I was delighted this past Tuesday to spot what I am pretty sure is a Blue-faced Meadowhawk dragonfly (Sympetrum ambiguum) during a visit to Occoquan Bay National Wildlife Refuge. The lighting was not that great when I took this shot, but the eyes of this dragonfly look to me like they are more blue than brown—if they were brown, then I would probably conclude that this was an Autumn Meadowhawk.

Whatever the case, it is still exciting for me to spot any dragonflies at all in the middle of October. For many people, Halloween is the time when they ask the question,”Trick or Treat?”—I got my “treat” a bit earlier this year.

Yesterday (13 October) I spotted my first Autumn Meadowhawk dragonflies (Sympetrum vicinum) of the season during a visit to Occoquan Bay National WIldlife Refuge. This dragonfly species is generally the last one to disappear and in some past years I have spotted Autumn Meadowhawks as late as December.

Autumn Meadowhawks are relatively small dragonflies—a bit over an inch in length (26-35 mm)—and have bright red bodies, as you can see in this image that I captured yesterday. They are somewhat similar in appearance to to Blue-faced Meadowhawks, another autumn species that also have red bodies, but their eyes and “faces” are different colors—Blue-faced Meadowhawks have blue eyes and, as their name suggests, bluish faces, while Autumn Meadowhawks have brown eyes and tannish faces.

Earlier this month I went out with my camera to Occoquan Bay National Wildlife Refuge, looking for dragonflies that appear in the autumn, such as the Autumn Meadowhawk and the Blue-faced Meadowhawk. Alas, I did not spot any of these dragonflies with bright red bodies, but I was delighted to see that this striking female Eastern Pondhawk dragonfly (Erythemis simplicicollis) was still around.

Eastern Pondhawks are quite common in my area during the summer months, but are often difficult to see, because their emerald green bodies (for the females and immature males) tend to blend in with the abundant vegetation. That vegetation is starting to die off and dry out now, so I had no trouble tracking this dragonfly in the air and seeing when it landed. Achieving sharp focus was a bit more of a challenge, because my camera tended to focus on all of the various reeds and sticks in the background—I ended up shifting to manual focus to capture this image.

We are in a bit of a cloudy and rainy period right now, but I plan to go out again in the next week of so to search for the remaining dragonflies, many of which will be gone by the end of October.

Last week at Occoquan Bay National Wildlife Refuge I managed to photograph this beautiful little Gray Hairstreak butterfly (Strymon melinus) as it was feeding on a flowering goldenrod plant. If you double click on the image you can see the extended proboscis, a hollow tube that the butterfly uses to suck in the nectar from the flowers. I was delighted also that I was able to capture tiny details, like the little tails of the hind wings and the colorful markings.

Many of the larger butterflies seem to be disappearing as we move deeper into autumn, but quite a few of these smaller butterflies are still active in my area.

How do you spot subjects for your wildlife photographs? My eyes are generally attuned to movement and if a subject remains still, there is a pretty good chance I will not spot it as I scan my surroundings. I was thrilled, therefore, last Friday when I spotted this little Green Tree Frog (Drophytes cinereus) in the vegetation at the edge of a trail at Occoquan Bay National Wildlife Refuge. You can get a sense of how small and light the frog was if you look closely at the bent stem on which it is napping.

Somehow my eyes managed to pick out its shape as I was looking for dragonflies an other insects. I maneuvered around a bit to get this shot, but fortunately I did not disturb the little frog. As I understand it, this species is mostly nocturnal, so the frog really might have been sleeping. Tree frogs almost always look like they have sleepy eyes, so I can never tell for sure when they are actually sleeping—as far as I can tell, they do not snore.

I was pleased to see a few pops of autumn color starting to emerge during a visit on Wednesday to Occoquan Bay National Wildlife Refuge. I grew up in New England and have memories of spectacular displays of colorful foliage. Unfortunately the fall colors in Northern Virginia are significantly more muted by contrast. Still, I really enjoy the changing season, when the nights are cool and the days are still warm.

Today is supposed to be another beautiful autumn day and I plan to spend a good part of it outdoors with my camera, hoping to capture a few photos of the remaining dragonflies.

