PICTURE OF THE WEEK:


This Mourning Dove was only the second one banded at MBO.  While the bluish
tinge to the crown wasn't particularly strong, the distinct rose colouration on the
throat was enough to lead us to believe it is a male.  (Photo by Marcel Gahbauer)

Notes:  For the first time in a long while, we were able to band twice this week.  Perhaps spring is on the way after all, though MBO remains very much snow-covered.  At least the American Goldfinches are an indicator of the changing seasons, with patches of vivid yellow feathers moulting in.  Three new species for the year were observed this week: Ring-billed Gull, Cedar Waxwing and Red-shouldered Hawk.  Still none of the more traditional signs of spring though, such as American Robin, Red-winged Blackbird, or Song Sparrow.

Banding was fairly quiet, as it appears that most of the birds in the area have figured out that the majority of our nets are quite visible.  We will need to reposition the winter nets a bit next winter to improve our effectiveness.  However, we had several interesting captures this week all the same, among them our first Common Redpoll and second Mourning Dove.  Also of note, a Black-capped Chickadee last seen on October 4.  Such records are always of interest, but especially in this case since this bird has only one leg!  Evidently it has been able to survive a long winter despite that handicap, which is an impressive accomplishment.
