	Birds in Seymour township, southeast Ontario: chipping sparrow and American tree sparrow
		The American tree sparrow is somewhat larger, a chunky sparrow with a distinct fl mark on a pale breast, a brown cap, and brown and grey in place of the fl and white facial pattern of the smaller "chippy".
		The American tree sparrow (orange on chart) is sometimes called the "winter chippy" because of its broadly similar appearance and strong association with winter cold spells in southern Ontario.
		The chipping sparrow is a common migrant and summer resident at Presqu'ile provincial park, roughly 40 km to the south, with an extreme early sighting on 06 April, a late date of 11 November, and one reported winter sighting in early January (LaForest, 1993, pp.346-347).

	Canada Bunting (Tree Sparrow.)
		Twenty or more, perched on the same tree, often delighted me with their choruses, now and then varied with the still clearer notes of one or two White-throated Finches, that, like leaders of an orchestra, seemed to mark time for the woodland choristers.
		Their flight is more elegant and elevated than that of most of our Sparrows, and they pass through the air in rapid undulations, more regular and continued than those of any other bird of the family, except the Fox-coloured Sparrow.
		Many of the Tree Sparrows breed in New Brunswick, in Nova Scotia, and, I have reasons for believing, in the northern portions of the State of Maine.

	Utah Division of Wildlife Resources
		The American tree sparrow, Spizella arborea, is migratory, breeding in Alaska and northern Canada, and wintering in southern Canada and the northern United States south to northern Texas.
		The breeding habitat of this species is open scrubby areas, such as open tundra with scattered shrubs, and areas near treeline; during migration and on its wintering grounds, the American tree sparrow utilizes fields, marshes, and residential neighborhoods.
		In winter, when seeds on the ground are hidden by snow, American tree sparrows have been known to hover over weeds, beat them with their wings to dislodge seeds, and then to fly to the surface of the snow to find and consume the seeds.

	All About Birds
		The American Tree Sparrow is a common winter visitor in backyards all across southern Canada and the northern United States.
		As in most birds, the American Tree Sparrow is sensitive to changes in day length, which influence the growth of the sex organs.
		If the area is about 10-20% filled by tree sparrows, and they have 1-ha territories, as is the case near Churchill, Manitoba where they have been well studied, then approximately 10 to 20 million pairs should be breeding.

	TEXBIRDS Archives -- December 2000 (#527)
		We found the sparrow in the wet, weedy ditch/hedgerow on the west side of the gravel lane, near the highway with a small flock of sparrows - one Harris' Sparrow and several other Spizellas which we didn't see well enough to identify with certainty.
		We returned about mid-day and found no sparrows in the hedgerow other than the everpresent Savannahs and a few Vespers, both of which are foraging in the fields on either side of the gravel lane.
		In addition to the Tree Sparrow, we were able to find large flocks (1000 - 2000 birds) of Lapland Longspurs in the same area I reported finding them yesterday, along with smaller numbers (200-500) of McCown's Longspurs in the same location.

		In the southeast, Chipping Sparrows are common in open pine forests; in the northern and mountain states, they can be found in openings in the forest, along streams and lakes, in spruce bogs mountain meadows and in stands of jack or red pine.
		The song of the Chipping Sparrow is a simple, dry trill, all on one pitch, so similar to that of both the Pine Warbler and Dark-eyed Junco that even the experienced observer can be fooled.
		The Chipping Sparrow is distinguished in adult plumage by its distinctive head pattern: rusty cap, white forehead bordered by fl; white superciliary stripe; fl ocular stripe, and gray rump.

		Outside of the nesting season, Tree Sparrows are usually found foraging in flocks in low bushes or on the ground.
		American Tree Sparrows are complete migrants, meaning there is no overlap between breeding and wintering range.
		Most of the American Tree Sparrow’s nesting area is remote from human disturbance and well protected, although large-scale development in the far north may threaten this species.

		Both Tree Sparrows and Chipping Sparrows have a brown back, and white breast but in the winter, only the Tree Sparrow has the rusty cap.
		Although the Tree Sparrow has a spot on the breast, it is not always visible and the absence of a spot is not reliable for identification purposes.
