Unspotted Saw-whet Owl Aegolius ridgwayi

Rare, small, and compact cute owl of humid pine-oak and evergreen forest in the highlands of Chiapas and Central America. Strictly nocturnal and usually difficult to see. Most often detected by tooting song, which is prolonged, but its song has a variably hesitant cadence. Unmistakable in range, if seen well: note the big head with white eyebrows, golden eyes, and plain buffy underparts.
