Last Needham’s Skimmer?

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged Canon 7D, Libellula needhami, Needham's Skimmer, Needham's Skimmer dragonfly, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm on September 27, 2023| 2 Comments »

The weather this past week has been cool, cloudy, and rainy, with high temperatures struggling to reach 65 degrees (18 degrees C). I fear that many dragonflies will not survive and so I celebrate each sighting of a dragonfly species, conscious that it could be the last one that I see this season.

Last Thursday I spotted this Needham’s Skimmer dragonfly (Libellula needhami) while I was visiting Occoquan Bay National Wildlife Refuge. Its wings are tattered and its colors have faded, but it was still active.

Autumn often makes me pensive and I become more aware of the passage of time. Our lives are just as fragile and limited as those of the beautiful little insects that I am so fond of photographing. May we all find beauty, meaning, and love as we live our lives.

Red-footed Cannibalfly in September

Posted in Autumn, Insects, Nature, Photography, wildlife, tagged cannibalfly, Canon 7D, Occoquan Bay National Wildlife Refuge, Promachus rufipes, Red-footed Cannibalfly, Tamron 18-400mm, Woodbridge VA on September 26, 2023| 9 Comments »

Can you identify this insect? At first glance it looks a little bit like a dragonfly, but if you look more closely you may notice that the wings and eyes are different from those of a dragonfly and this insect’s body is a lot hairier. This is a robber fly and I am pretty sure that it is a variety known as a Red-footed Cannibalfly (Promachus rufipes). Yikes!

Red-footed Cannibalflies are one of the coolest and creepiest insects that you can encounter in the wild. As their macabre moniker suggests, Red-footed cannibalflies usually feed on other insects, but they reportedly are capable of taking down a hummingbird. Thankfully I have never seen that happen, since I really like hummingbirds, but several years ago I did photograph a Red-footed Cannibalfly with a large Hummingbird Moth that it had captured (see my 2017 posting Demise of a hummingbird moth).

A posting that I did in 2013 entitled “Red-footed Cannibalfly” amazingly has been one of my most popular postings ever, with almost 3300 views to date. Apparently more people search for information about Red-footed Cannibalflies that I would have anticipated.

I captured this image last Thursday as I was exploring some of the trails at Occoquan Bay National Wildlife Refuge in Northern Virginia.

Perching Black Saddlebags dragonfly

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged Black Saddlebags, Black Saddlebags dragonfly, Canon 7D, dragonfly in flight, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm, Tramea lacerata, Woodbridge VA on September 25, 2023| Leave a Comment »

I was happy last Thursday when a Black Saddlebags dragonfly (Tramea lacerata) that I had been tracking overhead at Occoquan Bay National Wildlife Refuge perched for a moment, allowing me to capture this first image. While it was flying, I attempted multiple times to get a shot of it, with minimal success. The second photo is my best one.

Some dragonflies spend a lot of their time perched, but Black Saddlebags are one of the species that spends most of its time in the air, so it is rewarding to be able to see one land and to get a shot of it. Black Saddlebags are also one of the few dragonfly species that are migrate although, according to the Dragonflies of Northern Virginia website, scientists do not fully understand why they do so and have been studying their migratory patterns.

Lesser Yellowlegs

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged Canon 7D, Lesser Yellowlegs, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm, Tringa flavipes, Woodbridge VA, yellowlegs on September 24, 2023| 1 Comment »

I almost always have trouble identifying shore birds, especially the different kinds of sandpipers. On Thursday, I spotted a single sandpiper-like bird in the shallow water of a pond at Occoquan Bay National Wildlife Refuge. Initially I thought it might be a Solitary Sandpiper, but when I got a good look at its legs, I leaned towards calling it a Lesser Yellowlegs (Tringa flavipes)—Solitary Sandpipers have greenish legs.

It was fascinating to watch the little bird move through the water, carefully raising its feet. On land, it seemed to prance a bit. In the final photo, the bird was flexing its wings as part of its grooming routine and seemed to be keeping an eye on me.

