Шиферный виреон Vireo brevipennis

Handsome but often elusive small vireo of brushy woodlands, tangled thickets, and forest edges in highlands and foothills; endemic to southwestern Mexico. Tends to stay hidden, usually rather low within vegetation, and does not join mixed-species flocks. Moves sluggishly, holding its tail cocked and making short sallies for fruit and insects. Note piercing white eyes, lime-green cap, and yellow-edged wings and tail offset by slaty blue-gray face and body.
