The Townsend's pocket gopher is a large pocket gopher. The pelage is dark buffy-gray to sooty gray on the dorsum and a rich buff on the venter; the face, nose and auricular patch are black; the feet are dirty gray; and the chin is white. This gopher occurs along the Malheur and Owyhee river valleys in Malheur County and in southern Harney County. Townsend's pocket gophers have been found in alkaline soils along the south shore of Harney Lake and in deep fertile soils near Sod House School near the headquarters of the Malheur National Wildlife Refuge and in Stergen…
This is a bird of riparian thickets, farmlands, and towns. Since 1980, it has been observed almost annually in Harney County, usually in numbers less than five. A pair successfully fledged young near the Malheur National Wildlife Refuge headquarters in 1994. Most Harney County records occur from early April to late October. Away from Harney county individuals have also been seen in the various eastern and southeastern counties of Oregon. Hear the song of the Great-tailed grackle Photo by Kathy Munsel, ODFW
The pelage of this mouse is grayish or brownish dorsally, the venter hairs are white with lead-colored bases, and the tail is light colored. In Oregon, it occurs within the area circumscribed by a line connecting Denio Nevada; Fort Rock, Lake County; Powell Butte, Crook County; Malheur National Wildlife headquarters, Harney County; and Burns Junction, Malheur County. On a daily basis, activity begins with an intense burst during the first light to hours after sunset, and declines to almost nil six hours after sunset, then, especially in summer, increases again before sunrise. The Dark Kangaroo Mouse constructs elaborate nests with…
Western Oregon observers enjoy these large, elegant plovers almost year-round, and as a consequence they are one of the most familiar larger shorebirds. Almost all migrants and winterers visiting Oregon inhabit mudflats and open wet dirt fields. A few can be found on sand beaches and even occasionally on rocks, but the great majority are found feeding and resting on open mud. In Oregon, it is a fairly common to common transient in western interior valleys. East of the Cascades, the Black-bellied plover is an uncommon transient in the Klamath Basin and at Malheur National Wildlife Refuge. In winter it…
A large, long-legged wader distinguished from similar species in a flight by flashing rufous underwings and dark brown primaries. Its feet extend beyond tail tip in flight. Flocks generally consist of fewer than 50 birds on the coast. Juveniles migrate south several weeks later than most adults. After mid-November, a few stragglers are seen until late December. The Marbled godwit is a regular spring and fall migrant on the Oregon coast. Spring migration commences in early April and extends through early June on the coast. Its average arrival at the Malheur National Wildlife Reserve is April 27. Hear the call…
In alternate plumage this striking bird's lower neck, chest, and sides are bright chestnut. Three groups of yellow plumes adorn the sides of the head. Its head and throat are black. This grebe favors areas with much open water surrounded with emergent vegetation. The horned grebe is a rare breeder east of the Cascades. Malheur National Wildlife Reserve averages four to five pairs per summer. It is also rare along the coast in summer and is an uncommon spring and fall transient on lakes, reservoirs, and large rivers west of the Cascades and uncommon to common east of the Cascades…
Inconspicuous and master of stealth, the Least bittern inhabits densely vegetated deep-water marshes, making observations rare and difficult; its call is often the only way to detect this secretive species. The smallest of herons, its long neck and legs make it appear larger. The crown, back and tail of male birds is greenish black; purple-chestnut on female. Neck, flanks, and underparts are brown and white and the wings buff. It is a rare spring and summer resident in larger freshwater marshes of eastern Oregon and a very rare spring through fall visitor in the Rogue and Willamette valleys. At Upper…
One of Oregon's rarest breeders, this distinctive "shorebird" is known for its courtship display flight and loud curlew-like call. it often perches in pine trees or on fence posts adjacent to nesting areas. A small plover-like head and short, strait bill seem out of proportion to its body, which is reminiscent of a small curlew. The Upland sandpiper is a rare breeder in large montane meadows within forests of eastern Oregon. They are almost never observed away form the breeding grounds in Oregon. The Upland sandpiper is an Oregon Conservation Strategy Species in the Blue Mountains ecoregion. Hear the call…
Canvasbacks are large; adults in good condition are as heavy as mallards and second in size only to the white-winged scoter among common Oregon ducks. Drakes have a reddish head and neck; black breast, lower back and tail coverts; nearly white back, flank, and belly, and dark gray tail. The hen is grayish brown with a darker brown head, neck, breast and tailcoverts. It is an occasional summer resident in northeast Oregon, nesting locally only at Ladd Marsh in Union County. It is an uncommon spring and fall migrant in northeastern Oregon and regular in winter and spring on the…
