The Story
I photographed this Blue-black Grassquit (Volatinia jacarina) at the Charca de Guarinocito, near La Dorada, Caldas, Colombia, in February 2020. It is found from Mexico through every mainland South American country, in shrubby weedy fields, field edges and roadsides. It feeds mainly on grass seeds. The male jumps up from a perch again and again while giving a wheezing call, a display that earned it the local name johnny jump-up, though the show also draws predators to nests. During the breeding season, males defend small territories of about 13 to 73 square meters. IUCN lists it as Least Concern.
I used a Pentax K-1 with the HD Pentax-D FA 150-450mm f/4.5-5.6 for this one, at 1/400 sec, f/5.6, ISO 200, +0.3 EV. The lagoon is protected as the Charca de Guarinocito Integrated Management District.