I was delighted yesterday (30 September) to spot this pair of Common Buckeye butterflies (Junonia coenia) feeding on some goldenrod (I think) plants at Occoquan Bay National Wildlife Refuge. I did not spot many dragonflies during my visit, but was delighted to see some many butterflies that were active in the abundant sunlight, including a Monarch butterfly (Danaus plexippus) that is probably passing through our area on a journey southward to a warmer location. I am including the shot of the Monarch in this posting because I love Monarch butterflies, though I note in passing that the shot is slightly out of focus.

Happy October!

I haven’t gone out in the wild quite as much this month as normally, but earlier in June I captured this cool shot of a Needham’s Skimmer dragonfly (Libellula needhami) during a visit to Occoquan Bay National Wildlife Refuge. I absolutely love the gold veining near the leading edges of the wings of this species that really make them sparkle.

The weather has turned nice, but reports of swarming flies at my favorite wildlife refuge have deterred from making more frequent visits. I may have to spend some time at some other local spots to search for photo opportunities of dragonflies and other potential subjects.

I captured this shot of a beautiful Great Spangled Fritillary butterfly (Speyeria cybele) feeding on a milkweed plant during a recent visit to Occoquan Bay National Wildlife Refuge. This is a pretty simple composition, but I really like its blend of color and textures.

What can I say? I like what I like.

I spotted lots of Zebra Swallowtail butterflies (Eurytides marcellus) on Tuesday (9 June) during a visit to Occoquan Bay National Wildlife Refuge. It was pretty difficult, though, to get a shot of one, because they were constantly in motion. I chased after a number of them and finally one landed for a moment. Trying to control my breathing, I waited for the butterfly to open its wings fully and finally I managed to capture this image.

I couldn’t help but notice that one of the “tails” was considerably shorter than the other one. At first I wondered if the shorter tail was the result of a predator trying to grab the butterfly by the “tail.” When I looked closely, though, the cut seemed to be so clean, so I considered the possibility that the butterfly emerged from its chrysalis with this deformity. Whatever the case, the unequal sized tails did not seem to affect the butterfly’s ability to fly.

Milkweed plants were flowering at Occoquan Bay National Wildlife Refuge on Tuesday (9 June) and the pollen baskets (corbiculae) on the hind legs of this bee were filled to overflowing. The bright orange concentration of pollen made it easy to track the bee, though its constant motion made it really tough to get a decent photograph.

Most often I think of pollen as being yellow in color, but in the past I have taken photos of bees covered in pollen that was another color. The third photo below from a post in May 2020 shows red pollen from Purple Deadnettle flowers (Lamium purpureum). The final photo below showing a bee covered in white pollen from a chicory flower is from one of my posts in August 2014.

I have a pretty memory of the subjects that I have photographed, but often can’t remember when I took the photos. When I did a Google search of “Mike Powell multi-colored pollen,” the results began with an AI summary that surprised me. It indicated that “Nature photographer Mike Powell frequently highlights the fascinating, vibrant spectrum of pollen colors collected by pollinators. Through his macro photography in Northern Virginia’s parks, he captures how pollen isn’t just yellow, but can appear in brilliant shades of blue, orange, red, pink, and white.”

Google also included a link to my blog, which my help to explain why my views have been unusually high this year, despite the fact that I have been posting less frequently than in the past. I am not a big fan of AI and am particularly negative about generative AI, but I have to admit that AI did a pretty good job in summarizing a large body of information, in this case my blog postings from 2012 to the present. Wow! It’s hard to believe that I have kept the blog going for that long.

I was delighted to spot this female Unicorn Clubtail dragonfly (Arigomphus villosipes) yesterday (9 June) during a visit to Occoquan Bay National Wildlife Refuge, my favorite nearby location for wildlife photography. Most of the Unicorn Clubtails that I have photographed in the past have been males, primarily at the edge of ponds, but this female was in a vegetated area away from the water.

How do I know this is a female? One of the most reliable ways is to look at the shape of the tips of the dragonfly’s abdomen (its “tail”). I have attached a photo of a male Unicorn Clubtail from a recent blog posting  (second photo below) to visually illustrate some of the differences between a female and a male Unicorn Clubtail.

