Anchitka Island, Alaska (cont.)
also found at the opposite end of
the tunnel [east side of bluff]. Nests
were of both species I believe.
There are a few birds of large body
& bill size which have little or no
apparent red on the face & have only
+ lack the crests on the head
the faintest trace of white on the
flanks. At first it appeared that
these might be Double-crested
Cormorants. However since closer
looks revealed these birds mated to
others with more red or with more
white in some cases & since the
brightness of red on the face varies
considerably, it seemed more likely
that these birds were Red-Faced species,
perhaps 1st year birds
('sub.adults') - but they were nesting.
They tended to be mated to birds
of similar coloration. Several of these
were seen carrying nesting material
to a specific nest, as was also
on distinct red-faced individual.
Nests contained eggs, small young,
or large feathered young. Usually
clutches of 3 to 4. Several dead
nestlings & one adult
Pelagic were seen beneath
the nests.
Pelagic Cormorant - present & nesting
in lesser numbers than Red-Faced
cormorants as noted above. Nests
in the tunnel area were only 10 ft
