Dearborn portion of Detroit River CBC

My first bird of 2016 was an Eastern Screech Owl (Otus asio) found behind the Environmental Interpretive Center on the University of Michigan campus at 5:39 am.  

For the daytime portion of this CBC I count the west side of the Rough River and walked trails for approximately 4 miles ending at the Ford Estate near Evergreen.  It was windy and very cold with snowflakes falling the whole time.  This is very disturbed habitat but typically a good bird or two can always be found.
  

I couldn't believe it when I heard Carolina wren chatter and found the bird perched in the open, quite close and in good light.  As luck would have it, I had to load my camera battery before I could start shooting.  I thought, this bird is going to fly.  But even with all my cold hands fumbling it stayed put, chattering the whole time, and I got about a dozen photos.  These are the nicest shots I have ever taken of a Carolina Wren (Thryothorus ludovicianus).




Next good find was this leucistic robin (Turdus migratorius).  The bird was not moving and all of my photos are very similar.  When the bird flew I stood on the trail checking my photos.  I heard a faint sound behind me and it felt like I was being watched.  I turned around and two deer were staring at me.  They never moved and after taking a couple of photos I continued walking.  Earlier I saw a coyote which was not so cooperative.


White-tailed Deer (Odocoileus virginianus)


A not uncommon sight along areas of the generally muddy Rough River is this bluish-green water.  It is typically accompanied by a sweetish, perfumey fragrance that is neither pleasant nor unpleasant, although the mere awareness that rivers should not smell like this makes it unpleasant.  I find the sight of the water disturbing.  This was a little tributary that fed directly into the river.  Though I have no idea what causes this strange color, it reminds me of the blue Tidy Bowl stuff that people use to clean their toilets.  This same color of water can be found in some Belle Isle waterways. I'll do my best Gail Collins imitation here. People can we all agree that using blue toilet bowl cleaner is bad for our streams and rivers.


In another area of the river I found this attractive, possibly hybrid duck.  Below the duck is with a female mallard (Anas platyrhynchos) for comparison.


Much darker head, bill, feathers and markings, and somewhat smaller, but the bird's vocalization was typical mallard.


The easy identification is melanistic female mallard, but if anyone wishes to venture another guess on this duck's lineage, I'd love to hear from you. 


Terrible photo, but it's always thrilling to see belted kingfisher (Ceryle alcyon) on a Michigan CBC.  My area had two this morning.


Our most underrated bird.  



Along the trails I counted only two cardinals all morning.  That is a very low number given the habitat I cover and that I walk near neighborhoods.  But for my final photo of the morning it was all cardinals (Cardinalis cardinalis) - males and females eating from the grass near the parking lot.

Finally, celebrate the end of 2015 and the start of 2016 by watching Noah Strycker's big year video celebrating 6042 species seen.  Birding Without Borders.  You can also read his blog entries - all 365 (it was sort of like traveling around the world with him) and see his lists - as seen by date and another in taxonomic order.  A truly extraordinary accomplishment.

Eastern gray squirrel with white ear tufts

Visiting friends in Ann Arbor yesterday.  They live in a great area with woods and a tree-filled golf course behind the woods abutting their back yard.  The house has an upper level deck with bird feeders and yesterday the tufted titmice, black-capped chickadees and one white-breast nuthatch were busy.   


Cleaning up the spilled seeds on the deck below was this [probably] juvenile Eastern gray squirrel (Sciurus carolinensis) with white ear tufts.  I looked through gray squirrel photos on Google images and a couple did show squirrels with white ear tufts.  Additionally, there were photos of completely albino gray squirrels.  I took these photos through the picture window with my iPhone camera.


This little squirrel was so cute and the first I've seen with white ear tufts.

What the Eye Hears: Tap Dancing and Bird Song

In the Nov. 30th, 2015 issue of The New Yorker Joan Acocella has an article titled Up From the Hold: the Story of Tap, pages 80-83.  She reviews the new book, What the Eye Hears: A History of Tap Dancing by Brian Seibert.  Apparently there has been very little written on tap dancing and this dance form may be in danger of disappearing from our culture.

Although I'm not knowledgable about any kind of dance, I read the full article probably because tap is my favorite form of dance.  Many years ago I saw Savion Glover's "Bring in 'da Noise, Bring in 'da Funk" and was smitten by this live performance.  Then there are the old movies with tappers like Bill Bojangles Robinson (mentioned in the article), Shirley Temple, Gene Kelly, Judy Garland and many others all thanks to Turner Classic Movies.  I'd be remiss if I didn't mention the great Gregory Hines.

What does any of this have to do with bird song?

The book's title, "What the Eye Hears" ... is what happens when we watch a bird sing.


Early in the article Acocella writes, "And that sensory doubleness, sight combined with sound, makes for a psychological aesthetic doubleness.


I read this and immediately thought of my love of seeing a singing bird. Unless the bird flies first, I have to watch it sing.  It's a thrilling sight. The sight and sound of a bird singing enhances our sensory doubleness.


I don't know about anyone else, but I need beauty in my life.  Seeing and hearing a bird sing ... well, you get it.
