March 29, 2024 - Sharp-billed Canastero or Lesser Canastero (Asthenes pyrrholeuca)
These birds in the ovenbird family are found in shrublands, grasslands, wetlands, and other open habitats. Breeding in southern Argentina and Chile, part of their population migrates as far north as Uruguay, Paraguay, and Bolivia for the winter. They eat arthropods, foraging alone or in pairs mostly in low vegetation and often joining mixed-species flocks. Their round nests with side or top entrances are built in bushes or on the ground from small twigs and lined with soft plant material, hair, and feathers. Females lay clutches of two to four eggs.
