Northern Canada

n ongoing surge of extralimital species across the North continues to fascinate and trouble northern birders.Reports of Magnolia Warbler, Ovenbird, Red-eyed Vireo, and Western Tanager added to the ever-growing list of Neotropical migrants appearing well beyond their ranges in the northwest.Two firsts for Nunavut this season were Piping Plover and Turkey Vulture, while Yukoners saw their first American White Pelicans.Two southern invaders bred for the first time in the Yukon this summer; an influx of American Crows in Watson Lake, Teslin, and Whitehorse culminated in the territory's first confirmed breeding record for this northward-expanding cotrid.While the crows were greeted with only modest interest, the territory's first nesting House Sparrows inspired even less excitement.The Yukon's summer weather was warmer than average; glacial melt, heavy winter snow pack, and rain made for record flooding in the Yukon Southern Lakes.In the Fort Simpson region of Northwest Territories, June was dry for much of the month but saw heavy rainfall during the latter days of June.The Arctic regions were again increasingly warmer than usual this summer.On 21 June 2007, 15-year-old Yukoner Malkolm Boothroyd and his parents cycled southward to begin a year-long, fossil-fuel-free journey in search of birds.It's an inspiration to see a great birding adventure launched to raise awareness of bird conservation and climate change ( ).WATERFOWL THROU6H SHOREBIRDS A nesting Snow Goose at St. Patrick Bay on the n.end of Ellesmere I., Nunavut 1 Jul enjoyed an absolutely awe-inspiring view: perched adjacent a Gyrfalcon nest on the tip of a 270-m rocky spire overlooking the Nares Strait to the icecaps of Greenland (ph.DS).Brant are regular late May-early Jun migrants at Akimiski L, Nunavut; this year, daily totals were in the 2000-3000 range until 1 Jun, when there was a major departure on the full moon.Smaller numbers (<500 per day) lingered until 10 Jun.A later movement of birds presumed to be from s. James Bay staging areas was noted 6 Jun, when small flocks were seen crossing Akimiski I. from the s. on a northeasterly path and continuing over the James Bay ice pack (KA et al.).A few late Brant were seen at Nares L., s.Yukon 6 Jun (CE, HG).A late but noteworthy spring report was of a Barnade Goose in the company of Canada Geese and possibly paired with one at Akimiski I., Nunavut 26-28 May (KA et al.).A pair of Trumpeter Swans mark the southernmost breeding location for this species in James Bay.A casual stop to check a group of seemingly out-of-place swans at Nares L., s.Yukon 6 Jun yielded the Yukon's first American White Pelicans (DP); a quick call to other birders ensured that the 4 pelicans were photographically documented (ph.CE, HG).In response to subsequent media coverage of the pelicans, it was learned that they had been seen at nearby Tagish for about a week (ph.LG).An aerial survey of islands in Akimiski Strait, Nunavut 5 Jun found 60 ad.Double-crested Cormorants and 30 nests (KA et al.).A Turkey Vulture, Nunavut's first, was an unexpected find in Arviat 23 Jul (ph.LR, MP).An imm.Bald Eagle at Herschel I., n.Yukon 20 Jun (ph.CE, DA, PF, LJM) established just the 2nd record for the island.The connection between the northern and the southern hemisphere's bird populations was beautifully demonstrated this year by the in-A Snow Goose on its nest at St. Patrick Bay, Nunavut on the north end of Ellesmere Island 1 July 2007 overlooks a true Arctic wilderness.Photograph by Doug Stem.was again noted nesting this year in Tombstone Park, cen.Yukon 28 Jun; 4 Tundra Swans were seen on the same day at Chapman L., just n. of Tombstone Park (BM et al.).Three Redheads (2 males, one female), n. of their normal range, were seen on the Mackenzie R., NWT 18 Jun (ph.AL).Heavy snow delayed the return and subsequent nesting chronology of Common Eiders and other species on Southampton I., Nunavut this year (MM).Eiders were also delayed by up to two weeks at High Arctic locations, primarily due to heavy ice conditions along the migration route as opposed to breeding sites (MM).A male Hooded Merganser, very rare in cen.Yukon, was seen near Dawson 26 Jun (LD, KR).A noteworthy summer concentration of 77 Ruddy Ducks was recorded at the Whitehorse sewage ponds, s.Yukon 27 Jul (BD, HG).A female White-tailed Ptarmigan with a brood of at least 5 chicks was seen on Keno Hill, cen.Yukon 6 Jul (ph.MOD).A pair of Pacific Loons observed on Akimiski I., Nunavut 10 Jun (KA et al.) may tercontinental migration of marked Peregrine Falcons.The Falcon Research Group put satellite transmitters on 7 falcons in Chile in Feb 2007; on 21 Jun, the ad.male known as "Seven" arrived n. of the Arctic Circle in Tuktut Nogait N.P., near Paulatuk, NWT.Two other marked birds, named "Linda" and This trio of Redheads on the Mackenzie River, Northwest Territories 18 June 2007 were north of the species'typical breeding range; however, they may be post-or non-breeders.Photograph byAnthony Levesque."Sparrow King," traveled to the Wager Bay and s.Baffin I. areas of Nunavut, respectively, to spend the summer months.Two ad.Whooping Cranes seen 28 Jun at Loche L., Tulita District, NWT (RO) were sev-600 NORTH AMERICAN BIRDS Northern Canada
