The whiskered screech owl (Megascops trichopsis) is a small screech owl found in North and Central America.
Adults occur in 2 color morphs, in either brown or dark grey plumage. They have a round head with ear tufts, yellow eyes and a yellowish bill. The bird looks very similar to a western screech owl, but has heavier barring on the breast, and is slightly smaller in size. They are 6.3 to 7.9 in and have a wingspan of 17.3 in.
The whiskered screech owl's range extends from southeasternmost Arizona and southwest New Mexico (the Madrean sky islands region) in the United States, southwards through Mexico, Guatemala, El Salvador, Honduras, to north central Nicaragua. [1] Their breeding habitat is dense coniferous or oak woodlands, and coffee plantations usually occurring at higher elevations than the western screech owl.
These birds wait on a perch and swoop down on prey; they also capture targeted food items in flight. They mainly eat small mammals and large insects, with grasshoppers, beetles, and moths making up a large portion of their diet but, they also eat katydids and scorpions. They are active at night or near dusk, using their excellent hearing and night vision to locate prey.
The most common call is a series of about 8 regularly spaced "boo" notes, slightly higher in the middle, slightly lower at each end.
3 to 4 eggs are usually laid in April or May, usually found in a tree cavity or old woodpecker hole 5 to 7 meters above the ground.
There are 3 recognized subspecies: [3]
The eastern screech owl or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls. Although it often lives in close proximity to humans, the eastern screech owl frequently avoids detection due to its strictly nocturnal habits.
The western screech owl is a small owl native to North and Central America, closely related to the eastern screech owl. The scientific name commemorates the American naturalist Robert Kennicott.
The scarlet tanager is a medium-sized American songbird. Until recently, it was placed in the tanager family (Thraupidae), but it and other members of its genus are now classified as belonging to the cardinal family (Cardinalidae). The species' plumage and vocalizations are similar to other members of the cardinal family, although the Piranga species lacks the thick conical bill that many cardinals possess. The species resides in thick deciduous woodlands and suburbs.
The pearl-spotted owlet is a small bird of prey found in sub-Saharan Africa. They belong to the Strigidae family, otherwise known as the typical owls or the true owls, which contains most species of owl. As part of the genus Glaucidium, or pygmy owls, they are commonly referred to as 'owlets' due to their diminutive size. Pearl-spotted owlets are brownish and heavily spotted white, with two distinct black false 'eyes' at the back of their head. They are often confused with an African barred owlet.
The flammulated owl is a small migratory North American owl in the family Strigidae. It is the only species placed in the genus Psiloscops.
The Puerto Rican owl or múcaro común, formerly known as the Puerto Rican screech owl, is a mid-sized "typical owl" in subfamily Striginae. It is endemic to the archipelago of Puerto Rico though it formerly also inhabited the Virgin Islands.
The northern pygmy owl is a small owl native to western North America.
The black-capped screech owl, or variable screech owl, is a species of owl in the family Strigidae. It is found in Argentina, Brazil, and Paraguay.
The bearded screech owl or Santa Barbara screech owl is a small "typical owl" in subfamily Striginae. It is found in Guatemala and Mexico.
The tropical screech owl is a small species of owl in the family Strigidae. It is found in Costa Rica, Panama, Trinidad, and every mainland South American country.
The bare-shanked screech owl is a species of owl in the family Strigidae. It is a large owl that feeds at night in forests and lives in a family size group, even during breeding season. The owl's range is only in Costa Rica, Panama, and far northwestern Colombia. The owl preys on large insects, shrews, and small rodents.
The Pacific screech owl is a species of owl in the family Strigidae. It is found in Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. The Pacific screech owl has sometimes been treated as a race of western screech owl or eastern screech owl but its vocalizations are distinct from theirs. Two subspecies are recognized, the nominate M. c. cooperi and M. c. lambi. The latter has also sometimes been treated as a separate species. The IUCN has assessed the Pacific screech owl as being of Least Concern. Its population is estimated to exceed 50,000 mature individuals but is believed to be decreasing.
The Middle American screech owl, also known as the Guatemalan screech owl or the vermiculated screech owl, is a species of owl in the family Strigidae. It is found from northern Mexico to western Panama.
The rufescent screech owl is a species of owl in the family Strigidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela.
The long-tufted screech owl is a species of "typical owl" in the subfamily Striginae. It is found in Argentina, Brazil, and Uruguay.
Screech owls are typical owls (Strigidae) belonging to the genus Megascops with 22 living species. For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.
The Chocó screech owl is a species of owl in the family Strigidae. It is found from central Panama to western Ecuador.
