August 14, 2023 - Costa Rican Warbler (Basileuterus melanotis) Found in parts of Costa Rica and western Panama, these warblers live in and around mountain forests. They feed on insects, foraging in the understory in pairs and small groups and often joining mixed-species flocks. Only one of their nests has been described, it was domed with a side entrance and constructed from dry leaves, twigs, live fern leaves, grass, roots, and moss. Females build the nests and incubate the eggs and males help care for the chicks.
