Taxonomy and systematics
The long-whiskered owlet was described in a 1977 paper from three specimens collected in August 1976. Though the species somewhat resembles several other small owls, the authors assigned it to a new genus, Xenoglaux, a combination of the
The original authors proposed that the long-whiskered owlet was most closely related to the owls of genus
The long-whiskered owlet is the only member of its genus and has no subspecies.[3]
Description
The long-whiskered owlet is one of the world's smallest owls. It is 13 to 14 cm (5.1 to 5.5 in) long; three individuals weighed an average of 48 g (1.7 oz).
Distribution and habitat
The long-whiskered owlet is found in the Andes of northern Peru. All of the known locations are near the site where it was discovered, Abra Patricia (a pass on the border of
Behavior
Movement
The long-whiskered owlet is a year-round resident throughout its range.[11]
Feeding
The long-whiskered owlet's diet and feeding behavior have not been described.[11] However, one specimen's stomach contained insect remains.[8]
Breeding
Nothing is definitely known about the long-whiskered owlet's breeding biology.[11] Specimens collected between late July and October showed no physiological signs of active breeding, so it is hypothesized that the species breeds between November and June.[8]
Vocalization
What is thought to be the long-whiskered owlet's primary song is "a single, slightly hoarse, hoot, rising then falling slightly in pitch: whoOOo...apparently given in a series of 4–6 notes/min."[4] "It may also give a rapid, low-pitched trill, which is rarely heard."[7]
