Marshall (1942) Caprimulgus vociferus vociferus Lake Olomoga Frequently seen- could select one in every night of intensive collecting. Could be told by very red eyeshine & always up in trees - sometimes even top or conspic. branches. Nyctidromus almost always on ground & larger, yellower eye. Collected in avenue of trees across grassland, in small tree edge of grassland or marsh, large tree out in "_". Often seen (red eyesline) sitting still for very long time 15-20 min in high dense branches in lg. trees up canyon above camp when looking for owls. Never heard calling at any time. The next commonest Caprimulgiform at the lake, perhaps one to every 30 or 40 Nyctidromus and 4 or 5 to every Texas nighthawk. One flushed in daytime in ravine above spring. Perched lengthwise of branch blended well - flew very rapidly - no white - ♀ collected. l.g. trees in mixed woods; Not in Swamp Forest.
