They can take off and maintain level flight without
dropping like the Brandts and Pelagics seem to do.
I'm down another 3/4 mile or so and I see out in the
water a long line of cormorants, no more than 3 deep
in any place--approximately 50 in this one string.
They don't seem to be doing much; they aren't
oriented at all the same way though they tend to be
orienting east, paddling away from the shore.
Maybe they'll form a fishing flock, I don't know.
Nobody's going up or down. They are evenly well-
spaced in this line which extends for 50 yds. or so.
Very little clumping; there seems to be a good
distance between all the individuals and they're in a
definite line, front moving in one direction.
I noticed when they were sitting on the pilings
there were very few very dark birds, like an adult
Brandts or something. They were a sort of washed-out
black instead of a real glossy black that you find in
the other 2 species. The predominance in the ones
that I saw had a lot of light underneath and were
probably young birds.
