Blackburnian Warbler
Blackburnian Warblers pick insects and their larvae from high in the tops of both coniferous and deciduous trees, where they often search entire branches from base to tip by hopping and creeping along them, looking up at the underside of leaves and inside clumps of dead leaves when present. They also pluck insects from the underside of leaves by hovering (known as “hover-gleaning”) and occasionally catch insects in flight.
