Robins are slightly dimorphic in coloration, with the males being
darker on the backs, and of somewhat brighter color on the breast.
In the hand, I think that they can always be reliably sexed. Indeed,
the first flocks of robins to arrive seem to be very brightly colored,
and thus are probably males. In general, in songbirds the males arrive
before the females--presumably to establish territories.
To another matter, Greg Pasquariello writes me asking re. owls at
Amherst Is., Ontario. I shall ask around and write him back, but do not
know much about it. Could any netter with information post it? Greg
plans a trip there at the end of Feb.
