The barred owl (Strix varia), also known as the northern barred owl, striped owl or, more informally, hoot owl or eight-hooter owl, is a North American large species of owl. A member of the true owl family, Strigidae, they belong to the genus Strix , which is also the origin of the family's name under Linnaean taxonomy .
The largest owls are two similarly sized eagle owls; the Eurasian eagle-owl (Bubo bubo) and Blakiston's fish owl (Bubo blakistoni). The largest females of these species are 71 cm (28 in) long, have a 190 cm (75 in) wing span, and weigh 4.2 kg ( 9 + 1 ⁄ 4 lb).
Much like the burrowing owl and barn owl, the short-eared owl shows a preference for open environments in its modern range, explaining why the species is so abundant in the La Brea tar pits. The fact that this owl is also more diurnal, like the burrowing owl, presents an additional risk as the asphalt is stickier during the warm days.
The La Brea owl has also been found in the Upper Pleistocene asphalt deposits of Carpinteria, California. Oraristrix brea is interpreted as more terrestrial in habits than forest owls because, compared to North American species of Bubo and Strix , it had longer legs relative to its wingspan.
The northern spotted owl has a nearly contiguous range from southwestern British Columbia south through western Washington and Oregon to Marin County, California.The California spotted owl's range overlaps this range in the southern Cascade Range, and extends south through the western Sierra Nevada to Tulare County, with discrete populations in mountainous areas of coastal and southern ...
The northern saw-whet owl (Aegolius acadicus) is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus Aegolius are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some 20 ft (6.1 m) up.
Burrowing owls have bright eyes; their beaks can be dark yellow or gray depending on the subspecies. They lack ear tufts and have a flattened facial disc. The owls have prominent white eyebrows and a white "chin" patch which they expand and display during certain behaviors, such as a bobbing of the head when agitated.
The northern spotted owl was listed as a threatened species under the Endangered Species Act throughout its range of northern California, Oregon and Washington by the United States Fish and Wildlife Service on June 23, 1990 citing loss of old-growth habitat as the primary threat. The USFWS previously reviewed the status of the northern spotted ...
