April 28, 2018 – Ringed Warbling-finch (Microspingus torquatus)
These birds in the tanager family are found in semiarid grasslands, open woodlands, and shrublands of central Bolivia, western Paraguay, and central Argentina. They mostly eat arthropods during the breeding season, along with some seeds, foraging mostly in vegetation and only rarely on the ground. Breeding from late October to February, they build open cup-shaped nests from plant fibers and hair. Though only the females incubate the eggs, both parents feed the chicks.
