December 6, 1955, Antofogasta Bay.

General note about these birds. They are certainly "calmed down" since I first arrived. It has been days & days, for instance, since I have seen choking or anything that looked even remotely like pair formation. Mostly lots of late-stage pairing behavior now. (Many of the birds are still staying in Antofogasta at night. Checked this last night).

Have heard one "Aow" note by attacker before attack.

December 6, 1955, Antofogasta Bay and Tocopillo.

The types of birds have remained much the same in Antofogasta ever since my arrival. Lots of Grey Gulls, lots of Elegant Terns, quite a number of Kelp Gulls, and a few (1-4) Franklin's Gulls (all adult). Had brief glimpses a week ago of a smaller tern, possible Arctic Tern (looked very grey - an in non-nuptial plumage). One juvenile Belcher's Gull seen around Nov. 25-26.

Assemblage of birds at Tocopilla, seen Nov. 29, was surprisingly different. Lots of Grey Gulls, and quite a lot of Kelp Gulls, just like Antofogasta. But also quite a number of Belcher's Gulls, both adult & young birds; and quite a lot of Inca Terns (breeding in barges!)
