Autillo Flamulado

Identificación

The flammulated owl is a small, nocturnal owl approximately 15 cm (6 in) long with a 36 cm (14 in) wingspan. With such large wings for a small body, they can fly rapidly from tree to tree. Males and females can be distinguished by their weight. Females are larger, ranging from 62–65 g (2.2–2.3 oz) and males are smaller ranging from 50–52 g (1.8–1.8 oz). The owl gets the name flammulated from the flame-like markings on its face.<p>The flammulated owl is similar in appearance to the western screech owl, but is only about one-quarter the mass, lacks large ear tufts (but has small ear tufts that are barely visible), and has dark eyes and a different voice. The elf owl is smaller and the mountain pygmy owl is about the same size. The call is a series of relatively deep, single or double hoots.

Taxonomía

The flammulated owl was formally described in 1852 by the German naturalist Johann Jakob Kaup under the binomial name Scops flammeola . He specified the type location as Mexico. This species was formerly placed with the scops owls in the genus Otus but is now placed in its own genus Psiloscops that was introduced in 1899 by Elliott Coues. The name Psiloscops combines the Ancient Greek psilos meaning "naked" or "smooth" with the genus name Scops, a synonym of Otus. The specific epithet flammeolus is Latin meaning "flame-coloured", "with flame-like markings" or "flammulated". The species is monotypic: no subspecies are recognised.<p>A molecular phylogenetic study of the owls published in 2019 found that the flammulated owl is a sister species to the Puerto Rican owl (Gymnasio nudipes).

Distribución y hábitat

It breeds from southern British Columbia and the western United States to central Mexico. It is a neotropical migrant and winters south of the United States, but also in South Texas, Arizona, and California. Unlike many owls, they are migratory, leaving Canada and the United States in the fall. In the winter, they are found in northern Central America, from southern Mexico to Guatemala and El Salvador. They leave their breeding grounds in August to head to their wintering areas, and then return to their breeding grounds in late April and early May.
