[Tweeters] Pigeon Guillemot in Breeding Plumage in Early February?

[Shelley Evans]

During the PSSS Survey yesterday, we saw a pigeon guillemot in breeding
plumage from Point Robinson on Vashon Is.

The cormorants (both Pelagic and Brandt's) at the Vashon Ferry Terminal
were showing some breeding plumage.  I saw the white flank patches on
Pelagic Cormorant, and you could see some of the white, whisker-like plumes
in the faces of the Brandt's Cormorants.  I don't know whether this is
typical for this time of year.

In both cases, it seems like signs of spring and the breeding season to
come.
