Endemic Bird of the Day: Puerto Rican Screech-Owl
The Puerto Rican Screech-Owl (Megascops nudipes) is a small owl endemic to Puerto Rico. It is dark brown above and white below with brown streaks on the breast, and prominent white eyebrows. It is about 23- 25cm in length and weighs only 140g, as much as a cup of flour or an adult hamster. There are two color morphs (forms): brown and rufous (reddish-brown). There is also a rare grey morph that can only be found in dry forested areas. It’s scientific name nudipes refers to this owl’s unfeathered legs and feet, which is rare for most owls. Males and females look alike, but females are a bit heavier than males.
The Puerto Rican Screech Owl can be hard to see because it is completely nocturnal and spends the day resting—camouflaged in thick vegetation. Listen out for its call—low-pitched, tremulous trills and a descending whinny. It also gives jumbled hoots and cackles that sound monkey-like. Locally it is known as the “Cuckoo Bird” because of the loud coo-coo sounds it makes. When alarmed, it will elongate its body and raise feathers to form small “ear” tufts.
This owl is common in forests and thickets in montane and coastal zones throughout the whole island of Puerto Rico. It nests inside natural tree cavities from April to June, usually laying one or two eggs. It hunts rodents and small prey, like lizards, coqui frogs, and insects; cockroaches, crickets, grasshoppers, mantis, beetles, weevils, moths and caterpillars, and scorpions. Like other owls, the Puerto Rican Screech-Owl uses its acute hearing and sharp night vision to locate and catch its food. The Spanish name of the species “Múcaro” is also the Taíno word for owl.
The Puerto Rican Screech-Owl previously inhabited the nearby islands of Vieques and Culebra, as well as the US Virgin Islands, but searches for a number of years have failed to find it. It probably went extinct on these islands due to extensive destruction of native forest habitats for agriculture in the early 20th century. Egg predation by the Pearly-eyed Thrasher may have also played a role.
The natural history of this amazing endemic owl is poorly known. Future research should focus on its diet, breeding behaviour, reproductive success, dispersal, and life span. Learn more about this species, including its range, photos, and calls here.
