Sentinels in Saltator atricollis (Passeriformes: Emberizidae).

I studied the existence of sentinels in Saltator atricollis in a 'campo-cerrado' (Brazilian savanna) during the breeding seasons of 1994-95 and 1995-96. Groups of this species consisted of two to seven birds (N = 25). Sentinels were present (mean +/- sd) 62% +/- 9% of the time, and most sentinel bouts lasted from less than one to six minutes (although in some occasions for more than 30 min.). O...