On rare occasions, though, I have spotted female Unicorn Clubtails flying over the water. Unlike some other clubtail dragonfly species that deposit their eggs into plant tissue, female Unicorn Clubtails oviposit by hovering and repeatedly tapping the tips of their abdomens directly on the surface of the water. I have been fortunate to observe this in the past and captured a shot from June 2019 (third photo below) that shows a flying female Unicorn Clubtail dragonfly with the ripples in the water from depositing eggs (click here for more details about that encounter).

I love trying to get photographs of Zebra Swallowtail butterflies (Eurytides marcellus). There is an understated elegance to their monochromatic coloration (with pops of blue and red) and they are so hyperactive that I have to chase after them to have a chance to get a shot when they perch momentarily. Earlier this month I captured this image of one that highlights its long tails and colorful antennae.

There is something almost magical about chasing butterflies that makes me feel like a child again. I hope I never lose that energy, enthusiasm, and boundless curiosity.

Each spring (and fall) migrating warblers move through our area. This period is particularly frustrating for me, because I can often hear the warblers singing and calling, but I only rarely catch a glimpse of one.

Last week, though, I heard a warbler and was able to track it as it moved feverishly in and out of the foliage at Occoquan Bay National Wildlife Refuge. I was definitely helped by the bright yellow plumage of the bird, that turned out to be a Prothonotary Warbler (Protonotaria citrea). Prothonotary Warblers are almost completely covered in yellow feathers and therefore can’t completely hide themselves. In case you are curious, the bird’s names comes from its plumage that resembles the yellow robes once worn by papal clerks in the Roman Catholic Church, known as prothonotaries.

As I was walking down a trail last Friday at Occoquan Bay National Wildlife Refuge, I noticed a large black snake preparing to cross the trail. I know that there are very few poisonous snakes in my area, so I was not worried about being bitten. Instead I stopped walking and focused my camera on an open area that the snake would be moving through.

The snake was moving quite slowly and was flicking its tongue a lot, which I thought was a little strange. Later, when I was reviewing the images on my computer, I noticed that the eyes of the snake were cloudy and bluish, a definite sign that the snake was getting ready to shed its skin, a process that generally takes about a week. Perhaps the snake’s vision was impaired and it was using its tongue to assist in navigation.

I believe that this is a Central  Ratsnake (Pantherophis alleghaniensis), a large snake that is quite common in Virginia. After I captured a few images and the snake finished crossing the trail and I continued along it, with my eyes and ears on alert to find my next subject to photograph.

The trees are definitely starting to blossom, providing a nice backdrop for this White-throated Sparrow (Zonotrichia albicollis) that I photographed a little over a week ago at Occoquan Bay National Wildlife Refuge. These sparrows overwinter in our area and will be departing soon for more northern regions for breeding.

The ospreys (Pandion haliaetus) are definitely back at Occoquan Bay National Wildlife Refuge after spending the winter in warmer locations. I captured these images last week of an osprey as it was enjoying a freshly caught fish. I tried to vary the angles a bit for the individual shots, but moved slowly and carefully so that I did not disturb the osprey during its breakfast.

Butterflies are already starting appear at Occoquan Bay National Wildlife Refuge, including this tiny Spring Azure butterfly (Celestrina ladon) that I photographed there on 20 March. These little butterflies look pretty nondescript when their wings are close, but when they are flying, you can see the beautiful blue coloration of their inner wings.

Spring Azure butterflies are almost always the first butterflies that I see in the spring. A few other species, like Mourning Cloaks, overwinter as adults, but Spring Azure butterflies spend the winter in the pupal stage in a chrysalis and emerge as adults in the early spring.

I got involved in a little staring contest with a Bald Eagle (Haliaeetus leucocephalus) last Friday at Occoquan Bay National Wildlife Refuge. I moved slowly and deliberately to get some photos and then departed silently, leaving the eagle in peace on its perch.

Most of the time my first indication that there is an eagle in the area is when it takes off in response to my presence. In this case, however, the eagle looked right at me and seemed to decide that I did not represent a threat, so it stayed in place.

I like that kind of peaceful coexistence.

When it’s this early in the spring, I try to photograph as many of the birds that I encounter as I can. Blue Jays (Cyanocitta cristata) are pretty common where I live, but I rarely have the chance to photograph one. Earlier this month I was thrilled to hear and see this Blue Jay during a visit to Occoquan Bay National Wildlife Refuge.

