Clarksville MO, Lock & Dam #24 – Bald Eagle – 2021

birds, wildlife, wildlife photography
A juvenile bald eagle coming in for its prey.

We actually had a couple weeks of a deep freeze, old-fashioned winter during the 2020/2021 season. It was enough to get a lot of ice on our rivers and lakes but it didn’t seem to be quite long enough to bring the eagles into Lock and Dam #24 in big numbers. A couple friends and I tried during the last couple days of the deep freeze and although we had fewer than 12 birds, there were opportunities that made it worth our time. Here are a couple photos of a juvenile eagle (a 1.5 to 2.5 year old bird) that I captured as it came to the water to catch a fish that was stunned following its passage through the dam.

A catch!

Check back soon as I will be posting more photos of eagles and other birds that were making their living in the open waters beneath Lock and Damn #24.

Brewer’s Duck

birds, wildlife, wildlife photography
The Brewer’s Duck is a hybrid between a Mallard and a Gadwall

Although I cannot count it as a new species on my lists, I do believe this bird is worthy of a little attention. The “Brewer’s Duck” has been noticed for centuries, even being painted by J. J. Audubon himself. But, he called it the “Bemaculated Duck”, an apparent misspelling of the descriptor, bimaculated, meaning “marked with two spots.” The Brewer’s Duck is an intergeneric hybrid between a Mallard (Anas platyrhynchos) and a Gadwall (Mareca strepera).

This bird was originally spotted at Bush Conservation Area on February 23rd by Michelle Davis and reported via eBird and MOBIRDS. These photos were taken on February 24th.

The Brewer’s Duck is a true blending of its two-species heritage and they apparently are quite variable in appearance.

In the above photo, the blue speculum patch can be seen, coming from the Mallard. The fine lines of the Gadwall can be seen on the breast and sides. The head is a mixture of both species. Some green can be seen towards the back of the head, although this could only be seen at just the right angle to the sun. The bill is also a mix of the yellow Mallard’s and the all black Gadwall. In my opinion, the feet are more reminiscent of the color of the Gadwall’s feet.

A nice comparison of Mallard, Brewer’s and Gadwall drakes.

So far I have been unable to find out much about the Brewer’s Duck from books or internet sources and I have lots of questions. This bird seemed to mostly associate with Gadwalls. Is this common, or does it depend on which species was the mother? Does the parentage have to be directional? Are they fertile? How common are they?

Thanks for the visit!

White-tailed Deer Rut of 2020

wildlife, wildlife photography
A ten-pointer posing for a portrait.

The rut of 2020 turned out pretty well for me. I was able to get to my favorite place for this type of photography five or six times. I tried for a few more days, but weather and flooding caused me to change plans. I didn’t get any high action shots, but I am happy with the portraits I got of some of the larger bucks in this herd.

This smaller eight-pointer has an extra antler growing.
White-tailed bucks will often drool in the heat of the rut.
This “wide eight” knew somebody was watching but never did find me.
A buck looking for just the right scent on the breeze.
This guy thinks he found the one. He chased her into the bush and beyond my sight.
Waiting on the edge of the dance floor.
This location was not the greatest for fall colors, but I lucked into a couple of interesting environmental portraits.
I lucked into this guy walking under the nicest colored tree in the area.

White-tailed Deer of 2020 – Part Three

mammals, wildlife, wildlife photography
A buck with small, deformed antlers. Antler growth like this is usually caused by injury or poor nutrition.

Tonight I’m finishing off the neighborhood deer photos from 2020. This buck pictured in the first two photos was a bit odd. Not just because of the aberrant antlers, but he also did not mind my close approach or my following him as he browsed.

Same oddball buck stretching to reach wild grapevine.

White-tailed Deer of 2020 – Part Two

wildlife, wildlife photography
A fortunate position led to a rather regal portrait for this suburban prince.

A few more white-taileds from August. Have a look at the next three images. I’m hoping someone with some knowledge in the genetics of these guys might have some idea what is going on with the buck on the right. With his rack and size, he obviously has the genes, but he looks so different from what I think we would agree is a more typical buck next to him. In addition to the shapes of their heads and faces, their coats are vastly different as well. Thanks for sending any thoughts you might have about what these difference might be caused by.

