At certain estuaries and interior alkali lakes, flocks of many thousands of these migrants can be observed swirling around over shallow water, landing to frantically feed, before resuming migration. Falcons often attack Westerns, and their acrobatic, tightly coordinated escape flights are breathtaking to observe. In winter, these small sandpipers are gray above with white underparts. In breeding plumage they have a rich rufous-chestnut back, cheeks and cap, dark-centered scapulars with rufous-chestnut edges, grayish throats streaked with dark chevrons through the flank, and whitish underparts. Longer-billed females generally are larger than males but are otherwise similar in appearance. Along the coast…

Features: These fish have dark blue backs, silver sides and bellies, and very long pectoral (side) fins. Albacore caught off the Pacific Coast are generally 21 to 30 inches long with the largest fish running about 35 pounds. Habitat: Tuna are pelagic species, meaning they spend their lives in the open ocean. Albacore generally show up 15-200 miles or more off the Pacific Coast in mid-July and stick around through September. Albacore are usually found where surface water temperatures are at least 59 degrees Fahrenheit and the water has a distinct clear blue color (this is where chlorophyll levels are…

Wide open spaces generally surround these sparrow-sized, ground dwelling birds. The upperparts are mostly brownish and the underparts are generally buffy with varying amounts of yellow on the throat. There is black on the breast and side of the head, but the most unique features are small black "horns." Females and immature birds are duller. Interesting behavior includes aerial displays and "flight songs" during courtship, and the propensity to forage and loaf along dirt and gravel roads. In western Oregon, it breeds in small, scattered populations throughout the Willamette Valley, with concentrations in the central valley on and near Basket…

Of the three U.S. and Canadian forest hawks known as accipiters, this is by far the most impressive because of its size and aggressiveness. Like others of the genus it is morphologically adapted to maneuvering through forest landscapes and usually uses an ambush approach to capturing prey; although if prey tries to escape, it quickly pursues. From Turkey to Japan, goshawks are favored over falcons for falconry, and a limited number of permits are issued in Oregon for taking goshawks for falconry purposes. The Northern goshawk has short, broad, round-tipped wings and a long tail. It is approximately the size…

The most common whale off the Oregon coast is the gray whale. In addition to the approximately 200 resident gray whales that live nearly year-round off Oregon, a winter and spring migration brings about 18,000 more past our coast. Gray whales are baleen whales (mysticetes). They grow to 50 feet in length and will weigh up to 80,000 pounds; adult females are larger than males, which is common in all baleen whales. They do not have a dorsal fin on their back but instead have a series of knuckles. These whales are mottled gray and are covered with barnacles and…

Terns are generally associated with marine environments and salt marshes, but the Forster's tern inhabits freshwater areas. During the breeding season this graceful bird is eastern Oregon's resident small white tern. Typical of terns, the Forster's employs a dramatic hunting method of plunge-diving into shallow waters to capture small fish, the bird sometimes submerging completely. This is an uncommon but highly visible colonial breeder east of the Cascades. Hear the call of the Forster's tern Photo by Dave Budeau, ODFW

The Great horned owl is the most commonly encountered owl in Oregon. It is a large, stocky, powerful owl with large yellow eyes and distinctive feather tufts or "ears" above the eyes. Plumage color varies from dark brown in western Oregon to pale grayish brown in southeastern Oregon. The throat is white. It is a fairly common permanent resident throughout the state, but generally absent in areas above the timberline. Hear the call of the Great horned owl Photo by Charlotte Ganskopp

This is a medium-sized bat with large, long ears. It is gray, brown, or black and generally active only after full darkness. Townsend's big-eared bat is very vulnerable to human disturbance, and its numbers are declining. In Oregon, it is classified as a State Sensitive Species. It's also an Oregon Conservation Strategy Species in all ecoregions except Nearshore. Never disturb this bat if you are in a cave. Photo by ©Michael Durham

This large brown shorebird is the most wide-ranging of the curlew species. It is distinctive, having contrasting light-brown and dark-brown head stripes and a long decurved bill that it uses to probe for food on coastal mud flats and beaches. It is a common spring and fall migrant in coastal areas although it is also found, rarely, in small numbers inland as well. It is a rare spring migrant in the Willamette Valley with generally about one record annually, typically in late April or early May. Hear the call of the Whimbrel Photo by ©Keith Kohl, ODFW

This active and often unwary woodpecker, the smallest in North America, is generally the most often seen black and white woodpecker in human-settled areas. A preference is shown for decayed wood for nesting, though sound wood is also utilized. Nest sites are usually 10 to 12 feet off of the ground. It is found mostly at low to moderate elevations in deciduous and mixed deciduous-coniferous forests throughout much of the state, and less often in coniferous forests.

The Cordilleran flycatcher was recently designated a species distinct from the Pacific-slope flycatcher with which it was formerly lumped under the name Western flycatcher. The two species are almost identical in appearance, and the population in eastern Oregon is in some respects vocally intermediate between the Cordilleran and Pacific-slope types, so the distribution and status of the Cordilleran n Oregon is unclear. This species generally occurs in drier, higher elevation forests than the Pacific-slope flycatcher and is more closely associated with riparian zones.

Features: Similar to the greater scaup in appearance and habits, but smaller and lacking the white on the primaries. In the field, however, the black-and-white drakes and brown hens are very similar to greater scaups. Habitat: In general, the lesser scaup is more likely to be found in interior or freshwater habitats while the greater scaup is more a coastal bird. Techniques: Scaup are rafting birds attracted to large spreads of scaup decoys. Popular hunting destinations include coastal estuaries and lakes, where most hunters hunt from a boat. However, in the marshes of eastern Oregon, there can be good hunting…

The long-legged myotis lives in forests and comes out early in the evening to hunt. It is a fast flier and will chase insects for a long distance. One baby is born in the summer, and the species hibernates in winter. In general, the long-legged myotis is a species associated with montane coniferous forests, but it also occurs in some desert and riparian habitats. The long-legged myotis is an Oregon Conservation Strategy Species in these ecoregions: Blue Mountains, Coast Range, East and West Cascades, Klamath Mountains, and Northern Basin and Range.

This medium sized, stocky sandpiper is rarely observed away from the rocky coastline as it forages close to the zone of salt spray. Primarily a late fall migrant with the major influx into Oregon occurring the last week in October and into early November. Generally silent during migration and on wintering grounds. Often found singly or in small groups with foraging Black turnstones and Surfbirds. Cryptic plumage makes it difficult to observe as it forages slowly over mussel and barnacle beds in typical sandpiper fashion. Roosts on rocks with Black turnstones and Surfbirds near feeding grounds, just above the spray…