The Blue Jay was busily foraging in the trees, rarely stopping in any one place for very long. I was thrilled to capture this shot of the jay when it paused momentarily with some kind of berry that it had just snagged. It is not a great photo, but I like the overall feel of the photo, with the blues and greens working well together to create a pleasant image.

I couldn’t help but notice the sight and sounds of little birds last week at Occoquan Bay National Wildlife Refuge—they were really active. Of course, being aware of their presence did not magically result in photographs of them. As many of you know, one of the “secrets” of my wildlife photography is that I am unusually patient and persistent.

So I watched and waited and eventually managed to capture images of Carolina Chickadees (Poecile carolinensis), some of the smallest birds in our area. Here are a few of my favorites. In the first one, I managed to isolate the little bird from its cluttered background, which was a bit tricky, considering that the chickadee was perched on a small branch in the midst of a tangled group of branches.

The second photo was a little easier to take, because the bird was perched at the end of a branch in a more open area. The final photo was an unplanned one. As I was focusing on the chickadee, it took off and I instinctively pressed the shutter release. The photo is far from perfect, but I really like it.

I’m sure I’ll be taking more (and hopefully better) bird photos as we move deeper into spring and I’m looking forward to seeing a few dragonflies appearing in the next month or so.

I could easily hear this Brown Thrasher (Toxostoma rufum) singing high in the trees this past Tuesday at Occoquan Bay National Wildlife Refuge, but I had a hard time getting an obstructed view of it because it was hidden in the branches. I waited and waited and eventually the Thrasher moved to a more open spot. I was delighted when I managed to capture a shot when it started singing again.

According to some naturalists cited on the Cornell Lab of Ornithology website, “It is the opinion of many ornithologists that the song (of the Brown Thrasher)… is richer, fuller, and definitely more melodious than that of polyglottis” (the Northern Mockingbird).” I was also happy that I was able to get some good shots of the striking yellow eyes of the Brown Thrasher. Wow!

At this time of the year, the skies are often filled with migratory birds. I live in Northern Virginia, which seems to be a kind of midpoint in the journeys of birds that spend their winters in warmer places and then fly northward for breeding.

The most common birds that I see are Canada Geese, but this past Tuesday I was delighted to spot a couple of less common Species. In the first photo are some members of a large flock of American White Pelicans (Pelecanus erythrorhynchos). Although the photo makes it look like the birds were flying in a military-like formation, the grouping was often quite disorganized and was slow-moving. I couldn’t help but notice the “horn” on the upper bill of several of the pelicans that they will eventually shed after the birds mate and lay their eggs.

A short while later, I spotted a small group of Tundra Swans (Pelecanus erythrorhynchos), as shown in the second photo below. I noted that these swans fly with their necks fully extended, unlike the herons and egrets that I am more used to seeing that fly with their necks tucked in, creating an S-shape.

Tuesday was a warm, beautiful spring day and I managed to spot some additional birds in the trees and in the underbrush that I will feature in blog postings in the next few days.

Buffleheads (Bucephala albeola) are small sea ducks that I sometimes observe during the winter in the waters off of Occoquan Bay National Wildlife Refuge. The males have a large white patch on their heads that makes them relatively easy to identify. From a distance these males often look to be black and white. When the sun is shining from the right directions, as it was last week when I captured this image, you can see that their heads are actually a glossy green and purple that really helps to set off their distinctive white patches.

In addition to being able to see the colors, the straight-on angle of this shot shows the odd shape of the head of this bufflehead’s head. It may be a bit of an optical illusion, but it looks to me like the lower portion of its head is considerably bigger than the upper part.

Yesterday, 1 March, marked the start of meteorological spring for those of us who live in the Northern Hemisphere. Meteorologists divide the seasons into three month increments for easier data tracking, although in the United States we generally use the astronomical calendar that ties the start of spring to the vernal equinox, which is on March 20 in 2026. No matter how you calculate the start of spring, there are definite signs that the seasons are changing.

After a brutally cold period of weather in most of February, we had an unusually warm day on Saturday, the last day of the month. The sun was shining brightly throughout the day and temperatures soared to over 60 degrees (15.5 degrees C). I generally don’t go out with my camera on the weekends to avoid the inevitable crowds, but I couldn’t resist the pull of the beautiful weather and headed off to Occoquan Bay National Wildlife Refuge.