Brown Thrasher

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged brown thrasher, Canon 7D, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm, thrasher, Toxostoma rufum, Woodbridge VA on September 23, 2023| 4 Comments »

When I stepped out of my car on Thursday at Occoquan Bay National Wildlife Refuge, I notice a bird pecking about in the grass at the edge of the parking lot.The lenght of its tail made me think of a Northern Mockingbird, but the coloration was more sparrow-like. As I tracked the bird in my camera’s viewfinder, the bird lifted its head and I caught a glimpse of its bright yellow eye and realized that it was a Brown Thrasher (Toxostoma rufum), a species that I have seen only a few times before.

I really like the basic description of the species on the Cornell Lab of Ornithology website—”It can be tricky to glimpse a Brown Thrasher in a tangled mass of shrubbery, and once you do you may wonder how such a boldly patterned, gangly bird could stay so hidden. Brown Thrashers wear a somewhat severe expression thanks to their heavy, slightly downcurved bill and staring yellow eyes, and they are the only thrasher species east of Texas. Brown Thrashers are exuberant singers, with one of the largest repertoires of any North American songbird.”

Blue Grosbeak

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged Blue Grosbeak, Canon 7D, Occoquan Bay National Wildlife Refuge, Passerina caerulea, Tamron 18-400mm, Woodbridge VA on September 22, 2023| 8 Comments »

I was not able to get close to this Blue Grosbeak (Passerina caerulea) on Monday at Occoquan Bay National Wildlife Refuge, but was thrilled to get a shot that was good enough for me to identify the bird. As far as I know, this is the first time that I have photographed a Blue Grosbeak.

When I first spotted this bird, I thought that it was probably an Indigo Bunting. When I got home and looked more closely at the images, however, I noticed the reddish wing bars that are not found on an Indigo Bunting, so I scoured my bird identification book until I came across the Blue Grosbeak.

These two shots illustrate well the dilemma I have in photographing small birds at this time of the year. Many of them like to perch high in the trees and the leaves often hide them from view. When I hear a bird singing, I try to locate it, but am usually unsuccessful in doing so unless the bird moves. In a month or so, many of the leaves will be gone, but so will many of the birds that are now passing through our area.

Wild turkeys in the brush

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged Canon 7D, Meleagris gallopavo, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm, turkey, Wild Turkey, Woodbridge VA on September 21, 2023| 1 Comment »

On Monday I spotted these two Wild Turkeys (Meleagris gallopavo) at Occoquan Bay National Wildlife Refuge as they climbed a small hill through some tall grass. They kept disappearing from view, but occasionally their heads would pop up and I was able to capture a few shots of them.

The bodies of the turkeys are partially hidden by the vegetation, but I really like the way that I was able to capture a sense of the habitat in which I saw the turkeys. Normally I spot turkeys in the open on the trails at this wildlife refuge, so it was cool to see them traveling “off-road.”

On Monday I was thrilled to spot multiple Monarch butterflies (Danaus plexippus) during a visit to Occoquan Bay National Wildlife Refuge. The first shot is the typical kind of shot that I usually try to take, but I really like the third image that I captured of a distant Monarch butterfly in a field of flowers—so many flowers, so little time.

Russet-tipped Clubttail in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, wildlife, tagged Canon 7D, Fort Belvoir VA, Jackson Miles Abbott Wetland Refuge, Russet-tipped Clubtail, Russet-tipped Clubtail dragonfly, Stylurus plagiatus, Tamron 18-400mm, YouTube on September 19, 2023| Leave a Comment »

For the last few weeks I have been searching diligently for the late-season dragonfly species that appear on the scene in late August and early September. So far I have come up mostly empty-handed, but I was thrilled to spot this cool-looking Russet-tipped Clubtail dragonfly (Stylurus plagiatus) on 6 September at Jackson Miles Abbott Wetland Refuge. In my area, Russet-tipped Clubtails are seen most often in August and September, but they are somewhat uncommon.

