Birds in Winter

      Winter has shown the worst of itself over the past week, so there is not much to report from any one location.This post is a collection of unrelated sightings from a couple of outings, and activities in the backyard where the feeders are well stocked, no matter how deep the drifts or how fierce the wind.

Hillside Park, Waterloo, ON

     We enjoyed a pleasant walk with Judy, but photographic opportunities were not great, due at least in part to the wind adding considerably to the frigid conditions and Miriam was reluctant to expose her fingers.

     A Golden-crowned Kinglet (Regulus satrapa) is a tiny little bird, weighing from 4 - 7.8 grams, (barely more than a quarter of an ounce at best), yet it survives our winters here - a remarkable feat. For a comprehensive account of its survival strategies see Bernd Heinrich's excellent book Winter World.

     Our only decent shot is a dorsal view unfortunately, but it does show you the crown from which the bird gets its name.

     These birds are not easy to photograph under any conditions; they are constantly in motion and usually partly hidden behind leaves.

     American Crow (Corvus brachyrynchos) has little difficulty dealing with winter conditions and exploits every opportunity for food and shelter.

     They come into the city at night to exploit its island heat effect and it is a great spectacle to see them streaming in by the hundreds. By the time they have all settled in for the night it is estimated that around 10,000 birds are nestled in the trees.

A Drive Through the Hinterland

     We set off to see whether we could find our first Snowy Owl (Bubo scandiacus) of the winter, but failed to do so. In fact, we saw few signs of life at all in the cold and snowy landscape that is southern Ontario.

     A Cooper's Hawk (Accipiter cooperii) was conveniently perched on a building not far from the road, and showed no intention of moving.

     It had perhaps recently eaten and was was digesting its meal.

     The wildlife may have been absent but the sparkling magic of the winter landscape was there to bring us joy.

At Home, Waterloo, ON

     The wind was fierce and we stayed inside where we were snug and warm. There was no such luxury for a Hairy Woodpecker (Leuconotopicus villosus), buffeted by the winds, but feeding determinedly on the suet feeder, at times swinging to and fro but tenaciously holding on.

     Who cannot but admire the perseverance and fortitude of birds in winter? 

     Again, let me give a shout out to Bernd Heinrich - "Heinrich is a scientist and naturalist of the first rank, champion ultramarathoner, woodsman of skills, seldom seen in modern times...and a nature writer of uncommon talent," (E.O. Wilson).If you have not read Ravens in Winter you owe it to yourself to do so.

At Home, Waterloo, ON

     In a behaviour for which I have no ready explanation, a White-breasted Nuthatch (Sitta carolinensis) - and possibly two - has been showing an inordinate amount of attention to one of the nest boxes in the backyard. It enters at will, sometimes stays in for a while, exits, and frequently re-enters. We obviously don't watch it all day long, but even based on our observations, there seems to be no discernible pattern to the activity. 

     Perhaps the bird is simply seeking shelter from the wind. This nest box, by the way, was used by Black-capped Chickadees (Poecile atricapillus) during the last breeding season, and they successfully fledged four young from it.

     You will forgive that our pictures are not as clear as we might like, but they are taken through a window often coated with patches of snow.

     Here is an extreme case.

     And here is what it looks like when the visibility is a little better.

     More normal behaviour for a nuthatch is to stash seeds for later retrieval, a hedge against hard times when food is concealed beneath snow and ice.

     Perhaps it says, "Thank goodness for bird feeders and kind humans."

     I suspect it does!

     Every day a dozen or more Dark-eyed Juncos (Junco hyemalis) spend much of their time in our backyard. They are generally the first birds to arrive as the darkness yields to the first glimmer of daybreak.

     I strew cracked corn for the Mourning Doves (Zenaida macroura) but the juncos seem to relish this too.

     Numerically, American Goldfinch (Spinus tristis) is  the most abundant species.

     Downy Woodpecker (Dryobates pubescens) is also a daily guest; today when topping up the feeders three individuals were present.

     You too can enjoy birds in your backyard, and by simple observation learn a great deal about their lifestyle and adaptations to survival in a Canadian winter.

     Other species visit too, but we were unsuccessful in getting pictures. Perhaps we'll have those for next time.
