Nov. 4, 1960 the group of 5 cormorants, I've come to the con-
clusion that the ones below are Pelagics, but the
other 3 are Brandts. A good way to tell the
Pelagics is the shape of the bill. The bill on the
Pelagic is narrow all the way into the head, doesn't
get thicker as it gets near the base, whereas the
Brandts seems to get thicker and change the shape of
the head near the base. More cormorants have
landed in the meantime, and there are at least 10-12
cormorants on this rock, and most of them are
Brandts, I believe. One has a very nice yellow
throat patch that appeared to be feathered, not
naked, so that would indicate a Double Crested Corm.
Just watched a cormorant leave the rock, fly out
about 300 yds., put down in the water. Just made a
beautiful landing up on the rock--he flew in,
glided, put his legs down, sort of popped right on
this narrow little ledge. A young Brandts.
Haven't seen any wingspread yet, but it wouldn't
surprise me if one of these would do it. The one
that just landed is displaying and is displaying a
beautiful blue patch which is unusual for this time
of year. He did this just after he landed. Now
the patch deflates. This shows that this display
can take place any time of year but is more intense
as the breeding season approaches.
