English: Guatemalan Screech-owl

The Guatemalan Screech-owl (Megascops guatemalae), also known as the Middle American Screech-owl, is a species of owl in the Strigidae family. It is found in forests and dense second growth from Mexico to Costa Rica.[1][2][3] Some authorities include M. centralis and M. roraimae in M. guatemalae, but under the English name Vermiculated Screech-owl. When split, the name Vermiculated Screech-owl (M. vermiculatus) is sometimes used for the population in Costa Rica and Panama, but based on voices all in Panama appear to be M. centralis (with its short-trilled song), while populations in Costa Rica appear to be divided between M. centralis and M. guatemalae (with its long-trilled song).[1][2][3]

With a length of 20 to 23 centimetres (7.9 to 9.1 in), it is a smaller than most other screech-owls. Unlike other owls of the same genus, it has feathered feet. It is dimorphic, with one morph overall grayish-brown and the other overall rufous. The tail is relatively long for an owl, the underside has conspicuous longitudinal stripes and some horizontal stripes. Its face is surrounded by a dark feather edge and it has relatively short ear tufts. The eyes are yellow. The beak is pale olive-greenish in color.
