said the whales have been hanging out in the bay for several months. Mike suggested I try Goose or Sand Island first. We went past Sand Island first, saw that it has a huge Caspian Tern colony (+1000) on its North end, in beach grass, sand habitat. We went on to Goose Island and saw that D-C Cormorants have literally taken over the southern portion of the island. The entire dune/flat area was flattened by cormorants. As we approached the island probably 500 D-C cormorants were scoured up. The gulls seemed to be forced to the perimeters of the dunes for nesting. We didn't land, but went back to Sand Island which lies just SW of Goose, and braces the Hurla entrance. I was dropped off at the N end of Sand Island. Proceeded around the Caspian Terns and down the spine of the island to the first larger gull colony at the start of dune/grass habitat. Set up the blind & watched gulls from 09:00 - 13:00. Most of the birds in my immediate vicinity were of Western Gull morphotypes. These were all nests placed mostly in sand and next to driftwood. If anything, more Glaucous-winged seemed to be nesting up in the tall beach grass, where it is hard to observe birds without an elevated platform.
Some chicks are already present, and some nests appear to be just starting up, especially those in the less superior habitat such as beach riff-raff. When Mike came to pick me up the wind was blowing pretty hard, and it
