All:

On a circuitous way to work this a.m., I found a large gathering of robins
(100+) at Conrose Park, foot of Waegwoltic, Halifax.  They were alternating
between foraging on the grass and eating the abundant (Eur.) mountain ash
berries.  Among them were several very black-backed and black-headed
individuals - the almost complete lack of pale feathering on their throats was
even more evident.  Presumably some of this flock, at least, hailed may have
from their core range in the nothern Ungava Peninsula (Nouveau Québec,
whatever), but not as once designated subspecies "nigridius" or "Newfoundland
robins" (they probably don't breed on the island).  Such birds, however, are
more found breeding more widely - the odd one even in NS, so who knows?

One Blackpoll Warbler continued (as of yesterday) to filch berries from our
porchside yews, but two Baltimore Orioles also eating the berries 21-22 Oct.
haven't been seen since.

Cheers, Ian McLaren