A couple of different bucks. These are the largest and most impressive of the lot that I found in the neighborhood this year.
Another look at these juxtaposed bucks.
Another look at the contrasting colors and facial shapes of these two buddies.

White-tailed Deer of 2020 – Part One

mammals, wildlife, wildlife photography
A brave white-tailed deer fawn stands on its own, not concerned by the photographer.

2020 was a decent year for me in finding and photographing white-tailed deer. It started in the summer a I walked the high-voltage line cuts that run through our neighborhood. These turf fields, the wood lots and scrub fields that run along this area and our yards are home to a good size population of these deer. As I get more into landscaping our yard with native plants, I’m sure I’ll develop issues with these guys, but they are a lot of fun to watch and photograph.

Four bucks and a baby.

Typically, summer bucks in velvet are not easy to see in the daytime. They typically stick to a small area, eat the abundant greenery and try not to damage their sensitive new headwear. Suburban bucks are different. In fact, I had much easier times finding bucks this summer in the neighborhood than I did during the rut season when they are typically easier to find and get close to.

I came across this doe early one morning when walking up this gravel trail.
I tell them its not polite to stare but they never listen.
Great light for a portrait.
The back-lighting here causes the velvet of this buck’s developing antlers to glow.
This curious fawn, photographed the same morning as the previous image, actively pursued me and eventually got closer than the minimum focusing distance of my lens!
I found these three in the turf fields later in the day and the season than the rest of their herd. I imagine mom wanted to refuel for as long as she could before heading to the woods.

That’s all for this set. Stay tuned and check back later to see more from the neighborhood this summer as well as images I took during the rut.

Northern Harrier

wildlife, wildlife photography
A Northern Harrier formel glides by, always on the lookout for a small mammal.

Sometimes it’s better to be lucky than good. In fact, with the Northern Harrier, a bird with keen eyesight and talent for being as far from people as they possibly can, I’d say being lucky is the best thing to be.

A female Northern Harrier photographed at Columbia Bottom C.A. in St. Louis County.

During a recent trip to Columbia Bottom C.A., I spotted this formel (an old-school name for a female hawk or raptor) flying back and forth over this small patch of sorghum that was planted near an equipment shed and a small patch of woods that were both near an easy place to park. I doubted I would have the time to get close enough without being seen, but thought I’d give it a try.

Northern Harrier in a typical “V” gliding pattern used to silently move inches above the fields while hunting.

I realized I was in a promising position in which I could move perpendicular to the course the bird was moving. I just needed to make sure I was either hunkered into the scrub-lined woods on the one side, or plastered against the equipment shed on the other. I did this without either being seen by the bird or at least by not being considered a threat.

The Northern Harrier is a rare sexually dimorphic raptor. Males are smaller and colored blue-grey and white while females, like the one pictured here, are full of warm-toned browns.

When I was close enough that I felt I could put my 400 mm f/4 lens to good use, I was ready to shoot the next time she came by. I was able to get some shots on a couple or three passes before she started to move to other locations. Unfortunately, I did not have my camera settings optimized for such an occasion. I left a lot of potential aperture (DOF) and shutter speed on the table (these were mostly shot at ISO 100). But, I am happy with what I was able to get while being sure I did not make the bird too uncomfortable in the process.

The last looks a lot of poor mammals might have – a Northern Harrier overhead.

2020 Insect Wrap-up

macro, wildlife, wildlife photography
This hag moth, or monkey slug caterpillar (Phobetron pithecium) was found on a pawpaw along the Meramec River at Shaw Nature Reserve in early September.

As it seems I say every year, I did not find the time to go out looking for insects as much as I had hoped for in 2020. Here are a few of my favorites from this past season. As always, please correct any inaccurate species identifications if you are in the know. I try my best, but can always be wrong. Thanks.