As some of you know, I dabble a bit with YouTube. At about this time last year I did a little video about Russet-tipped Clubtails that you might enjoy watching. It was one of my first videos and lasts about a minute and a half. Click on this link to view the video in YouTube. I am also embedding a YouTube link at the end of this posting. Depending on how you are reading this blog, you may be able to watch the video from within the blog.

A year ago, I had aspirations of shooting more video footage during my photography outings. I have made only minor progress in that area, but it is still something that interests me a lot. I have learned the basics of making and editing videos, but am struggling to figure out what stories I want to tell and how a video can help me tell those stories.

Damsels in distress

Posted in Arachnids, Autumn, damselfly, Insects, Nature, Photography, spiders, wildlife, tagged Argiope aurantia, Big Bluet, Big Bluet damselfly, Black and Yellow Garden Orbweaver spider, Canon 7D, Enallagma durum, Occoquan Bay National Wildlife Refuge, Tamron 18-400mm, Woodbridge VA on September 18, 2023| 3 Comments »

As we move deeper into September I have been seeing more and more Black and Yellow Garden Orbweaver spiders (Argiope aurantia). These spiders are impressively large and have prominent webs with a distinctive zigzag pattern near the center.

During recent visits to Occoquan Bay National Wildlife Refuge, I have seen multiple Big Bluet damselflies (Enallagma durum) that have gotten caught up in the webs of the Argiope spiders. In the first photo the spider is moving in on two damselflies. After immobilizing the prey, the spider will often wrap it in web material, as you can see in the second image.

The final shot shows a hapless damselfly entangled at the edge of a web. I observed the damselfly for a few moments to see if I could detect any signs of movement, with thoughts that I might be able to free it. However, I did not see any movement and suspect that I had arrived too late to rescue this damsel in distress.

Some viewers may object to these kind of graphic images, but for me it is part of the “circle of life” in nature—all creatures have to eat to survive. As I have observed numerous times, today’s predator may well become tomorrow’s prey.

Dragonflies in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged Calico Pennant, Canon 7D, Celithemis elisa, Eastern Amberwing, Eastern Pondhawk, Erythemis simplicicollis, Fort Belvoir VA, Great Blue Skimmer, Jackson Miles Abbott Wetland Refuge, Libellula needhami, Libellula vibrans, Needham's Skimmer, Occoquan Bay National Wildlife Refuge, Perithemis tenera, Tamron 18-400mm, Woodbridge VA on September 17, 2023| 10 Comments »

In many of my blog postings, I concentrate on a single species of dragonflies, but today I want to celebrate the diversity of species that I have been seeing during the month of September. Despite my warnings in some earlier postings about the decreasing numbers of dragonflies, I continue to see a variety of species—Northern Virginia, where I live, is blessed to have an abundance of different dragonflies and damselflies.

The first photo shows a female Eastern Amberwing (Perithemis tenera), the smallest dragonfly in our area. Males of this species hang out at ponds, but the females, which do not have amber wings like the males, are usually found in vegetation some distance from the water.

The second image shows a male Calico Pennant (Celithemis elisa), a beautifully colored dragonfly with distinctive patterns on its wings. The third image shows a mature female Needham’s Skimmer (Libellula needhami). Her wings show some damage and her color has fades, but she is still beautiful and the golden strands on the front edges of her wings were sparkling in the sunlight when I captured this image.

The fourth image shows a female Eastern Pondhawk (Erythemis simplicicollis), one of the most common dragonfly species in my area. I love the brilliant emerald color of the females (and immature males) of this species and the black markings on the abdomen.

The dragonfly in the last photo was the toughest one for me to identify. It had flown up into a tree and I was looking into the sun when I captured the image. However, I am pretty sure that it is a female Great Blue Skimmer (Libellula vibrans).

All of these dragonflies belong to the Skimmer family, the largest dragonfly family that includes the species most likely to be seen by a casual dragonfly watcher. The other families, which are generally harder to find, include Clubtails, Cruisers, Darners, Emeralds, Petaltails, and Spiketails. If I remember correctly, I have managed this season to photograph at least one dragonfly in all seven of these dragonfly families.