There were quite a few people at the refuge and most of the wildlife that I encountered was out of camera range, but that didn’t really matter. Like the turtles that had risen up from the bottom of the ponds, I enjoyed simply basking in the warmth of the sun.

I did manage to capture a shot of a distant Bald Eagle (Haliaeetus leucocephalus). Many of you know that I rarely pass up an opportunity to photograph an eagle, even when they are far away. As you can see from the blurry branches in the foreground, I had to bend and twist my body to get a clear view of the eagle through the thicket of branches that mostly blocked my view.

It will soon be nesting season for the eagles, so I’ll be checking out several locations at the wildlife refuge this month for signs of eagle activity.

When birds are perched in the trees during the winter, you often do not have a sense of their environment when you look at photos of them. Some sparrow species, however, like to poke about on the ground and when I manage to capture some shots of them, you get much better sense of the harshness of their environment, as was the case with this White-throated Sparrow (Zonotrichia albicollis) last week at Occoquan Bay National Wildlife Refuge.

White-throated Sparrow overwinter with us, but disappear during the warmer months when they fly north to breed. One of my favorite identification features for this species is the bright yellow stripe in their lores (the area between their eyes and their bills). This particular sparrow was feverishly poking about in the snow as if foraged for food and I was particularly pleased when it hopped up onto a log and gave me a chance to capture an unobstructed shot of it.

This Song Sparrow (Melospiza melodia) was facing away from me when I first spotted it last week at Occoquan Bay National Wildlife Refuge, but I waited patiently for it to move its head and was rewarded with this profile pose. Of course, my challenge was to capture the moment, and I was happy that I was able to get an unobstructed shot of the little bird.

You have to be out there to have opportunities like this and a combination of skill and luck (and quick reactions) to get the shot. As I learned long ago when I was a Boy Scout, it is important to “Be Prepared.”

I was thrilled to spot this Great Blue Heron (Ardea herodias) last week at Occoquan Bay National Wildlife Refuge. Unlike Great Egrets (Ardea alba) that migrate out of our area in the fall, Great Blue Herons remain with us throughout the entire year. A lot of the water at the wildlife refuge was frozen, but this heron managed to find an open stretch of water and was fishing at the side of what might be a beaver den.

When I am lucky enough to spot warblers, it is usually in the spring and autumn, when they are migrating through Northern Virginia where I live. One exception is the Yellow-rumped Warbler (Setophaga coronata) that stays here for much of the winter.

I was delighted to get a glimpse of this Yellow-rumped Warbler on Wednesday at Occoquan Bay National Wildlife Refuge and even more thrilled that I was able to capture a couple of shots of the handsome little bird. The warbler was feverishly foraging and was rather hyperactive. The challenge for me and my camera was to acquire the subject in my viewfinder as soon as I saw it and then to accurately focus on it before it flew to a new perch.

On this day, I more or less met the challenge with this warbler, but like all other wildlife photographers, I have plenty of stories of “the one that got away.”

An American Coot (Fulica americana) turned its head as it swam away from me yesterday at Occoquan Bay National Wildlife Refuge, allowing the light to illuminate its stunning red eyes that often remain hidden in the shadows.

This was the first time that I have been out with my camera in several weeks. I have been mostly housebound during that time, due to the frigid temperatures and lingering snow that has made driving a challenge. Here in Northern Virginia we are not used to dealing with this much snow and the only now are we starting to warm enough for the snow to start to melt.

Yesterday was warm enough that the icy top layer of the snow had softened enough that it was no longer slippery, but it also mean that I was sinking into the snow several inches as I trudged along the still snow-covered trails at the wildlife refuge.

I was happy to have a few encounters with birds and I’ll share some more photos in the next few days, but thought I’d get back to more regular postings, now that I have something to share.

When I spotted this Great Blue Heron (Ardea herodias) last week, it was perched uprignt in a tree at Occoquan Bay National Wildlife Refuge. Suddenly it seemed to develop an itch that absolutely had to be scratched.  The heron carefully balanced itself on one leg, bent its head down, and scratched away with its long nails.

Sometimes life is like that and you just have to scratch that itch immediately. Trust me, I’ve been there.