Cattle egrets are the smallest of Oregon's three egret species, with short, stout neck and legs, and white body with orange-buff plumes on the head and nape in spring and early summer. They are named for their association with livestock, consuming insects on their backs or stirred up by their hooves. In Oregon, the Cattle egret is a casual transient in spring in the Klamath Basin and rarely in the Malheur National Wildlife Refuge. The least widespread of the state's egrets during the breeding season; a rare breeder in the Great Basin and a few pairs occasionally nesting at Malheur…
The nasal meow of the Franklin's gull can be heard as it soars above wetlands and meadows, and colonies of this species are reported to be the loudest of all the gulls. In breeding plumage, the black hood contrasts sharply with the white breast and bright red bill. This species depends much more on insects and other invertebrates than do other gulls, and is therefore considered economically beneficial and favored by farmers. The Franklin's gull occurs in the southeast portion of the state in spring and summer, especially Harney Basin. It is rare west of the Cascades. It nests locally…
Known as "bluebill" to most hunters, this species is one of the most abundant and widespread of North American ducks. The lesser scaup is similar to the greater scaup in appearance and habits, but is smaller and lacks the white on the primaries. In the field, however, the black-and-white drakes and brown hens are very similar to greater scaups. The common vocalization is the purr call of the female; drakes are usually silent, but utter a low single-note whistle in courtship. In general, the lesser scaup is more apt to be found in interior or freshwater habitats while the greater…
This pugnacious little wren, formerly known as the Long-billed marsh wren, inhabits cattail, bulrush, and other marsh plants. As the only Oregon species of wren that nests over water, it is easy to identify when seen, but sexes are difficult to differentiate in the absence of song due to similar coloration. This species has long been of interest to behavioral and evolutionary ecologists due to its polygyneous mating system, widespread construction of dummy nests, and the male's complex singing behavior. The Marsh wren nests statewide in appropriate wetland habitats. It is particularly common during breeding season around Malheur National Wildlife…
Wigeon drakes are beautifully marked with white pate, green eye stripe, purplish breast and flanks, white belly and wing covert patch, and iridescent black/green speculum. The grayish hen shows white on the wing covert patch. Drakes give a three-note whistle and get progressively noisier as spring approaches and courting flights begin. Medium sized flocks are common in fall and winter, and like geese, will be found grazing pastures, park lawns, and golf courses. It is a rare to locally common breeder in eastern Oregon and rare in summer in western Oregon. It is a common to abundant migrant and wintering…
This medium-sized, shy grebe has bright white cheeks that contrast sharply against a dark crown and rust red neck during the breeding season. An aquatic bird, it breeds in lakes and ponds, usually in forested areas. In Oregon, it is found in waters with hardstem bulrush intermixed with open water over five feet deep. Five to 20 birds at Rocky Point in the Upper Klamath Lake National Wildlife Reserve form the only consistent breeding population in Oregon. The red-necked grebe reaches its greatest numbers during winter along the coast. The red-necked grebe is an Oregon Conservation Strategy Species in the…
These small, fast flying seabirds are unique among alcids in North America in their use of coastal coniferous forests, primarily old-growth trees, as nesting habitat. Their solitary nests are usually concealed within the forest canopy, and breeding birds are cryptic and primarily crepuscular at nest sites. Because of their secretive behavior and elusive nests, Marbled murrelets were considered the "enigma of the Pacific" and were one of the last ornithological mysteries in North America, as the first nest was not discovered until 1974. Distribution at inland nesting sites is fragmented, as birds occur only in areas where suitable habitat remains…
This small, rich-brown wren is only slightly larger than a quarter, and has a tail quite short for a wren. A quiet observer in the forest will see these birds hop in and out and all over logs, snags, shrubs, twigs, and limbs on the forest floor. It has been said that the song of this bird is larger than the bird itself. The Winter wren breed from Coos County southward and in eastern Oregon in the Blue and Steens mountains. It retreats from high altitudes in winter where snow pack is heavy. Migration probably occurs throughout the state, but…
Bobolinks summer in Oregon's eastern grasslands and meadows, singing what has been described as a bubbling delirium of ecstatic music that flows from the throat of the bird like sparkling champagne. The yellow-brown female, juvenile or non-breeding male may at first appear to be a sparrow, but the breeding male has an astonishing and diagnostic backwards tuxedo pattern of buff on the nape and white rump and scapulars on an otherwise black body. The Bobolink is a regular, locally common breeder at the Malheur National Wildlife Refuge and a few scattered pairs occur in northeast Oregon. West of the Cascades…