Dragonflies in the air

Dragonflies were flying overhead at several locations at Occoquan Bay National Wildlife Refuge on Thursday, including a Common Green Darner (Anax junius), multiple Black Saddlebags (Tramea lacerata), and at least one Wandering Glider (Pantala flavescens). The Wandering Glider, alas, was elusive and I could not get an in-flight shot of it, but I did manage to get a shot of a Common Green Darner (1st photo) and a Black Saddlebags (2nd photo).

All three of these dragonfly species are migratory species. Migrating dragonflies will often fly in mixed swarms that are large enough that they are sometimes picked up by weather radars. For more details about this phenomenon, check out this September 2019 article in the Washington Post entitled “Weather radar is picking up swarms of dragonflies from the Midwest to the Mid-Atlantic.”

Heron at water’s edge

On Thursday at Occoquan Bay National Wildlife Refuge I captured this image of a Great Blue Heron (Ardea herodias) at water’s edge. Heron’s are quite large and normally are easy to spot.

However, as I was approaching this area, this Great Blue Heron was initially hidden from view by the metal posts sticking out of the water, as you can see in the second photo. Fortunately the heron’s head was turned to the side and it was the bird’s large bill that gave away its presence. I had to walk farther down the trail and look back to get the viewing angle for the first photo in which the heron is somewhat separated from the posts and is more visible.

Autumn Vibes

For those of us in the northern hemisphere who use the astronomical calendar, tomorrow (23 September) marks the beginning of the autumn season. In so many of the photos that I have taken during the past few weeks, I have noted signs of the changing seasons.

The warm orange tones in this shot of a female Needham’s Skimmer dragonfly (Libellula needhami) remind me of pumpkins and autumn leaves. The fading flowers in the photo of a male Common Whitetail dragonfly (Plathemis lydia) remind us that the growing season is coming to an end. The dryness of the stalk on which the Slaty Skimmer (Libellula incesta) dragonfly perch brings to mind the droughts and extreme weather that many have experience during this summer.

Embrace the new season and the opportunities is provides, whether it be autumn in the northern hemisphere or spring for those in the southern hemisphere.

White-banded Crab Spider

On Monday I captured this shot of a small white spider—I think it may be a White-banded Crab Spider (Misumenoides formosipes)—at Occoquan Bay National Wildlife Refuge. I really like the way that the coloration of the tips of the spider’s leg are an almost perfect match for the spiky thorns of the vegetation. In the second photo, the spider looks a lot like a crab in the way that it is shaped and was moving—it’s easy to see why it is called a “crab” spider.

Changing season

At this time of the year we experience the change in seasons in many different ways. We feel the gradual cooling of the weather. We see the changing colors of the leaves on the trees. We hear (and see) the unmistakable sound of flocks of migrating Canada Geese (Branta canadensis).

Although we seem to have a resident population of Canada Geese in our area year-round, during the spring and summer large flocks of geese fly through our area and it is quite common to hear the loud honking of the geese as they fly overhead. Sometimes they fly in military precision in a v-formation, but more often than not they are in a looser formation, as was the case with these Canada Geese that I photographed last week while I was looking for dragonflies at Jackson Miles Abbott Wetland Refuge in Northern Virginia.

I don’t often see dragonflies perch on flowers, so I was delighted when this female Blue Dasher (Pachydiplax longipennis) decided to rest for a moment on an aster plant in bloom last week at Jackson Miles Abbott Wetland Refuge.

I decided not to crop this photo to show the dragonfly better, because I really like the sweep of bright color on the left side of the image and the more muted out-of-focus colors on the right side. I am growing to love this type of environmental portrait, which goes against my normal approach of trying to fill as much of the frame as possible with my primary subject.

