Scientific Name: Uria aalge
Range / Habitat: Exclusively marine, breeding along sea coasts on rocky cliffs and offshore islands throughout the subarctics. In winter, generally pelagic in the same waters.
Field Notes: Medium-sized waterbird with black to dark-brown head, neck and back. White underparts with some dark streaking on the flanks. Bridled or ringed morph, restricted to the Atlantic, has white eye-ring and post-ocular stripe. Non-breeding adults have white on face and throat. Thick-billed Murre has a white line on the gape, is blacker on the back, and lacks streaked flanks. Razorbill more stocky, with stouter bill lined in white.
Personal Notes: Seen huddled in large clusters against the wind on the Latrabjarg cliffs in western Iceland.

Steller's Jay
Scientific Name: Cyanocitta stelleri
Population Estimate: 4.4M
Range / Habitat: Year-round in montane evergreen forests of western North America, Canada and Mexico.
Field Notes: Noisy, inquisitive and conspicuous like most jays. Coloration is quite dark -- black head and neck with crest and bright blue body. No white markings.
Personal Notes: Richard had been trying to get a photo of this bird for some time. We were finally rewarded at Barr Camp on Pike's Peak. A fitting end to the summer in Wyoming (bottom photo). The top photo was from a group of more subdued jays in Apache-Sitgreaves Forests in Arizona and better demonstrates the plumage and crest.

Canada Goose
Scientific Name: Branta canadensis
Range / Habitat: Wet environments year-round in the middle latitudes of US. Summers up through Canada and Alaska, winters extending down to souther US and parts of Mexico. Introduced in parts of Europe and New Zealand.
Field Notes: Large, noisy waterfowl with long neck and high rump profile in water. Head, neck are black with white cheek patch. Back brown, belly and rump white. Brent Goose has shorter neck and white neck ring, not cheek patch.
Personal Notes: These birds are ubiquitous in Minnesota, so much so that we never photographed them until we were about to leave. We were startled to find them in New Zealand, where introduced and much more wary than in the States.

Red-necked Grebe
Scientific Name: Podiceps Grisegena
Population Estimate: 200K - 300K
Range / Habitat: The two subspecies of the red-necked grebe have distinct ranges. The North American and east Asian subspecies, Podiceps grisegena holboelli, is found in western Canada and the northwest USA, as well as eastern Russia, northeast China and northern Japan. In North America, the red-necked grebe breeds in Alaska, Yukon Territory and the Northwest territories, east to southwest Quebec, and south to Oregon, Idaho, Wyoming, Montana, South Dakota, Minnesota, Wisconsin and southern Ontario.
Field Notes: The upperparts are dark brownish-black and the wings are dark, with two prominent white patches. In breeding plumage, the red-necked grebe has a black cap that extends below the eye, with a slight crest and a large, distinctive pale grey check patch that has whitish margins and extends upward to behind the eye. The front of the neck and the upper breast are deep chestnut, becoming paler on the belly, while the sides and flanks are greyish.

Willow Grouse
Population Estimate: 40M
Range / Habitat: Year-round in Arctic regions throughout the world.
Field Notes: Mottled brown and white in the summer, all white in the winter. Males with orange or red markings above the eyes. Rock Ptarmigan is slightly smaller, found at higher altitudes with less lush vegetation, has more grey tones in summer, and may have a black eye stripe in winter.
Personal Notes: The bottom photo was taken on a soggy, foggy day on the Pinnell Mountain Trail outside of Fairbanks, Alaska. Though I got a better photo at Denali, above, I left the bottom one in to show off the orange marking above the eye.

