R.K.Selander, 1952 43 Pie de la Cuesta, 20pt., Guerrero, Mexico August 21 Hunted for two hours in the palms and mangroves surrounding the tip of the laguna. Birds abundant. Noted the following species: (see species accounts also) grebe (-sp.?)-2 individuals in laguna; small, about size of pied-bill grebe, possibly longer necked; diving. Brown pelican- lone bird on laguna, near shore; dead bird at edge of laguna; 2 flying along the level just above the breakers. - Cormorant (P. sinocerus?)-one in laguna, swimming very low in water near shore, Not P. uritius I am certain. - Butorides virescens-several in mangroves along edge of laguna. Many chicken-like calls. Hard to get a good look, since they hide in the vegetation. I am not absolutely certain of this identification, so will attempt to get specimens (Yes, see beyond) - Mycteria americana-shot one from top of mangrove tree-only individual seen. - Coragyps atratus-common; perching at tops of palms. - Cathartes aura?-few ? - Jacana spinosa-4 feeding in logs at edge of laguna. - Tern sp.?-one small tern (about size of S. hirundo, but apparently slimmer) flying for out over laguna.
