English: Whiskered Screech-owl

The Whiskered Screech-Owl, Megascops trichopsis, is a small scops owl.

Adults occur in 2 color morphs, in either brown or dark grey plumage. They have a round head with ear tufts, yellow eyes and a yellowish bill. The bird looks very similar to a Western Screech-Owl, but has heavier barring on the breast, and is slightly smaller in size.

Their breeding habitat is dense coniferous or oak woodlands, and coffee plantations usually occurring at higher elevations than Western Screech-Owl. It ranges from southeasternmost Arizona - (the Madrean sky islands region), in the United States to north central Nicaragua.

These birds wait on a perch and swoop down on prey; they also capture targeted food items in flight. They mainly eat small mammals and large insects, with grasshoppers, beetles, moths making up a large portion of their diet. They are active at night or near dusk, using their excellent hearing and night vision to locate prey.

The most common call is a series of about 8 regularly spaced “boo” notes, slightly higher in the middle, slightly lower at each end.

3 to 4 eggs are usually laid in April or May, usually found in a tree cavity or old woodpecker hole 5 to 7 meters above the ground.