This punctured tiger beetle (Cicindelidia punctulata) provided quite a lighting challenge for Casey and me.
We found this crane fly in late April. It makes a nice compliment to the early oak leaf.
I tried capturing this greater bee fly (Bombylius major) in mid-air, but failed in that attempt. A portrait shot would have to suffice.
This monarch caterpillar was found feasting on the leaves of swamp milkweed that was in a planter near the SNR visitor’s center.
Sarah and I found this hanging thief robberfly (Diogmites sp.) feeding on a German wasp (Vespula germanica) on the side of our house in July.
While looking for cats at Weldon Spring CA one evening, I was thrilled to find this saddled prominent (Heterocampa guttivitta) that had been parasitized by braconid wasps. This particular species of parasitoid changes the chemistry of the host’s brain so that after the was larvae emerge the caterpillar spins its own silk around the developing pupae and stands guard over them. When touched, the caterpillar thrashes and hisses, guarding them until it starves.
One of my favorite cats to find is Apatelodes torrefacta (spotted apatelodes). They can be found in yellow, or this white form. One day I’ll have to track down an adult to photograph.
A White-blotched Heterocampa (Heterocampa umbrata) shows off its incredible camouflage that allows it to eat as it becomes one with the leaf.
A waved sphinx (Ceratomia undulosa) that has been parasitized by numerous braconid wasps.
In September, I found this nice specimen of a fungus in the Cordycipitaceae family that had attacked a spider. This is most likely Gibelulla leiopus, an obligate parasitic fungus that preys on spiders with an almost worldwide distribution.
Of course I did a little slug moth caterpillar hunting this season. Here I photographed this crowned-slug (Isa textula) catterpillar by using the flash behind the leaf, showing the delicate patterns of the insect.
The highly variable stinging rose slug (Parasa indetermina) is always a welcome find.
The same species pictured above, here showing its bright red underbelly.
I found this spiney oak slug (Euclea delphinii) by searching the undersides of oak leaves at Babler State Park in mid-September.
The skiff moth (Prolimacodes badia) cats are highly variable, ranging from nearly a complete uniform green to being more decorated like this individual.
Here is the same individual as above, showing more of its interesting “senescent leaf” patterning.
A very common site while looking for slug moth cats, this Nasan’s slug moth (Natada nasoni) caterpillar has the egg of a tachinid fly on it. Most likely a death sentence for the caterpillar if the egg does hatch and the parasitoid larvae invades its host.
Only my second find of this species, this inverted-y slug (Apoda y-inversum) was found at Weldon Spring CA in mid-September.

Thanks for the visit and wishing you a great 2021 filled with more insects!

2020 Bird Wrap-up

wildlife, wildlife photography
A Carolina Wren that paused long enough along the Lost Valley Trail (Weldon Spring CA) in early May.

Here’s a bit of a wrap-up on 2020 with a selection of miscellaneous birds that didn’t fit into any other blog posts.

A Kentucky Warbler with prey found at Engelmann Woods Natural Area in May.
This was definitely my year for Kentucky Warblers. In May and June they seemed to be everywhere I went. This one was photographed on my birthday near Greer Spring in June.
I’m always happy to get a photo of Yellow-throated Vireos. This one was photographed along the Lost Valley Trail Lost Valley Trail (Weldon Spring CA) in May.
Sarah and I found some Eastern Kingbirds in May while birding along Hwy 79. These guys were moving from perch to perch among the flowering weeds in ag fields.
The light was harsh, but I couldn’t help shoot these Eastern Kingbirds.
Sarah and I found this Killdeer doing its broken wing routine in May. We looked but could not find any sign of a nest or chicks.
On the same trip as the previous two species, we came across this solo male Bobolink singing. I slowly creeped along the weeds to get close enough for this photo.
This pair of Dickcissel were caught in the act on an orchid hunting trip in mid-June.
A photo taken at August A. Bush Memorial CA in very low light of a Worm-eating Warbler. Always one of my favorites!
A very cooperative Pine Warbler sat for Dave and I during our birthday trip to the southeastern part of the state.
This Wood Duck wasn’t buying me in my kayak and would let me get only so close at Mingo NWR.
While Dave and I were looking for Ammodramus sparrows at Weldon Spring CA, we came across this gorgeous Henslow’s Sparrow.
In September, while waiting at a watering hole in St. Louis County, this Red-tailed Hawk flew in for a drink. If you look closely you can see a prey animal it is carrying – either a squirrel or a mink.
A rare-for-Missouri Western Grebe was found at RMBS in late November.
During the same visit to RMBS, Dave and I found our first American Tree Sparrow of the season.

I likely have several other bird photos from 2020 that need processing, but this is all I have for now. Thanks for the visit.
