A Woodlot in Winter

A Woodlot in Winter
Heidelberg, Ontario
30 December 2012






    Part of the territory assigned to us for the Christmas Bird Count included this woodlot in Heidelberg. Hardwood stands are not especially productive from a birding standpoint at this time of year, but it was a great pleasure to immerse ourselves in it nonetheless. One could not help but be reminded of Robert Frost's iconic poem Stopping by Woods on a Snowy Evening. Despite the inconveniences snow sometimes brings I for one would not like to live without it. Winter brings its own array of charms as does every other season of the year.

Owling

Owling for the Linwood, ON
Christmas Bird Count
30 December 2012

    This morning I joined Fraser Gibson and Ken Quanz at 5:45 to go out and search for Eastern Screech Owls Megascops asio as a component of the Linwood Annual Christmas Bird Count. It was a fine winter morning when we met, with gleaming white snow all around, and the temperature a moderate minus 6.5° C. We set off to visit a series of woodlots along a route we have travelled before (Fraser and Ken more so than I) and we were amply rewarded with no less than ten of these enchanting small owls. Given the agreeable weather, great companions and a plethora of owls I can't think of a better way to start a Christmas Bird Count. I'll look forward to doing it again next year.

A Snowy Morning in
Waterloo County, Ontario
29 December 2012

    The winter weather this morning was delightful, with light snow falling and a relatively mild temperature for this time of year of minus five degrees Celcius. My wife and I decided to go for a drive around the rural roads of the county to see what winter specialties we could turn up. At one point we had the splendid convergence of a Red-tailed Hawk Buteo jamaicensis perched in a bare tree while a Mennonite farmer went by driving a team of horses. The hawk flew shortly after we stopped the car but we managed this sequence of photographs.

Freeze behaviour in Common Redpoll
Carduelis flammea at a feeder

    While watching an aggregation of birds at our feeders, including House Sparrow Passer domesticus, American Goldfinch Carduelis tristis, Common Redpoll C. flammea, Dark-eyed Junco Junco hyemalis and Mourning Dove Zenaida macroura, we watched all of the birds, except for two redpolls, explode into the air.  We have been observing a Sharp-shinned Hawk Accipiter striatus in our neighbourhood and we suspected that its presence was the cause for the rapid exit of the passerines. Quickly this was confirmed as we witnessed the hawk flying over our fence at high speed. What the outcome of the chase might be we have no way of knowing.
    The two Common Redpolls that stayed at their perches on a finch feeder froze immediately. They literally did not move at all and remained that way for several minutes. As soon as they felt it was safe to move they flew away from the feeder not even staying to get a few more seeds. 

                               Common Redpoll "frozen" at feeder

    This strategy obviously worked because the hawk took off after the fleeing birds and seemed not to notice the two redpolls which would have been sitting targets. Based on this observation one would conclude that freezing by Common Redpolls is a successful defence against predation by an accipiter.

American Crow, Howard Nelson

American Crow Corvus brachyrynchos
Night time roosts

    In the City of Waterloo and a few surrounding areas there are major night time winter roosts of American Crows and it is a wonderful sight to see countless streams of birds flying into their favourite roosting trees to settle in for the night. Shining a flashlight into one of the trees at night reveals hundreds of birds occupying every branch.
    I recently came across a poem by Howard Nelson, the final stanza of which captures this phenomenon so beautifully.

Around four o'clock or so they begin to drift in.
The couple walking in the cemetery
where the stones flow from other centuries along the hills
notice how the silence gives way
to a few caws, and then more and more coast in
from somewhere, a steady, uneven stream
and a raucous chorus gathers in the trees.
The man sitting in the dentist chair
waiting for the dentist to appear, stares out the window
and sees the crows riding the air
descending onto the trees across the street,
a haunting sight he hadn't expected here.
And someone driving west through town is amazed
at the swirl of the flock across the winter sky,
hundreds, thousands, of black flecks across clouds
stirred with cold blazing light.
Wow, a natural wonder, he thinks,
the most beautiful thing he's ever seen in this city,
or maybe anywhere, and feels
it's a piece of luck to have crows in your city,
something to be grateful for,
to share the wintry earth with crows.


American Kestrel Falco sparverius

    This is the smallest of the falcons found in North America, but also the most colourful. At this time of the year it can often be found perched on wires at the roadside. This male was photographed in Wellington County yesterday.

White-breasted Nuthatch Sitta carolinensis



    This White-breasted Nuthatch remained in a Sugar Maple Acer saccharum tree in our yard for quite some time this morning and it appeared to us that it was sleeping. Certainly at times its eye were closed or half closed. When it awoke (if in fact it had been asleep) it flew to the peanut feeder for a snack!
