and then - also soaring around. Good mind today, birds.
Brandts Cormorants are also nesting out on the west
peninsula. They are further down than the Double-vented
cormorants. A cow was inspecting the island. Small
family group of House Finches came by. Counted about
150 gulls out on the western peninsula of Cape Arago
Lighthouse. Also just noticed a ♂ GWC - dark iris, purplish
eyering, P° tips darker than back, but nevertheless lighter than
W's., sitting on nest at start of west peninsula, north
side. Its nest is troaked in an earthen ledge, with root
support about 1 yard below the cliff top. The cliff top is
overgrown. The ♂ GWC has an deep yellow-orange bill,
and its eyerings are somewhat defathered, giving it a
"teary" appearance. This bird was incubating, but
was soon relieved by a ♀ Western Gull - with rather
dark irides, otherwise a perfect WG. They switched at
the nest, then the male GWC brought back nest material
in 2 strips, gave this to the ♀ WG. She rearranged nest
a bit. This is the GWC that I have seen soaring
near here? Watching it soar and gather more nest material
than the sepe. It's P° tips are indeed very light - only a
few shades darker than its' back. Next to the ♀ WG it's back
looks very light, and its bill is duller in color, not as deep orange
as that of its WG mate. Definitely dark irides. Fantastic!
By the way, I put the piping eggs from the trapped
into 2 other nests - one went in a 2 egg nest, and two
eggs went into a one-egg nest that I actually tried to
