A colorful harbinger of spring, the hardy Tree swallow arrives from the south during February each year. It is a highly social species that is usually observed in large flocks often with Violet-green and other swallow species. It is not colonial but several pairs may nest together if available cavities are clustered. The Tree swallow is a bird of open places near water and is seldom seen in residential neighborhoods or built-up urban areas. It is the only swallow that eats berries and small seeds as well as insects. In Oregon, it is a locally abundant summer resident and breeding…

Brown creepers are the only North American birds that rely on both the trunk and bark of trees for both nesting and foraging. They are small birds, about five inches in length, and have a long, slender, down-curved bill used to probe for insects hidden in the furrows of tree bark. Their brown back, streaked with white, makes creepers on of the best-camouflaged girds of the forest. They most often forage upward from the base of a tree, using their long, stiff tail for support. The Brown creeper breeds and winters throughout forested areas of Oregon, from the coast to…

Skulking through wetlands, the American bittern is rarely seen - it has an extremely slow and stealthy walk, and when a threat approaches it freezes and mimics marshland plants with upright posture and beak pointed skyward. These behaviors combined with its cryptic plumage effectively camouflage the bird. However, it is occasionally seen in flight, and its low, gurgling song can be heard over long distances. An uncommon to fairly common breeder east of the Cascades and a rare migrant in Malheur county it has also been noted at mountain lakes east of the Cascades in Lake County. In western Oregon…

At first look, the Willet is a rather drab and nondescript medium-sized shorebird found in wetland habitats and nearby uplands. However, further observation reveals subtle patterning in its relatively uniform grayish plumage and birds in flight expose a distinct, bold white wing bar that contrasts with a black border. Sexes are similar in appearance at all times of the year. Willet are present on breeding grounds in Oregon for a short period of time during spring and summer, but displaying birds are conspicuous and emit a loud and persistent "pill-will-willet" call. These vigilant and vocal individuals often hover overhead and…

One of the most numerous breeding birds in Douglas-fir and true fir forests of western Oregon is the Hermit warbler, yet it is often overlooked. This may be surprising, given the male's bold colors; however, it seldom descends from the higher reaches of the forest canopy. If you are familiar with its song, you can often hear three to five males singing on a spring morning from many places in appropriate habitat. The male Hermit warbler has a bright yellow head, set off by a black throat and nape. The gray back is marked with black stripes that vary in…

A boldly colored medium-sized bird, the Bullock's oriole builds its characteristic hanging nest in broadleafed trees and tall shrubs, especially when the trees or shrubs are spaced widely and situated along the edges of streams and fields. In Oregon, the Bullock's oriole is a rare to fairly common breeder, especially along major rivers and around farmsteads. It is most widespread in southwest and northeast Oregon. In particular, on the Derby Road in Jackson County. It nests primarily in open spaced cottonwoods, maples, and other tall, forking broadleaf trees. The nest is constructed of plant fibers, hairs, fine grass, and moss…

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…

The Juniper titmouse presents the demeanor of a miniature jay with its crest jutted proudly upright. It is a pale gray bird above and underneath, with little or no brown coloration. Songs and calls are useful in locating hidden titmice. The Juniper titmouse occurs in pinyon pine-juniper woodlands in the bulk of its range. This bird is a cavity nester. The nest is often placed in a crevice of a twisted trunk of large, older junipers. It primarily forages in junipers and juniper seed are important in the winter diet. An Oregon Conservation Strategy Species in the Northern Basin and…

Although quite common in the U.S., the Black-crowned night-heron's nocturnal and crepuscular feeding habits can make it difficult to locate. Its habitat consists of marshes, lakes, rivers, and other wetlands, where it feeds mostly on fish. It is a thick-billed, medium-sized, stocky heron with relatively short neck and legs. Adults have a black back and cap which contrast with the pale gray or whitish underparts. Immatures have brown backs with large pale spots and heavily streaked underparts. A distinctive choking squawk call is often heard at dusk. It is a fairly common summer resident east of the Cascades where it…

Features: Sacramento perch are blackish above with about seven vertical dark bars that are irregular in form and position. They are not a true perch, but a sunfish. It is the only member of the sunfish family native to the west coast and, in Oregon, is found only in the Klamath Basin. Sacramento perch are distinguished from the other sunfish in Oregon by having 12 or 13 dorsal fin spines whereas all the others have 10 or fewer. Maximum size in Oregon is about 12-inches in length and a weight of about 3/4 pound, although in California they have been…

