Wildflowers of Occoquan Bay National Wildlife Refuge / July 9, 2019 by Todd Henson

All the flowers in this post were found while hiking the trails of Occoquan Bay National Wildlife Refuge, located in northern Prince William County, Virginia. This location contains a variety of terrain such as wetlands, fields, and forest, providing home to a large range of beautiful wildflowers. Most of the flowers are small and in small groupings and can be found along the edges of the different trails.

This initial grouping of flowers were all photographed on the same day in early June, but I hope to update this page over time adding new flowers found on the refuge.

One Morning at Occoquan Bay National Wildlife Refuge / July 2, 2019 by Todd Henson

Periodically I like to share a sampling of what one can see on a single visit to locations I enjoy. On most visits I don’t have any goals other than to enjoy the hike and see and photograph as much as I can. I accept what nature provides. And then I gather together what I’ve seen and share it with you.

Today’s post is about an early June morning spent hiking at Occoquan Bay National Wildlife Refuge, a hidden gem in northern Prince William County, Virginia. It’s located at the point where the Occoquan River flows into Belmont Bay, and then into Occoquan Bay, before merging with the Potomac River. It contains a variety of terrain and habitats, with trails along the waters edge, through wetlands, across grass fields, into the woods, and beside ponds.

Below is a small sampling of what I photographed on that morning. Click on any of the photos for a larger view.

Flowers

This can be a great location for photographing wildflowers throughout the year. They border many of the trails, so you don’t have to go far to see them. Do be careful, though, if moving into the grass and brush beside the trail. Some years ticks are plentiful here, so carry bug spray and check yourself after each hike.

I plan on sharing more of the flowers in a future post, but today I’m sharing a bright pink Virginia Rose, a small cluster of Hairy Skullcap, and an American Water-willow. Many thanks to Steve Gingold for identifying the American Water-willow (USDA profile of American Water-willow / Lady Bird Johnson Wildflower Center profile of American Water-willow). Check out Steve’s blog for some great photography and education related to nature and the outdoors.

Butterflies

If you want to photograph butterflies it’s easiest if you can get here first thing in the morning, before the butterflies have become more active. But with a little patience you can still photograph them later in the morning or throughout the day. Those in this post were photographed between 9 to 10 in the morning.

A Skipper butterfly resting on grass. I don’t know the specific species of Skipper, but if you do let me know.

Many of the butterflies would fly away anytime I approached to photograph them. But occasionally one would sit still long enough for me to capture a few pictures. The Monarch was a challenge. It kept moving. The Skipper was a little easier to photograph, sitting still for a brief time before disappearing. The Zebra Swallowtail was a complete joy to photograph. It sat very patiently as I approached, letting me capture a number of photographs before moving on.

Reptiles & Amphibians

This is a perfect environment for a variety of reptiles and amphibians, so keep your eyes open while hiking. The first we found was a very small young Eastern American Toad, at least that’s what I think it is. It could be a Fowler’s Toad, as these do sometimes resemble one another. Let me know if you think I’ve misidentified it.

Further on we encountered two different snakes. The first was a Northern Watersnake feeding at the edge of the water. I shared a number of images of this watersnake in last week’s post. Not long after this we encountered a Northern Black Racer along the side of the trail. Whereas the watersnake didn’t react at all to our presence, the racer was very watchful, flicking its tongue, getting our scent as we stood around watching it.

Not long after this we ran into a Southeastern Mud Turtle trying to quickly get back to the swampy area just off the trail. I barely had time to snap a photograph before it was back in the brush.

Mammals

I’ve been fortunate to see many species of mammals here over the years, such as Coyote, Red Fox, White-tailed Deer and Northern Raccoon. On this particular day I photographed two very different species. One was an young Eastern Cottontail Rabbit just off the trail. It froze when it saw us, hoping we couldn’t see it. We just stood there, quietly, until it grew used to us and went back to eating the greenery on the ground. I love watching these rabbits.

The second species was a most curious one, some form of mouse. It’s the first time I’ve seen one of these at the refuge. I don’t believe it’s native to these parts, and appears to have washed ashore. But it just goes to show, you can see all sorts of crazy and wonderful wildlife while hiking Occoquan Bay National Wildlife Refuge.

Parting Thoughts

This was a small sampling of what you might find at Occoquan Bay National Wildlife Refuge. There are so many other species to see here, whether they be insects, reptiles, or wildflowers. It’s also a good birding location, and in fact is a great place to see nesting Osprey and Bald Eagles.

One drawback during parts of the year are the biting insects. The hot humid months of summer can be miserable in parts of the refuge, especially those that border wetlands areas. And ticks can be very bad some years. So don’t forget your bug spray, and again, check yourself thoroughly after each hike. But don’t let this scare you off. This refuge has a lot to offer a nature lover. Check it out if you’re in the area.

One Morning at Dyke Marsh Wildlife Preserve / May 28, 2019 by Todd Henson

One recent morning I found myself walking through Dyke Marsh Wildlife Preserve with family and friends. I don’t get to this particular location too often, which is a shame, as it’s a beautiful little spot. It resides on a fairly small tract of land along the Potomac River just south of Alexandria, Virginia, and borders a local marina, so you can observe both wildlife and people on various sorts of watercraft.

