Blue-black Grassquits (Volatinia jacarina) are also common field and fenceline birds. They are fairly ubiquitous in Costa Rica. A male Blue-black Grassquit performs his display flight & call - flies straight up from his perch on a fence post, about 2 meters, calls, flips over and lands, then repeats this over & over - the flapping sound is the vertical ascent each time.