Mew Gull
Scientific Name: Larus Canus
Population Estimate: 2.5M - 3.7M
Range / Habitat: The common gull has a wide distribution, breeding throughout temperate and sub-Arctic parts of Eurasia. Two subspecies occur in Europe, the ‘nominate’ race L. c. canus is the subspecies occurring in Britain, extending through north-west Europe and reaching the White Sea in Russia. There is also a subspecies that occurs in North America. In Britain, this species breeds mainly in Scotland
Field Notes: It is generally similar in appearance to the herring gull (Larus argentatus) but is smaller, and has a smaller, thinner bill, a more rounded head and more active flight. The upperwings are pale grey in colour and have black tips featuring white spots known as ‘mirrors’. The white head develops grey streaks in winter and the legs and bill are greenish-yellow. Juveniles are greyish brown with brown upperparts.
Personal Notes:
Yellow-billed Loon
Population Estimate: 16-32K, Near Threatened
Range / Habitat: Breeds in Russia, Alaska and Canada primarily on inland freshwater lakes and ponds. Winters at sea mainly off the coasts of Norway and western Canada.
Field Notes: Typical loon shape and habits. Distinguishing feature is large, yellow, slightly upturned bill.
Personal Notes: A rare find in Fairbanks in a fairly small pond. This bird is not usually this far inland.

Sand Martin
Population Estimate: 50M
Range / Habitat: Summers in the northern US, Canada, Alaska. Winters in the tropics. Also common throughout Europe and Asia. Favors inland wetland areas.
Field Notes: Typical swallow / martin that is brown above and white below with a brown chest band. The Northern Rough-winged Swallow is similar but lacks the chest band.
Personal Notes: Also known as a Bank Swallow. This was a pleasant (but not uncommon) surprise find in Alaska among several Tree and Barn Swallows.

Black-billed Magpie
Scientific Name: Pica hudsonia
Population Estimate: 30M - 100M, including both Pica pica and Pica hudsonia
Range / Habitat: Year-round in a variety of habitats throughout the American West, northwest Canada and up into Alaska.
Field Notes: Large songbird with long tail. Shiny black head, tail, and back. White belly and wing patches. Deep blue on the wings as well.
Personal Notes: Striking, if common, bird of the American West. Some sources consider this bird the same species as Pica pica, which is found throughout Europe, much of Asia, and northwest Africa

Yellow-rumped Warbler
Scientific Name: Dendroica coronata
Population Estimate: 130M, Least Concern status
Range / Habitat: Summers in western US, most of Canada, and Alaska. Winters in southern US, Mexico and Central America. Preferred habitat is temperate forest.
Field Notes: Full-bodied black, white, and grey warbler. Characteristic yellow forehead, chin, armpits and rump (the latter seen only in flight). There are plenty of other similarly colored warblers but none with this particular distribution of yellow.
Personal Notes: This species has distinct regional morphs: the Myrtle (top) is predominantly Eastern U.S., while the Audobon's (bottom) is overwhelmingly Western
Barn Swallow
Scientific Name: Hirundo rustica
Population Estimate: 190M, Least Concern status
Range / Habitat: Most common swallow world wide, throughout the Americas, Europe, Asia, Africa, and into northern Australia. Breeding is in the Northern Hemisphere summer with winters in the Southern Hemisphere. Nests in barns and other man-made structures.
Field Notes: Iridescent blue on top, rufous chin, and light brown underneath with a long, forked tail. The Cliff Swallow can look similar but lacks the long forked tail, is generally white on the breast, and has a white forehead mark. Easily distinguished from other swallows in flight by its long forked tail.
Personal Notes: One of our best bird pictures to date!

Boreal Chickadee
Scientific Name: Parus Hudsonicus
Population Estimate: 8M
Range / Habitat: The boreal chickadee inhabits the northern coniferous forests of North America, breeding throughout Alaska, Canada and the northernmost states of the U.S.
Field Notes: A small songbird, the boreal chickadee (Parus hudsonica) is, as its name suggests, almost entirely restricted to the boreal forests of North America. The top of the head and the back of the neck often have a greyish tinge, which extends down the sides of the head to below the eye. A white stripe runs from the base of the bill to below the eye, while the chin and throat are black. The back, wings, rump and uppertail-coverts of the boreal chickadee are generally pale grey-brown, and the breast and abdomen are white.
