July 8, 2015 – Black-capped Donacobius (Donacobius atricapilla)
Found in marshes throughout much of northern and central South America, these birds were formerly known as Black-capped Mockingthrushes, as they were thought to be related to thrashers and mockingbirds. Their current classification is controversial, although they may be related to Old World warblers. They eat a variety of invertebrates, including bees, wasps, and beetles. Known as very vocal birds, pairs often perform duets, alternating their calls to each other. They build open cup-shaped nests in reeds and grasses and are cooperative breeders. Young birds frequently help their parents raise new broods of chicks.
