[EBB Sightings] GGAS trip to Alcatraz - May 10

Ten members of GGAS joined ranger Christian Hellwig on our monthly Alcatraz
trip.  The Western Gulls have nests with eggs, and are mostly on the large
concrete area toward the west.  Further north, there is a large Brandt's
Cormorant colony, and some already have chicks.  Snowy Egrets and
Black-crowned Night-Herons are also nesting.  We enjoyed watching the birds
defend their territories, welcome mates and build nests.  The list, only 15
species, but almost all nesting, follows:

6 Canada Goose
2 Mallard
25 Brown Pelican
300 Brandt's Cormorant
2 Pelagic Cormorant
8 Snowy Egret
6 Black-crowned Night-Heron
2 California Gull
400 Western Gull
15 Pigeon Guillemot
1 Common Raven
5 Song Sparrow
4 White-crowned Sparrow
1 Brown-headed Cowbird
2 House Finch
