this shot as I pointed my camera toward the sky, but the ground was uneven and mucky and thorns were pricking my ankles as I composed the shot.

Down? Up? Straight ahead? My eyes are constantly moving when I am in target acquisition mode—that is one of the “secrets” of my dragonfly photography.

Portrait of a Big Bluet damselfly

Posted in damselfly, Insects, Macro Photography, Nature, Photography, Portraits, Summer, wildlife, tagged , , , , , , , , on August 5, 2021| 6 Comments »

I am fond of challenging myself by photographing difficult subjects like tiny spiders and dragonflies in flight. However, I find equal joy in capturing the beauty of more common subjects in simple portraits, like this image of a male Big Bluet damselfly (Enallagma durum) that I spotted on a recent trip to Occoquan Bay National Wildlife Refuge.

Beauty is everywhere.

Tattered Viceroy Butterfly

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on August 2, 2021| 6 Comments »

I am still waiting to see my first Monarch butterfly of the year, but was nonetheless excited to spot this similar-looking Viceroy butterfly (Limenitis archippus) recently at Occoquan Bay National Wildlife Refuge. The butterfly was looking a bit tattered, but its flight abilities seemed unaffected. Every year I am shocked anew at the ability of butterflies to function with significant wing damage.

The Monarchs and Viceroys have the same orange and black coloration, though the Viceroy is a bit smaller in size. The main visual difference between the two species is the black line across the Viceroy’s hind wings that is not present in Monarchs.

This is a modest little shot of this butterfly, but I really like the curve of the vegetation that is serving as a perch and the wonderful shadow that the butterfly is casting onto that vegetation.

Black Swallowtail in July

Posted in Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 28, 2021| 14 Comments »

How close should I try to get to my subject? How much attention should I pay to environmental elements when composing a shot? When is the decisive moment to grab a shot when the subject is in motion? These were some of the thoughts swirling through my head when I spotted this Black Swallowtail butterfly (Papilio polyxenes) last Friday at Occoquan Bay National Wildlife Refuge.

There are several dark swallowtails in our area, including the Spicebush Swallowtail, the Pipevine Swallowtail, the dark morph of the Eastern Tiger Swallowtail, and the Black Swallowtail. Sometimes it is hard to tell them apart, but in this case I spotted the black dots inside of the orange dots in the area between the wings, one of the identifying marks of a Black Swallowtail.

The first shot was one of the earliest shots that I took and I remember staying far enough away from the butterfly to be sure that I included the curl of the leaf coming out of the stalk of vegetation. I also tried to time my shot to catch the butterfly with its wings spread wide and was mostly successful.

I moved in closer and captured the second image, which shows more of the details of the butterfly. Although the camera settings remained the same, the background is more out of focus than in the first shot, because depth of field tends to get shallower when you get closer to a subject. I also tried to shoot from a slightly higher angle by standing on my tiptoes—you can see more of the vegetation over the butterflies left eye in the second image than in the first.

I chased this butterfly around as it flew about and waited patiently for it to perch again. I captured the final image when it landed on a different kind of plant. Normally a shot like this when the subject is facing away from you is not a good shot and is derisively referred to as a “butt shot” by many photographers. In this case, however, I was struck by the way that the angle of the butterfly’s wings complemented the angular shape of the plant’s leaves and I like the abstract feel of the image that I captured.

Colorful Calico Pennants

Posted in Dragonflies, dragonfly, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 27, 2021| 17 Comments »

I am always excited to see the brightly colored bodies and patterned wings of Calico Pennant dragonflies (Celithemis elisa). Calico Pennnants are small in size, with a length of only 1.1 to 1.3 inches (29-34 mm), and often perch in dense vegetation of fields adjacent to the water, so they are often difficult to spot. I can usually plan on getting scratched up a bit when photographing them and sometimes come away with chigger bites.

Last Friday I was particularly happy when I managed to get shots of both a male and a female Calico Pennant at Occoquan Bay National Wildlife Refuge. Males have a red and black pattern on their bodies, while females (and juvenile males) are yellow and black—the Calico Pennant in the first photo is a male and the one in the second is a female. Both genders have exquisitely detailed patterns on their wings that also help to distinguish them from other dragonflies.

