March 6 on board "Golden Bear", Guayaquil to Cocos Islands. Snowy Egrets, Laughing Gulls, Brown Pelicans & large shoatrids were conspicuous on close. There were a # of Sandwich Terns on the bows as we went out and I saw 1 Royal Tern flying past the ship. As the river became wide I spotted two large hawks, dull brown with black flight feathers, very broad winged and short tailed. [illegible]. White Ibis were quite conspicuous here, flying across the river in groups of 4 to 8 and scattered single birds were present as well. The Grey headed Gulls stayed with the boat for only a little ways beyond the mouth of the bay and the Laughing Gulls followed us way out, although not out of sight of land. Frigate birds and Brown Pelicans were fairly common in the bay, feeding in large flocks near the fishing boats with large groups of Laughing Gulls. Saw 4 Peruvian Boobis, Sula variegata. They look like a cross between Masked and Blue-foot, a shimmering white head with a pale bluish iris, dark half mask, and a sharply set off checkered dark brown (or blackish) mantle. The tail was slate. Most were sitting on the water. As we got farther out we saw over 100 Blue-footed Boobis, and the contrast between the species was marked. The latter has large white patches on the back & the top of the head always looks dirty colored, even on very pale birds. After abou
