C. Koford 1957 Birds - General 4 February 1957 Pacheca Is, Pearl Islands, Panama made deep rattle in bladder at times. Opposite side of Pacheca had mostly gently sloping sandy beach. Adjacent rocky Pachequilla had many boobies & pelicans perched, but no nesting evident near. This island had much Boobys but also spring coster, & general aspect was very dry. Perhaps no water on islands. On south we saw large gray bottle-nosed porpoise about 6 x 4', a large manta-type ray which kept clear of water again & again. Royal terns occasional, & 2 or 3 petrels seen. Many laughing gulls. The trip from Mire Dock at F.T. Amador required 3 1/4 hrs. each way, mostly into wind on return trips. We caught 2 jack about 2' long near Pachequilla. Colón to Portobelo Colón, Panama 9 February 1957 Leaving Colón to Portobelo in early morning I saw few sea birds - a few terns & perhaps 2 apparent procellariforms. Large swells, & windy. At Portobelo bay cold caged suff- nions (thick-lilled). // We found two nearly fledged carag-ops Baldc vultures in a cave at side of high part fort. Cave 8' high x 10' wide, & birds reticled into arm 2' wide x 4 ' deep. No regurgitation noted, but hessed. Down dark pastly gray.