Another Halloween Pennant

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 26, 2021| 12 Comments »

Halloween Pennant dragonflies (Celithemis eponina) are among the most photogenic dragonflies that I am blessed to photograph. The way that they perch at the extreme tips of vegetation makes it relatively easy to separate them from the background and highlight the beautiful patterns of their wings. Often I am able to move relatively close and shoot upwards with the sky as the background, as in the second image, though at other times I enjoy including the green shades of vegetation instead.

I spotted this striking dragonfly, which I believe is a female Halloween Pennant, last Friday as I was exploring a field at Occoquan Bay National Wildlife Refuge. Unlike many dragonflies that are found at the edge of a pond or a marsh, the Halloween Pennants that I see are usually perched in the tall vegetation at the edge of fields away from the water.

My final photo was my attempt to see eye-to-eye with the dragonfly. I really like the unusual perspective in the resulting photo and the way that the angle of view causes the wings, which usually play a dominant role in photos of dragonflies, to almost disappear from view.

Curlicue branch

Posted in Art, Dragonflies, dragonfly, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 25, 2021| 13 Comments »

The dragonfly was high in the tree and almost completely silhouetted when I spotted it on Friday at Occoquan Bay National Wildlife Refuge. Conditions did not seem optimal for capturing an image, but as I looked through the viewfinder of my camera, my eyes were attracted to the curlicue shape of the branch on which the dragonfly was perched. The branch, I realized, was actually the main subject of the image that I wanted to create.

I was far enough away that I could move about freely without fear of spooking the dragonfly, so I tried a number of different angles of view and shooting positions. As I later looked through the images on my computer, the placement of the sky and the clouds in the frame made me decide to feature this particular shot.

As for the dragonfly, I believe that it is a female Great Blue Skimmer (Libellula vibrans). Despite the shadowy silhouette created by shooting into the sun, there are just enough details for me for me to identify the dragonfly with a reasonable degree of certainty, though, as I noted earlier, my primary goal was to draw the viewer’s attention to the spiral shape of the curlicue branch.

Mating Big Bluet damselflies

Posted in damselfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , on July 17, 2021| 5 Comments »

I spotted this Big Bluet damselfly (Enallagma durum) couple in flagrante delicto on Monday at Occoquan Bay National Wildlife Refuge. Although I could not help but notice the sidewards heart that their bodies form when they are mating, it was the other elements of the scene that really caught my eye. The shapes and shadows of the leaf and its gnawed-away holes all add visual interest and make a perfect backdrop for this little vignette of an intimate moment in the lives of these damselflies.

Perching Prince Baskettail

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , , on July 16, 2021| 11 Comments »

I was shocked and thrilled to spot a Prince Baskettail dragonfly (Epitheca princeps) perched in a tree on Monday at Occoquan Bay National Wildlife Refuge. This was only the second time that I have seen one that was not flying—they never seem to take a break. As the Dragonflies of Northern Virginia website succinctly states, “Flies almost constantly, rarely perches.”

Earlier in the day I had seen Prince Baskettails several times, flying overhead as I walked along a trail parallel to the waters of Occoquan Bay. Those of you who have followed my blog for a while know that I can never resist the chance to attempt to capture a shot of a dragonfly in flight. This time was a bit different, though, because I was using my long telephoto zoom lens and the dragonfly was not flying over the water, but was high in the air. The second image was one of my more successful attempts.

Normally the only place where I see Prince Baskettails at this time of the year is at a small pond at Jackson Miles Abbott Wetland Refuge, where the Prince Baskettails fly repeated patrols low over the water. I have had some success in capturing shots of them in flight, like the final photo that I took last Thursday as a Prince Baskettail was flying by parallel to my position on the shore.

