FIELD NOTES DOUG BELL DATE: JUNE 1, 1985 LOCATION: TRINIDAD HEAD - cont. pairs visible on western, ocean island. This island would be difficult to visit as it is very steep. Lots of Western Gulls though. On Trinidad head there were very numerous: Rufous-Hummingbirds, American Goldfinches, Brown-headed Cowbirds (parasitize the Goldfinches ?), Barn Swallows, Wrentits. Also saw one Purple Finch, and one non-descript, uniform greyish small flycatcher. Small flocks, of up to 12-15 gulls, cruised past in formation - these are somewhat composed of imm. birds. The imm. seem to be hanging out to- gether, whereas the adults are just in pairs. On beach at Trinidad Harbor - placed trap over dead fish that the gulls had been feeding on. On female Western Gull - who had had possession of the fish, continued to chase chase other birds away from the trap. But she was too cautious to go in - kept avoiding the screen front w/ chute, more-so than other parts of trap. While this bird looked to be a "good" Western Gull, another had grey outer primaries that were barely darker than its' mantle. Most birds of these parts were Western, but some grey influence in individuals evident (i.e.: some birds tend to Glaucous-winged appearance).
