P. DeBenedetti 1967 Creagrus Feb. 19 Pinta Suarez, Isla Espanola, Galapagos The chosen posture is: At least 3 different bird are standing [illegible] the head up, neck thin, bill open, slightly above the horizontal. The head slightly forward, copral exposed but against the body. Birds hold this posture for minutes at a time does not seem to be equivalent to gular farming as they bird stand in the shade or next to bird in a normal posture. One girl flew at another a short (10+ ft) distance away, neck forward, bill open, no call. The open bird clearly shows the red mouth lining.