As I was observing some Wild Turkeys (Meleagris gallopavo) last Thursday at Occoquan Bay National Wildlife Refuge, one of them suddenly decided to stretch a bit and flapped his wings. In the past I have seen a turkey extend its wings like this only when running away from me. In this case, though, the turkey went back to pecking on the ground and either was not aware of my presence or was simply not bothered by it.

Perhaps he was just trying to cool off on what was a really hot, humid day.

Swift Setwing dragonfly in September

Posted in Autumn, Dragonflies, dragonfly, Insects, Nature, Photography, Summer, wildlife, tagged Canon 7D, Dythemis velox, Fort Belvoir VA, Jackson Miles Abbott Wetland Refuge, Swift Setwing, Swift Setwing dragonfly, Tamron 180mm on September 9, 2023| 5 Comments »

Do you prefer to live your life widely or deeply? That is a curious question, but it is one that affects the way that many of us approach our photography and our lives in general. Let me reframe the question. Are you always seeking to visit new places to see new things, i.e. living “widely”, or would you rather spend your time in familiar locations with familiar subjects, going back to the same places repeatedly, i.e. living “deeply?”

As you may have guessed, I tend to put myself in the second category. I like to observe the seasonal changes at a few local areas, watching for new species to arrive and to depart (or disappear), observing the changes in the flora and the fauna, and discovering favorite spots for my photography. I am not really consumed by a need or desire to add to my “life list” of birds or insects that I have seen, though I do enjoy visiting other locations.

All of these thoughts were percolating in my brain on Wednesday when I visited Jackson Miles Abbott Wetland Refuge to see which dragonflies were still present. I was particularly delighted to spot several Swift Setwing dragonflies (Dythemis velox). In June 2016 at this same refuge, I first photographed a Swift Setwing—a primarily southern species that had never before have been spotted in Fairfax County, the county where I live—and each year since I have eagerly returned to learn more about the species. For more details on my initial sighting, check out my 2016 blog posting Swift Setwing dragonfly.

It is always tough to frame shots of Swift Setwings, because they like to perch on vegetation that overhangs the water and they face the water. The sun was shining brightly and I was happy to capture a couple of images in which the dragonfly appears to be perching among the clouds. I did try to get down low, but I think the background is a reflection of the sky in the water of the pond and not the sky itself.

For the second image, I was far away from the dragonfly. I couldn’t get a clear shot of the Swift Setwing, so I chose to use some vegetation blocking my view as a framing element in the foreground. I like the way that the image turned out.

Viceroy in September

Posted in Autumn, Butterflies, Insects, Nature, Photography, Summer, wildlife, tagged Canon 7D, Fort Belvoir VA, ironweed, Jackson Miles Abbott Wetland Refuge, Limenitis archippus, Tamron 18-400mm, Viceroy, Viceroy butterfly on September 8, 2023| 4 Comments »

On Wednesday I spotted this beautiful Viceroy butterfly (Limenitis archippus) during a short visit to Jackson Miles Abbott Wetland Refuge. At one end of the refuge, there is a patch of wildflowers and I always make sure to check it out for birds, butterflies, and other insects. I am no expert on wildflowers, but I think the purple plant in the photo may be a variety of ironweed.

As you can probably tell, the Viceroy is considered to be a mimic of the somewhat larger Monarch butterfly. They are pretty easy to tell apart, however, because the Viceroy has a black line across the hind wings that is not found on the wings of Monarchs.

Twelve-spotted Skimmer in September

From a distance, many dragonflies are hard to identify. However, the wing markings on a male Twelve-spotted Skimmer dragonfly (Libellula pulchella) are so distinctive that I could identify this dragonfly immediately when I spotted it yesterday in the marshland at Jackson Miles Abbott Wetland Refuge.

If you take the time to count all of the spots on the wings of the dragonfly, you come up with a number much higher than 12. Why then is it called a Twelve-spotted Skimmer? Someone decided that it was best to count only the dark spots, because only the males generally have the white spots. It is a rare case when gender equality seems to have factored into the name of a species—normally species’ names are based on the characteristics of the male.

