About Pacific screech owl
The Pacific screech owl (Megascops cooperi) is a medium-sized owl species found across several Central American countries, including Mexico, Guatemala, El Salvador, Honduras, Nicaragua, and Costa Rica. While sometimes considered a race of other screech owl species, its vocalizations are distinct, setting it apart.
Description and Habitat
This owl is characterized by prominent ear tufts and bright yellow eyes. Size varies slightly between its two recognized subspecies, M. c. cooperi and M. c. lambi. The nominate subspecies typically ranges from 23 to 26 cm in length and weighs between 145 to 175 grams, featuring pale tawny gray upperparts with dusky and black markings, and off-white underparts with a herringbone pattern. The subspecies M. c. lambi is slightly smaller, measuring 20 to 22 cm and weighing 115 to 130 grams, with additional dark bars and streaks on its crown. The Pacific screech owl inhabits a wide array of environments, from swamp forests and mangroves to arid woodlands, open country with scattered trees, and secondary forests, generally found from sea level up to elevations of 1,000 to 1,300 meters.
Behavior and Diet
The Pacific screech owl is primarily nocturnal and crepuscular, hunting from low perches in clearings or at woodland edges. It captures prey by pouncing or sallying. Its diet consists mainly of large insects, but also includes other arthropods like scorpions and small vertebrates such as birds and flying squirrels.
Breeding and Vocalization
Details about the breeding phenology of the Pacific screech owl are not extensively documented, but it is believed to breed during the dry season. Nests are typically constructed in tree cavities, frequently utilizing old woodpecker holes, where clutches of three to four eggs are laid. The vocalizations of the two subspecies are notably different: the nominate subspecies has a song described as "prrr pu-pu-PU-PU-PU-pu-pu," while M. c. lambi produces a "staccato croarrr-gogogogogogok." Both also have secondary songs.
Conservation Status
The International Union for Conservation of Nature (IUCN) has assessed the Pacific screech owl as Least Concern. Its estimated population exceeds 50,000 mature individuals, although there are indications that the population is decreasing.
