White-throated Screech-Owl

The White-throated Screech Owl is an owl found in Andes in Bolivia, Colombia, Ecuador, Peru and Venezuela. It is the largest species of the genus Megascops, at 26 cm and 185 grams .

The White-throated Screech-Owl is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

White-throated Screech-owl was recognized as part of an ancient lineage of Megascops – including also the Whiskered Screech-owl and the Tropical Screech-owl which previously were considered to be of unclear relationships – and indeed its call structure is not too dissimilar from the latter. Its distinct coloration, approximated in the Southern Whiskered Screech-owl (Megascops trichopsis mesamericanus), is thus likely the result of strong genetic drift. More

1854, the highly apomorphic White-throated Screech-owl of the Andes was placed in the monotypic genus Macabra. Gymnasio was established in the same year for the Puerto Rican Screech Owl, and the Bare-legged Owl (or "Cuban Screech-owl") was separated in Gymnoglaux the following year; the latter genus was sometimes merged with Gymnasio by subsequent authors. The Palau Owl, described only in 1872 and little-known to this day, was eventually separated in Pyrroglaux by Yoshimaro Yamashina in 1938. More

is also excellent for White-throated Screech-Owl, Cinammon Screech-Owl, Rufous-banded Owl, Andean Pygmy-Owl and other nightbirds like the seldom-seen Andean Potoo. We shall explore the upper tropical and Amazon forest near Tarapoto where we will look for Black-banded Owl, Band-bellied Owl, Tropical Screech-Owl and Ferruginous Pygmy-Owl. Finally we will fly to the heart of the Amazon where we will look for Crested Owl, Spectacled Owl and Rufous Potoo. DETAILED ITINERARY 01. Day Arrival to Lima. More

White-throated Screech-Owl, and the San Isidro “Mystery Owl”; this latter owl is currently being studied and may proved to be a new species. From San Isidro we had planned a day trip down to San Rafael Falls on the 28th to look for foothill birds, but... Things started off well, with a nice singing male Lyre-tailed Nightjar at a stop along the way. More
