FIELD NOTES Doug BELC DATE: JUNE 1, 1985 LOCATION: Eureka city, Humboldt Co., Calif WEATHER: Overcast, drizzle. TIME: 11:00am I am near the harbor, on same street as the Carson mansion. Viewing boat docks and Indian Island. Does not appear to be suitable nesting habitat on Indian Isl. for gulls. Too much human activity on the few spots that are not covered in Salicornium marsh. LOCATION: Trinidad HEAD & BAY, Humboldt Co., Calif. WEATHER: Overcast, some clearing. TIME: 14:00 - 17:00 Lots of gulls about. From the pier in Trinidad Harbor several pairs of gulls can be seen sitting on the various rocks in the bay. On one rock which is at the eastern end of the boat moorings is a pair which definitely has a nest. One bird is incubating and going thru the motions of sitting on eggs with turning and settling (rocking). The male (larger bird) is sitting on the pinnacle of the rock. This nest might be trapable, but it's hard to tell how level the nest surface is. The nest is on an incline of about 25°, but it may be on a flatter shelf. I may try to trap this pair. Walked around Trinidad head. Good view of ocean islands - lots of gulls, murres, cormorants, sea lions. (Pelagic Cormorant and Double-crested Cormorant). Some Western gulls are nesting on Trinidad Head itself. Saw an adult carrying nesting material. On western side found a gull nest & pair on a cliff. From my position I could look down into the nest 3 eggs visible. Many, (>100)
