White-throated Screech Owl

The white-throated screech owl is a large member of its genus. It is 20 to 26 cm (7.9 to 10.2 in) long and weighs 130 to 185 g (4.6 to 6.5 oz). It is overall dark plumaged, has a round head with very small ear tufts, and a longish tail. Adults of the nominate subspecies have a dark brown head and upperparts with small blackish, reddish, and white marks. Their flight feathers and tail have narrow darker bars. They have a dark facial disc with whitish marks above and below the orange eyes and a large white area below the bill that in some postures looks like large moustaches. Voice: The white-throated screech owl has several vocalizations. What is believed to be its primary male song is "gruff, barked notes, 'churrochurro-churro-chu chu chu chu'" given for up to a minute. A secondary song is "evenly spaced hoots, 5 per second". Members of a pair sing in duet, with the female having a higher pitch. The female also has various agitation calls.