I photographed anything that caught my eye, and this particular day it amounted to a nice selection of subjects, from plant life to wildlife to sailboats. Below are a selection to give you a feel for some of the opportunities this preserve offers.

Birds

A male Red-winged Blackbird perched atop a dead tree.

One of the more common inhabitants of local wetlands are Red-winged Blackbirds. The males are easy to identify by the patches of red, and sometimes yellow-white, on their shoulders. This particular blackbird kept flying back and forth between perches.

An adolescent Common Grackle resting on a fallen tree.

Another very common bird in this area are Common Grackles. I saw an adult fly off, very easy to identify because of their very striking eyes. Just afterwards I noticed movement down below and saw an adolescent Common Grackle perched on a fallen tree. This may be the first of these I’ve photographed, and if not for having just seen the adult I might have had a harder time identifying this young grackle. It doesn’t yet have the distinctive eye color of the adults, and its plumage hasn’t yet gained the iridescent quality it one day will.

A male Orchard Oriole far off in the distance. This photo is cropped to the extreme to let you see this beautiful bird.

A species I don’t see as often is the Orchard Oriole. This particular very colorful male was quite a ways off. I saw a streak of color and aimed my lens in that direction. I knew I couldn’t create any interesting artistic photographs from this distance, but I always try to capture photographs of different species. This photo is extremely cropped to zoom in on the bird and show you what it looks like.

A scruffy looking Yellow-shafted Northern Flicker.

On the way out of the preserve I noticed movement high up and saw a woodpecker perched at the top of a dead tree. At first I wasn’t sure of the species. It looked very scruffy with what appeared to be almost dirty feathers. But after seeing the red patch on the back of its head and the yellow in its wings I was able to identify it as a Yellow-shafted Northern Flicker. I’m not sure if it’s an adolescent, or if it may be molting. It’s plumage just didn’t look as nice as I’m used to seeing. It made all sorts of interesting movements while preening, and I’ve shown a couple here.

A Hairy Woodpecker perched atop a dead tree.

Just after the flicker flew off another, smaller, woodpecker flew in to take its place. This one was a Hairy Woodpecker, and it proceeded to preen itself as the flicker had, though not in quite as interesting a fashion.

Mammals

A posing Eastern Gray Squirrel. They may be common, but I still enjoy photographing them.

The most common mammal to be seen in these sorts of locations are probably Eastern Gray Squirrels. And as common as they are I still find them a fascinating species that I love photographing. I really liked the pose of this squirrel as it sat atop the remains of a downed tree looking out over a small clearing in the woods beside the trail.

Reptiles

The front portion of a Black Rat Snake resting just off the trail.

This preserve is home to several species of snake, one of which is the Black Rat Snake. We saw two of these this trip, though I only photographed this one. I wasn’t able to get the entire snake in the frame, so this photo is just the upper portion.

A Five-lined Skink resting atop a wooden post.

Lizards are also abundant in these parks. The most common species is probably the Five-lined Skink, which is what all these photographs are of. We found one skink resting on the top of a wooden post by a bridge over some water. It was resting, completely indifferent to our presence. Many lizards I’ve encountered will run off before long when they realize you’ve noticed them, but not this one.

A male and female Five-lined Skink. The male is in the background, with a larger head and redder face. The female is in the front, with a smaller head and more orange/yellow face.

A juvenile Five-lined Skink, darker than the adults with a bluer tail. Click on the photo to see a larger view, then look closely just to the right of its front leg. It has a tick embedded on its back.

On the way out of the park we saw a few more. Two adults were hanging out together. The male has the larger redder head. And we saw a juvenile Five-lined Skink, which is darker than the adults. This poor thing was host to a tick. Click on the photo for a larger view, then look on its back near its front legs. This is the first time I’ve seen a tick on a reptile.

Plants and Fungi

A blooming Yellow Flag Iris. These were all over the wetlands.

The water throughout the wetlands was full of blooming Yellow Flag Iris, absolutely beautiful yellow flowers. Most were in the later stages of blooming, beginning to lose petals. But I found one that still looked reasonably nice.

A cluster of fungi growing on a log just off the trail.

And of course, you can find fungi and mushrooms almost anywhere. This small patch of rather large ones was growing off a fallen tree. I’m unsure of the species.

Watercraft

Dyke Marsh has a trail that leads out onto a small boardwalk on the river. On one portion of the boardwalk we saw this lone moored sailboat in the Potomac River, with very small amounts of mist still hovering around the far shore. We also watched a number of folks in kayaks maneuvering through the narrow channels of the wetlands. It looks like a great way to see things we might not be able to from the trail.

Parting Thoughts

This is just a small sampling of what you might find at Dyke Marsh Wildlife Preserve, or in many of these sorts of locations. I love visiting these locales as there’s always something to see, even on slow days.

If you do ever happen to visit Dyke Marsh be aware the trail can flood. It is a tidal wetlands and the water level of the Potomac does vary quite a bit. When we visited there were large flooded patches, but not so much we weren’t able to slog through them to the boardwalk.
