Striped owl (Pseudoscops clamator)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Strigiformes
Family : Strigidae
Genus : Pseudoscops (disputed)
Species : P. Clamator

Description:

The Striped owl (Pseudoscops clamator) is a medium-sized owl with large ear tufts and a brownish-white facial disk rimmed with black. Its beak is black, and it has cinnamon-colored eyes. It has shorter, rounder wings than most of its close relatives. The upperparts are cinnamon with fine black vermiculation and heavy stripes. The underparts are pale tawny with dusky streaks. It is native to South America, and parts of Central America.

Its systematic placement is not resolved. Different authorities place it in Asio, in Pseudoscops together with the Jamaican owl, or more rarely into the monotypic genus Rhinoptynx.

The striped owl is a relatively large species with prominent tufts of elongated feathers on the crown resembling ears. It is 30–38 centimetres (12–15 in) and weighs from 320 to 546 g (11.3 to 19.3 oz). Its head, back, hot wings and tail are brown with black stripes and small markings while its underparts are buff-colored with heavy black streaking on the breast. The facial disk is pure white with a thin black border.

The striped owl is native to much of South and Central America. Its range is not well known, perhaps because it is nocturnal and not easily seen, but it is known from Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela. It uses a variety of habitats, including riparian woodlands, marshes, savannahs, grassy open areas, and tropical rainforests. It can be found from sea level to 1,600 metres (5,200 ft) and above.

Ferruginous pygmy owl (Glaucidium brasilianum)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Strigiformes
Family : Strigidae
Genus : Glaucidium
Species : G. Brasilianum

Description:

The Ferruginous pygmy owl (Glaucidium brasilianum) is a small owl that breeds in south-central Arizona in the United States, south through Mexico and Central America, to South America into Bolivia and Argentina.

In Central America and South America, it is the most widely distributed pygmy owl and is probably one of the most numerous owl species in those areas. It is found in a wide range of semi-open wooded habitats in these areas.

This species is crepuscular, but often hunts by day. It hunts a variety of birds, lizards, mammals, and insects. The flight is low to the ground and rapid with long swoops.

It can be readily located by the small birds that mob it while it is perched in a tree (up to 40 birds of 11 species have been recorded mobbing one owl).

The ferruginous pygmy owl is small, typically 15 cm (5.9 in), and stocky with disproportionately large talons. The crown has elongated white/buff spots or streaks, the wing coverts have white spots, and the underparts are heavily streaked white. There are prominent white supercilia above the facial disc. There are two eye spots on the nape.

Otherwise, its overall color is highly variable, ranging from grey-brown with a black-and-white barred tail to rich rufous with a uniform rufous tail. Sexes are similar with females slightly larger and often more reddish.
