The Piute ground squirrel is the other of the two small gray ground squirrels without stripes or spots. In Oregon, it occurs south of Sheepshead and Cedar mountains in Malheur County. It is a species of the High Desert and commonly occurs in habitats in which the dominant shrub is big sagebrush, saltbush, or greasewood. It is commonly associated with rocky outcrops, levees, railroad embankments, ditchbanks, and sand dunes. Some occur in fencerows and edges of alfalfa and small-grain fields. These ground squirrels are usually active for three to five months each year. They emerge from their hibernacula in February…
A thick body, small head and coloration similar to a killer whale make this dolphin easy to recognize. Dall’s porpoise is mostly black with a large white patch on the belly and flanks. The small dorsal fin is partly white and the trailing edges of the tail are frosted white. About seven feet long and weighing around 400 pounds, Dall’s live only in the north Pacific. Dall’s are the fastest of all small cetaceans and can swim at up to 35 miles per hour, almost as fast as a killer whale. When swimming at the surface they create a characteristic…
Bats are important pollinators and the only flying mammals; they use sound to locate their prey, and they live a long time. Oregon has 15 species of bats, and eight of those are Oregon Conservation Strategy Species. Strategy Species are those having small or declining populations, are at-risk, and/or of management concern. Some of Oregon's species migrate south in winter while some remain here and hibernate. Bats have echolocation which allows them to make high-pitched sounds then listen to the echo of those sounds to locate where objects are. Echolocation helps them find even the smallest insect.
The Ord's kangaroo rat is a medium-sized kangaroo rat with awl-shaped lower incisors. It is the lightest-colored kangaroo rat in Oregon; overall the dorsum is a rich buff with gray overtones. The venter, upper lip, feet and side of the tail are white; there is a white spot above each eye and behind each ear; and a white stripe crosses each thigh. The moustache, eyelids, and ears are blackish. In Oregon, it occurs east of a line connecting The Dalles, Hood River County; Sisters, Deschutes County; and Lakeview, Lake County except in the Ochoco, Blue, and Wallowa mountains. Although occasionally…
The Northern fur seal is the smallest member of the family in Oregon. The flippers are nearly twice as large as those of a comparably-sized individual of any other species of otariid. The ears are cylindrical and the auditory meatus is covered with wax to prevent entry of water. The pelage consists of coarse guard hairs and an exceedingly thick underfur that serves as waterproof insulation. Adult males are dark gray or brown dorsally and reddish brown ventrally; a grayish cape covers the neck and shoulders. Adult females are grayish brown dorsally and reddish brown ventrally. The Northern fur seal…
The Long-tailed weasel is the larger of the two weasels in Oregon, but smaller than the other member of the genus, the mink. Males are considerably larger than females. The head is flattened and somewhat triangular; the body and neck are elongate and almost cylindrical; the legs are short, and the tail is long. The summer pelage is brown dorsally; the venter is yellowish to orangish except for a white chin and sometimes one or more scattered brown spots. The tip of the tail is black. The pelage is molted twice annually. In the Cascade Range and eastward through the…
The Yellow rail is a small, secretive rail that is seen and heard far less than any other rail in Oregon. Males vocalize during the breeding season with a five-note tic-tic, tic-tic-tic repeated incessantly during hours of dark, and call infrequently during the day. The call sounds much like two small rocks being tapped together. Yellow rails are quite small and have a white patch on the trailing edge of the inner wing, more extensive than that on juvenile Soras. Males in the breeding season have a distinct yellow bill and are slightly larger but otherwise sexes are alike. Chicks…
The American badger is a medium-sized, powerfully built carnivore strongly adapted for digging. The body is flattened and the legs are short but stout; the toes of the forefeet are partly webbed and equipped with long, curved claws; the hind feet are shaped like miniature shovels; and each eye is equipped with a membrane that can be extended to cover it. The ears are rounded and densely covered with fur but seem large in comparison with those of many digging mammals. The tail is short and brushlike. Dorsally, the long, shaggy pelage is mottled grayish blending on the venter to…
Features: Blue grouse are large in comparison to most other grouse species. The females are mottled brown, tan, and gray. The males are similar, but with solid blue-gray on the underside and bright orange-yellow combs over the eyes. Habitat: Blue grouse occupy the coniferous forests of western Oregon, the eastern slopes of the Cascades, the Blue Mountains of northeastern Oregon, and the Klamath Basin and south Warner Mountains. Preferred habitat includes timber edges, open timbered slopes, mountain meadows adjacent to springs or other sources of water, and near berry producing areas such as chokecherry thickets. Technique: Effective hunting techniques involve…
The goal of the Oregon Hatchery Research Center (OHRC) is to answer scientific questions related to fish recovery and hatchery programs. Information gained at the Research Center will help answer questions vital to the success of the Oregon Plan for Salmon and Watersheds and implementation of the Native Fish Conservation Policy. The Oregon Hatchery Research Center is a cooperative research project between the Oregon Department of Fish and Wildlife and the Oregon State University Department of Fisheries and Wildlife.
The dusky-footed woodrat is a medium-sized rat-like form with large, nearly naked ears, protruding eyes, and a long tail. The dorsal pelage consists of hairs with steel gray bases, a band of ocherous buff, and a tip of black. Hairs on the throat and belly are white. Although variably in extent, a dusky splotch occurs on the dorsal surface of the white feet. In Oregon, this woodrat occurs from the California border northward along the coast to near Bandon, northward inland through the Willamette Valley and other interior valleys to near Mollala and Monmouth, and northward to Brownsboro, Jackson County…
Peregrine falcons are among the most charismatic and noted of the world's birds. They are described as the fastest animal on the planet, and have been recorded reaching speeds in excess of 240 miles an hour in dives after prey. They are one of Oregon's boldest raptors, and have been observed usurping active Golden eagle nest sites, stealing fish from Ospreys and ground squirrels from adult Bald eagles who stray into their territory. It has, for perhaps 4,000 years, been used by falconers because of its skill in capturing game birds in tandem hunts with humans. Peregrines are medium-sized raptors…
SALEM, Ore. – ODFW staff at the Ashland Boat Inspection Station found golden mussels on a watercraft that was being transported to a new owner from the Sacramento River Delta to Oregon on April 4. The watercraft was decontaminated at the inspection station and all golden mussels attached to the…
With four wing-beats each second pushing them to 62 miles per hour, brant are the fastest and strongest geese in flight and among the swiftest of all large birds. Black brant comprise the vast majority of brant occurring in Oregon. These small geese have smoky black backs and bellies, and dissected white collars and white around the tails provide striking contrast. The black brant can live up to 20 years and are resilient enough to ride out storms on the open ocean. In Oregon, wintering numbers along the coast have seen a 50 percent reduction from previous years due to…
The ringtail is shaped somewhat like a marten with an elongated body and tail of approximately equal length. The ringtail is named for its tail which has has eight dark bands alternating with seven buffy bands. The dorsum is buff overlain with blackish or dark-brownish guard hairs; the venter is whitish or light buff. The face mask is whitish, but the eyes are fringed with a narrow band of black. The toes are equipped with semi-retractile claws, and except for the pads, furred on the ventral surface. The ears are long and set wide apart on a nearly horizontal plane…
A black bear tried its best to get into a Neskowin homeowner's bear resistant trash can. The homeowner then built a small shed to enclose the trash can. The persistent bear left its prints and claw marks on the shed but did not succeed in breaking into it. This resident…