Swainson's hawks are medium-sized buteos, smaller than Red-tailed and Ferruginous hawks. Plumage beneath varies along a continuum from very pale to nearly black below. Lighter-plumaged birds have a distinct chest band. They have relatively long, pointed wings that contribute to superior flying skills. The dark flight feathers contrast with paler wing lining in all but the darkest birds. It breeds in the bunchgrass prairies east of the Cascades with the highest concentration in the foothills of the Blue and Wallowa mountains. It prefers open country and has little need for numerous trees since it forages extensively while in flight and…

The exuberant bounding flight, musical calls, and flashy yellow and black plumage of the American goldfinch in breeding-season make them one of the most recognized and welcome of Oregon birds. Found in flocks nearly year-round, these goldfinches are a familiar site in riparian woodlands, orchards, weedy fields, and agricultural land. They are among the last of Oregon's songbirds to nest and are highly nomadic in the nonbreeding season. They may form mixed flocks with Lesser goldfinches and Pine siskins at bird feeders and weed patches throughout Oregon, as well as with Common redpolls some years in northeast Oregon. Their diet…

This largest of Oregon's hawks inhabits the most open country of the state's buteos, and watches over its home range on long, motionless wings for extended periods in search of prey. Ferruginous hawks are sensitive to human disturbance and tend to reside in remote areas. They occur in two color morphs, but dark-morph birds are rare in Oregon. Light-morph birds are white below with few markings except for the ruddy-colored leg feathers. The back and wing coverts are rust colored and the tips of the primaries and end of the tail tend toward dark smoky gray. It is an uncommon…

So familiar is the American crow that it has been said if a person knows only three species of birds, one of them will be the crow. Recognized by its coal-black plumage, fan-shaped tail, and nasal caw call, it is found throughout most of North America, and its seemingly mischievous character has been immortalized in folk tales and fables. These shrewd birds possess a superior intelligence and an ability to learn and make decisions. They are also sociable, joining together in large roosts, especially in fall and winter. Able to thrive in a wide variety of environments, crows are expanding…

Features: Redear sunfish are often confused with bluegill, but differ by having a red or orange border around the black ear flap and by lacking the spot on the dorsal fin and the vertical bars on the side. Habitat: In Oregon, redear sunfish are found only in a few ponds in the Willamette Valley and the central part of the state. In their native range, redear sunfish prefer warm, large lakes and reservoirs and bayous with vegetated shallow areas and clear water. They feed primarily on the bottom and seldom take surface insects. The diet consists mostly of zooplankton, insect…

Features: Warmouth have more of a bass-shaped body and a larger mouth than the other sunfishes, other than the green sunfish. Warmouth are yellowish brown in color with three or four brownish bars radiating back from the eye over the gill cover. They can be distinguished from the green sunfish by the absence of turquoise mottling on the gill cover and the lack of a dark spot at the rear base of the dorsal fin. Habitat: In Oregon, warmouth are present in a few coastal lakes and widely distributed in the Columbia basin, but are not commonly caught by anglers…

Features: Color varies, but walleye are generally dark olive-brown on top grading to almost white below. Walleye have two well-separated dorsal fins; the first fin has a large black spot at its rear base. The opaque eyes, giving the fish its common name, and canine teeth are other prominent features. Habitat: Walleye are found in the Columbia, Willamette and Snake rivers. In the Willamette River, the walleye fishery is generally limited to the section downstream from Willamette Falls at Oregon City, although a few have been documented as far upstream as Dexter Dam. Walleye prefer large, clean and cold or…

Features: Pumpkinseeds may be identified by the orange or red spot on the ear flap and the orange cheeks with wavy blue or turquoise stripes. Color is exceedingly brilliant and somewhat variable; olive to brassy-green above, the back finely dusted with gold or emerald. Habitat: Pumpkinseeds are found in the same habitats and often in association with bluegills. Adults often congregate beneath old deadheads and trees that have fallen into the water. Food habits are also similar to bluegill. They consume large numbers of snails by browsing on the stalks of aquatic vegetation. Techniques: Pumpkinseed are found in many of…