Halloween Pennant dragonfly in July

Posted in Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged , , , , , , , on July 15, 2021| 14 Comments »

I was happy to spot this Halloween Pennant dragonfly (Celithemis eponina) on Monday at Occoquan Bay National Wildlife Refuge as it perched high in the air on a tall stalk of Eastern Gamagrass. This is my first Halloween Pennant of the season and I have always loved seeing the beautifully patterned wings of this species. As you can see from this photo, Halloween Pennants like to perch on the uppermost tips of vegetation, which causes them to flap in even the slightest breeze, like a pennant.
I had made a trip to this wildlife refuge to check on the status of the bald eagles that I featured in yesterday’s posting and was walking around with my 150-600mm telephoto lens on my camera when I saw this dragonfly. Normally I am reluctant to to try to photograph dragonflies with this lens, because the shots are sometimes a little soft when the zoom lens is fully extended. However, the lighting was good and I am happy with the amount of detail that I was able to capture—click on the photo if you want to check out all of the cool details of this colorful dragonfly.

Young eagles in July

It has been several months since I last checked on the Bald Eagle (Haliaeetus leucocephalus) nest at Occoquan Bay National Wildlife Refuge, so I made a visit there on Monday to check on the eaglets. The young eagles that I found still hanging around the nest are definitely no longer babies, though most people would not yet recognize them as Bald Eagles—it takes almost five years for them to acquire their distinctive white heads and tails.

I am pretty sure that these two eaglets are now capable of flight, though they remained in place on the branches overlooking the nest the entire time that I observed them. For the first time in quite some time I had my 150-600mm lens on my camera that allowed me to zoom in on each of the eaglets and then zoom back for the final shot to give you an idea of how close they were to the nest.

The bedraggled plumage makes it look like it was really windy, but in fact there was no wind when I captured the images. The eaglets clearly have a lot of work to do on their grooming before they are ready to take their place as one of our national symbols.

I did not see any adult Bald Eagles until much later in the day when I spotted one in another part of the wildlife refuge. Although the eaglets appear to be more or less full grown in terms of size, I question the degree to which they are self-sufficient and suspect that they are still dependent on their parents to provide them with food. As their flying skills improve, the eagles will almost certainly venture out farther and farther and it will become correspondingly more difficult for me to spot them.

Goose family

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , on May 25, 2021| 8 Comments »

I have not seen many baby birds this spring, so it was exciting to spot this little Canada Goose family last week swimming together in the waters off of Occoquan Bay National Wildlife Refuge. Canada Geese (Branta canadensis) are so common where I live that many people consider them to be a nuisance, but I love to observe and photograph them.

Earlier this spring I noticed that a Canada Goose had established a nest on top of one of the wooden duck blinds and I wonder if these little goslings were hatched in that nest. Whatever the case, springtime is such a wonderful time to celebrate new life in all of its forms—and you have to admit that those three baby geese are really cute.

Green Heron in May

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , on May 25, 2021| 24 Comments »

Great Blue Herons remain in my area throughout the winter, but the much smaller Green Herons (Butorides virescens) depart in the autumn for warmer locations. It is always exciting for me when these colorful little herons return in the spring. Green Herons have always struck me as having more outgoing personalities than the more stoic Great Blue Heron and I love to watch them.

Normally I see them down at water level, often partially hidden by the vegetation, which makes them a challenge to photograph. Last week during a visit to Occoquan Bay National Wildlife Refuge, however, I spotted a Green Heron that had chosen a higher perch that allowed me to get an unobstructed shot. I really like the heron’s pose as it alertly surveyed the surrounding area.

Defying gravity

Posted in Birds, Nature, Photography, spring, wildlife, tagged , , , , , , , on May 21, 2021| 16 Comments »

When I saw an osprey couple trying to build a nest earlier this spring on a channel marker in the waters off of Occoquan Bay National Wildlife Refuge, the building site seemed way too small. Amazingly the ospreys (Pandion haliaetus) found a way to add an overhanging extension that seems to defy gravity. The couple seemed comfortable in the nest, which appear to be capable of easily holding their weight.

A neighboring osprey couple had the opposite problem—they had too much space. The ospreys used only half of the space for their nest and could easily have shared the other half with another couple, but I think that ospreys like to keep their neighbors at arm’s length, or maybe it would be better to say “at wing’s length.”
