"What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked." -Aldo Leopold
It is always nice finding your targets on a big photography trip but the icing on the cake is finding the unexpected. That is what happened here when Casey and spent some time at Moro Bay State Park in southern Arkansas. When speaking to a very friendly park ranger, he let us on to where a pair of these birds setup territory and were virtually oblivious to humans. These birds completely ignored us as they flew to and from their favorite perches, often flying mere feet over our heads. We watched the male handoff their insect prey a number of times and even witnessed a copulation, but those photos were ruined by branches.
The Black-and-white Warbler (Mniotilta varia) is another weirdo in the Parulidae family. It is the only extant member of the genus, Mniotilta, and it definitely stands out against the other wood warblers that we find in Missouri. Whereas other warblers flit about the leaves at ends of branches, through bush or along forest floors, gleaning for arthropods, the Black-and-white Warbler finds another niche. It forages by hugging tree trunks and inner branches, much like a nuthatch or creeper. The interesting genus name apparently comes from another of this bird’s behaviors. This name comes from the Ancient Greek mnion, meaning “seaweed”, and tillo, “to pluck”. Apparently, Black-and-white Warblers strip mosses and reindeer lichens to line their nests, which they make in mature forests across much of eastern and central North America.
The Black-and-white Warbler (Mniotilta varia) can be an easy target for the bird photographer, often being seen exposed along inner tree branches.

With the relatively recent removal of the Yellow-breasted Chat from the Parulidae, the title of the largest new world “wood warbler” may very well go to the Ovenbird, Seiurus aurocapilla. The Ovenbird is somewhat of a misfit itself. Seiurus is a monotypic genus, believed to have derived early in the evolution of the family. This pot-bellied, thrush-like bird nests and forages on the forest floor, getting its common name from its nest that supposedly resembles a Dutch oven.
Although the Ovenbird can be easily heard through much of the summer in any large-track deciduous forest, getting good looks and photographs is easiest by waiting to spot them in a migration trap like Tower Grove Park in St. Louis City where these photos were taken.
Getting a photo of an Ovenbird showing its orange crown stripe can be a fun challenge!
There is a singer everyone has heard, Loud, a mid-summer and a mid-wood bird, Who makes the solid tree trunks sound again. He says that leaves are old and that for flowers Mid-summer is to spring as one to ten. He says the early petal-fall is past When pear and cherry bloom went down in showers On sunny days a moment overcast; And comes that other fall we name the fall. He says the highway dust is over all. The bird would cease and be as other birds But that he knows in singing not to sing. The question that he frames in all but words Is what to make of a diminished thing.
“The Ovenbird” Robert Frost
Ovenbirds walk along their environments more often than flying.
The StL birding community is ecstatic about the arrival of of a male Swainson’s Warbler. This bird appears to have set up a territory that it defends and is only a 20 minute drive from the authors home.
The Swainson’s Warbler (Limnothlypis swainsonii) is a very secretive bird whose summer nesting range occurs in the southeastern United States. It requires a habitat of dense undergrowth and heavy leaf litter for foraging and nesting and, in Missouri, this species is rarely found north of the Current River watershed. It’s safe to say that in the St. Louis birding community, the most popular bird of the past week is a Swainson’s Warbler that has apparently set up a territory along the Lost Valley Trail in Weldon Spring Conservation Area in St. Charles County.
If you decide to try for this bird, be prepared and know what the Swainson’s Warbler song sounds like. It may be the only sign you have that you are in his territory!
Named for William John Swainson, a naturalist, illustrator and contemporary of John James Audubon, the Swainson’s Warbler could fit in well in the lush habitat of this section of Weldon Spring C.A. Here it will compete with the bounty of other low-feeding passerines found here like the Ovenbird, Kentucky Warbler, White-eyed Vireo, Worm-eating Warbler and the occasional Hooded Warbler. Like we needed another reason to love birding at this location!
Swainson’s Warbler – not your typical warbler!
The Swainson’s Warbler is definitely not your typical species of wood warbler. The Parulidae family is well known for the gem-like coloration and spectacular patterns of many of it’s species. The Swainson’s Warbler, however, has a color and pattern more adapted to a lifestyle of foraging in the leaf litter and spending time in the dark understory of swamps and bottomland forests. This bird has a brownish back and lighter, white to cream-coloration on its breast. This typical countershading coloration allows it to blend in and virtually disappear within its environment. There is no sexual dimorphism in the coloration of this species – males and females are virtually identical, unlike other species of warblers also found along the Lost Valley Trail like the American Redstart and the Cerulean Warbler.
The bird is rather flat-headed with a much longer and stronger bill than most other warbler species. It is also known for its pink-colored and strong legs. These adaptations are probably helpful while lifting dead leaves and other detritus of the forest floor while it forages for its arthropod prey.
It is this author’s opinion that the song of the Swainson’s Warbler is one of the most satisfying of bird songs. It sounds like it took the stuttering song of the Louisiana Waterthrush (a closely related species) and perfected it. I can still completely enjoy myself just being in the woods with these guys singing. Be prepared for frustration if you are waiting for one of these birds to pop out of the dense understory to get a nice clear look.
Colombia, MO has had one or more Swainson’s Warblers for the past five years or so. Will this species become a regular at Lost Valley Trail? Is this one of the “good consequences” of climate change? It should be mentioned there have been a few reports that there are currently more than one bird along the trail. Some have claimed two males in separate territories and/or two birds spotted at the same location, indicating the potential presence of a female. I have spent four mornings over the past week looking for this bird and have seen no evidence of more than a single male yet, but there is always that potential.
Best of luck to those going to try for this bird. You would be hard pressed to think of a better place to spend some hours on a spring morning.
Thanks for visiting and let me know if you have had success hearing or laying eyes on this bird or if you have had any luck finding evidence of more than the one bird.
This spring has been flying by. With great cool and wet weather, the spring ephemeral wildflower season has been one of the best I’ve experienced and in the past two weeks the bird diversity has been on the rise. Just today, I had a Wood Thrush, a Cooper’s Hawk and a Barn Swallow from my suburban yard alone! This morning I found a Sedge Wren in the grasses at Beckemeier Conservation Area among about half a dozen warblers.
I hope you are getting out to enjoy some of this action and I want to share a few photos of one of my many favorites, this Worm-eating Warbler that is already setting up territory at Bush Wildlife Conservation Area.