Biological imperative

The clock is ticking as we move towards the end of the dragonfly season and I see a lot of mating dragonflies that appear to be driven by the biological imperative of ensuring the perpetuation of their species. Late in August I observed this pair of Blue Dasher dragonflies (Pachydiplax longipennis) at Occoquan Regional Park in the mating position that is sometimes referred to as “the wheel.”

When mating is completed, the female, the lower dragonfly in the photo, will may lay 500 or more eggs by flying low over the water usually near a heavily vegetated pond edge and repeatedly tapping her abdomen to the surface. Once the eggs hatch, the life cycle of a dragonfly larva begins as a nymph that live underwater and eat smaller aquatic insects. The nymphs, also referred to as naiads, live underwater for up to two years and shed their exoskeletons six or more times.

According to an article in Cambridge Day, “When a naiad is ready to metamorphose into an adult dragonfly, it swims to the surface at night. There, it lifts its head out of the water as its body adapts to breathing air, then climbs a plant stem out of the water, where its skin splits behind its head and the adult dragonfly emerges. The adult swallows air to plump up its body and pumps hemolymph, the bloodlike substance of insects, into its wings.”

For more information about the life cycle of Blue Dasher dragonflies, check out these postings at Life on CSG Pond and at Cambridge Day.

Almost monochrome

Posted in Autumn, Birds, Nature, Photography, wildlife, Winter, tagged Buteo lineatus, Canon 7D, hawk, Occoquan Bay National Wildlife Refuge, Red-Shouldered Hawk, Tamron 150-600mm, Woodbridge VA on December 13, 2022| 3 Comments »

So many of my recent photos have been almost devoid of color. We have already entered into that extended season of the year when the landscape turns monochromatic and bright colors have all but disappeared.

Last Thursday, I was thrilled to spot this Red-shouldered Hawk (Buteo lineatus) that was perched motionless atop a broken-off tree. Somehow in the shadows I was able to spot the bird’s shape and correctly identify it as a bird. I am almost constantly scanning the trees for birds when I am out with my camera and will often take a shot of anything that looks remotely like a bird. I will take a look at my shot and sometimes find that it is a photo of a wasp nest, an unusually-shaped branch, or just a cluster of leaves.

Although this image is almost chromatic, there is a slight warmth in the feathers of the hawk that help to separate it visually from the tree. If you look closely at the image, you will also discover some light green color and texture in the lichen that was growing on the bark of the tree.

The beauty of nature in winter is often subtle, but it is definitely there, waiting to be discovered in the shapes and textures that reveal themselves when you slow down and pay attention.

I was surprised and delighted to spot this pair of Bald Eagles (Haliaeetus leucocephalus) perched on a floating log in the waters off of Occoquan Bay National Wildlife Refuge last Thursday. As I draw closer to nesting season, I have been seeing more eagles in couples. Normally, of course, I see them in the trees, but I have gotten used to scanning the water as well—I never know where I might see a perched eagle.

Eagle and grebe?

As I was observing a Bald Eagle (Haliaeetus leucocephalus) last Thursday (8 December) at Occoquan Bay National Wildlife Refuge, it suddenly swooped down to the water and snagged what I assumed was a fish. When I looked at my photos, however, the prey looked like it might be a duck or some kind of grebe. Yikes!

I have read that eagles will sometimes grab a waterfowl for meal, but I thought that was only as a last resort, for example, when the waters at a location are mostly iced over during the winter. At this time of the year, the waters are completely ice-free, so I am not sure what prompted the eagle to hunt for another bird rather than a fish. Perhaps the eagle was feeling lazy or was really hungry and did not want to go to the trouble of tracking and catching a fish.

Some birders on Facebook have suggested that the prey might be a small grebe, possibly a Horned Grebe, or perhaps a small duck, like a female Hooded Merganser.

We seemed to have already moved into the winter cycle of cold, gray days, when the images that I do manage to capture have a real starkness about them. The absence of color in the environment, though, makes any color in my subjects really stand out.

