Black and White Warbler at Magee Marsh...photos, sketch, and a painting

A female Black and White Warbler (Mniotilta varia) was very thorough in her inspection of this weathered and half-dead tree. She systematically nabbed insects right and left from the nooks, crannies, and crevices of the bark (and I don't think she left any bits of the lichen unturned either :-)...

This beautiful female Black and White warbler foraged for several minutes right in front of me,
letting me marvel at her beauty and industriousness. (These photos go all the way back to May of this year when I was at the Biggest Week in American Birding.)
This post is for my parents, Joni and Jer, my cousin, Curg, and my Aunt Diane. They all traveled up to Maumee Bay State Park this weekend to look for ducks up on Lake Erie. Everyone was in need of Big Water, and Lake Erie, which is only 4 hours away, was the cure. I was supposed to go with them, but work got in the way. Magee Marsh is only 20 minutes from Maumee, so I told them to be sure to stop by the boardwalk. They did...on Nov 5, but it was closed for duck hunting (Nov 5 - Dec 1). So they didn't get to see the beauty of the boardwalk, but I'm going to lure them back up this May when all the warblers are there. That's the best time to go anyway, so I thought I'd post a small taste of what's to come this spring for them! I saw this Black and White Warbler on the boardwalk at Magee Marsh on May 5, 2012. She was just one of hundreds of warblers flitting through the trees that morning...

It was slightly overcast that morning, but the gray light only helped emphasize her beauty!

Black and White Warbler searches in crevices and under bright green lichens looking for insects, spiders, and eggs.
The wet bark on the trees and the overcast skies above showcased the bright green of the lichens.

Black and White Warblers can frequently be seen walking down the trunk like a nuthatch.
...no crevice, hole or crack escapes this little female's attention!

Always nuthatch-like in their movements, Black and White Warblers can crawl up and down and around on a tree...

...sitting pretty! You can tell this is a female Black and White Warbler because her cheek is gray in stead of black.
You can tell this is a female because she has a gray cheek. Males have black cheeks.

I drew this page in my sketchbook that evening from photos I took that day.

Beatrix Potter, Natural History Hero


For Christmas my girlfriend, Cheri, gave me the book “Beatrix Potter, A Life in Nature,” by Linda Lear, and last night I started reading it. I love Beatrix Potter, and pretty much anyone who knows me knows it. Naturally, I'm drawn to her illustrations and children’s stories. Right now I have “The Tale of Squirrel Nutkin” next to my bed because last week I needed a Beatrix word fix:
Nutkin danced up and down like a sunbeam; but still Old Brown said nothing at all.

Like a sunbeam…” So perfect, so simple. However, the other reason I admire her and think of her as a Natural History Hero is her scientific mind and her efforts at habitat conservation and protection. Years ago, while reading about lichens, I was happy to learn Beatrix Potter was an amateur mycologist with original theories on symbiosis, hybridization and lichens…and even better, she was the person who figured out their secret! When Cheri gave me the book, I quickly checked the book’s index and found pages 72-129 are devoted to her scientific research and theories on lichens and the years she spent meticulously painting the region’s fungi. Last night I couldn’t resist jumping ahead to a few of those pages:
Time has been far kinder to Beatrix’s scientific efforts than her contemporaries were. When she tied up her portfolios of fungi paintings with ribbons many years later, she could not have known that her conclusions about the symbiotic nature of lichens and the hybridization of fungi would later be proved and accepted. Nor could she imagine that her watercolours are considered so accurate that modern mycologists refer to them still to identify fungi. Her ephemeral hope that her drawings might some day illustrate a book by an expert mycologist was realized in 1967 when W.P.K. Findlay, a past president of the British Mycological Society, used fifty-nine of them in his volume for the “Wayside and Woodland” series of natural history. No doubt it would have pleased her, but it was, as she feared it might be, a dull book to all but the experts.”
…and from her journal on November 17, 1896:
I think one of my pleasantest memories of Esthwaite is sitting on Oatmeal Crag on a Sunday afternoon, where there is a sort of table of rock with a dip, with the lane and fields and oak copse like in a trough below my feet, and all the little tiny fungus people singing and bobbing and dancing in the grass and under the leaves all down below, like the whistling that some people cannot hear of stray mice and bats, and I sitting up above and knowing something about them.
I cannot tell what possesses me with the fancy that they laugh and clap their hands, especially the little ones that grow in troops and rings amongst dead leaves in the woods. I suppose it is the fairy rings, the myriads of fairy fungi that start into life in autumn woods.
The New York Times on the Web has Chapter One of Liaisons of Life by Tom Wakeford posted. If you're interested, the chapter is a condensed explanation of her life and her scientific pursuits.

...and on the University of California Museum of Paleontology's site, a nice explanation of what a lichen is:
"Lichens are unusual creatures. A lichen is not a single organism the way most other living things are, but rather it is a combination of two organisms which live together intimately. Most of the lichen is composed of fungal filaments, but living among the filaments are algal cells, usually from a green alga or a cyanobacterium.

In many cases the fungus and the alga which together make the lichen may each be found living in nature without its partner, but many other lichens include a fungus which cannot survive on its own -- it has become dependent on its algal partner for survival. In all cases though, the appearance of the fungus in the lichen is quite different from its morphology as a separately growing individual.

The true identity of lichens as symbiotic associations of two different organisms was first proposed by Beatrix Potter, who is best remembered for her children's books about Peter Rabbit. In addition to her books, she spent time studying and drawing lichens. Her illustrations are still appreciated for their detailed and accurate portrayal of the delicate beauty of these bizarre organisms.