This year it looks like the popular roosting tree at the Grafton, IL Visitor’s Center is playing host to this gray morph Eastern Screech Owl. I have photographed red morph individuals in previous years that were using this same cavity. You can find a few photos of those here and here. There have been reports of brown or “chocolate” morphs being found here or in another nearby location over the past couple of years, but as of yet, I have not been able to photograph that color morph.
My friend Dave and I made this visit and were fortunate to find this bird somewhat active. For a Screech Owl in the daytime, this is fortunate indeed. By “active” I simply mean it would move in and out of its tree cavity and open its eyes to have a look around once in a while.

We were told by a local constable that the name they have given the bird was “Winky,” which I find to be pretty apt for an owl. One thing we noticed during this visit is that the unobstructed viewing lanes are becoming harder to find due to the encroachment of the bush honeysuckle growth. Dave and I could only find two lanes that worked well for photography purposes. If I can confirm they do not use this cavity in the summer, I would like to return to do a little landscaping.
While we waited for the owl to return from its hiding inside the tree, we had a nice opportunity to photograph a Pileated Woodpecker that had flown in to forage among the dogwood berries.

May seems such a long time ago. I don’t know how I get so behind on photo processing, but, better late than never. Here is the first of what will probably be three videos with stills of the White-eyed Vireo nest found by Miguel Acosta at Weldon Spring C.A. this past spring. I hope you like it.
As usual, I am woefully behind on processing images this year, probably worse than usual actually. I’ve also not put much work into birds this year, a general trend over the past few years. Too much I’m interested in and not enough time. Anyway, here is some avian miscellany from 2020 so far.

My quest is to get the perfect Cerulean Warbler shot. These are not it, but getting closer. Better luck next year.

I was happy to fins this Hairy Woodpecker nest this past spring, but, unfortunately, the parents never got used to my presence so I didn’t spend much time here.

Back in April, Casey and I visited a hotspot for the small population of Swainson’s Hawks in Greene County. These hawks are rare in Missouri and nesting pairs are limited to the southwestern portion of the state.

While waiting for more interesting subjects, Killdeer can sometimes get close enough to make it worthwhile. This one was strutting in some pretty good light.

Finally, this Red-winged Blackbird was captured establishing his territory outside the Audubon Center in early spring.