When I visited Occoquan Bay National Wildlife Refuge on Thursday, most of the birds seemed hidden—I could hear them, but for the most part I had trouble spotting them. As I was walking along one of the trails, however, I heard some rustling in the underbrush and watched as a female Northern Cardinal (Cardinalis cardinalis) flew to a a perch amidst the vegetation.

My view of the female cardinal was partially obscured, but I managed to maneuver into a position from which I had a clear view of her head. I really like the way that I was able to capture some of the delicate details of this cardinal, like the tinges of red on the feathers of her crest, the fluffy feathers on her chest, and her extra long claws.

Male Downy Woodpecker

Most of the time when I see (or hear) a woodpecker hammering away at a tree, I can’t actually see the results of its work. Yesterday, however, I managed to capture this shot of a male Downy Woodpecker (Picoides pubescens) at Occoquan Bay National Wildlife Refuge that shows the hole being probed by the little woodpecker. There is a bit of wood in the woodpecker’s beak, but as far as I could tell, he was not successful in locating any tasty insects.

How do I know that his woodpecker is a male? Only male Downy Woodpeckers have the small red patch on the back of their heads that you can see in this photo.

Vultures overhead

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged birds in flight, Black Vulture, Canon 7D, Cathartes aura, Coragyps atratus, Occoquan Bay National Wildlife Refuge, Tamron 150-600mm, turkey vulture, Woodbridge VA on December 8, 2022| 2 Comments »

I often see vultures circling overhead when I am walking along the trails at Occoquan Bay National Wildlife Refuge. Although I have gotten used to their presence, I find them to be slightly spooky and I try to make sure I don’t stand still for too long a period, lest the vultures think that I am carrion.

Most of the vultures that I see are Turkey Vultures (Cathartes aura), like the one in the first photo. Occasionally, though, I also see Black Vultures (Coragyps atratus). How do I tell them apart? As you can see in the second photos, Turkey Vultures have red heads, while Black Vultures have black heads. In addition, the pattern of the light feathers on the underside of the wings of the two vultures is different. Black Vulture have patches of light feathers near the tips of the wings and Turkey Vultures have light feathers along almost the entire length of the trailing edges of the underside of their wings.

Downy Woodpecker in December

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged Canon 7D, Downy Woodpecker, Occoquan Bay National Wildlife Refuge, Picoides pubescens, Tamron 150-600mm, Woodbridge VA, woodpecker on December 7, 2022| 4 Comments »

I had a lot of trouble trying to track this energetic Downy Woodpecker (Picoides pubescens) as it moved about among the branches of a tree last Friday at Occoquan Bay National Wildlife Refuge. It paused for a moment and I was able to capture this image in which it looks like the little woodpecker is posing for me and smiling.

Downy Woodpeckers are the smallest woodpeckers in my area—about six inches in length (15 cm)—and are the ones that I see most often. I am always struck by the high energy level and industriousness of these little birds that seem to be foraging all of the time.

Bluebird and sumac

Posted in Autumn, Birds, Nature, Photography, wildlife, tagged bluebird, Canon 7D, Eastern Bluebird, Occoquan Bay National Wildlife Refuge, Sialia sialis, sumac, Tamron 150-600mm, Woodbridge VA on December 6, 2022| 8 Comments »

When there is an abundance of berries, how does a bird decide which one to eat first? I thought that a bird would select the one that was closest to it. However, when I watched an Eastern Bluebird (Sialia sialis) last Friday in a patch of sumac at Occoquan Bay National Wildlife Refuge, I realized that it had a different criterion for selecting berries.

I captured this little sequence of photos that showed a bluebird reaching down and carefully selecting a single berry that met its unstated criteria. After holding the berry in its beak momentarily, the bluebird swallowed the berry and, judging from the final berry, seemed to enjoy its flavor before choosing another one.

I am absolutely delighted to see bluebirds at this time of the year, when the number of birds has been steadily decreasing. These little birds, along with Northern Cardinals, add a burst of color during the long, gray days of the winter months.
