	Birds, Familiar: Tree Swallow, Life Histories of North American Birds, A.C. Bent
		The tree swallow commonly nests in isolated pairs, showing none of the strictly communal habits of the purple martin and the cliff swallow, but the birds are frequently found nesting in groups, their nests scattered about, not far apart, in favorable feeding localities.
		In the air the tree swallow resembles somewhat the purple martin, the similarity being due probably to the triangular shape of the wing in both birds--a triangle with a sharp apex and a fairly broad base.
		The bank swallow is readily distinguished from the tree swallow by its habit of hugging its wings close to the side of its body when it sails and by the suggestion of soft fluttering in the motion of its wings.

	Coveside Swallow Houses
		The slender Tree Swallow is wonderful at aerial stunts, swooping and diving to catch flying insects. Their reputation for catching mosquitoes far exceeds reality, as they generally retire about the time of day when mosquitoes are abundant.
		Tree Swallows like playing with feathers, and can frequently be seen tossing one into the air and catching it, or chasing another swallow with a feather.
		Tree Swallows will tolerate fairly close neighbors of their own kind. Nesting boxes may be placed as close as 30 feet apart, or even on the same tree. They should be mounted on posts or trees out in the open, near water. It is even acceptable to place the post in water.

	Tree Swallow (Tachycineta bicolor)
		Tree Swallows are behaviorally monogamous (Leffelaar and Robertson 1986).
		Swallows are fairly tolerant of human interference, however predators are often introduced and breeding patch size is constricted.
		STATUS: Tree swallows are under no special threat, but their extirpation from areas of southern California and the removal of snags of appropriate size from riparian areas throughout the West indicate a necessity for continuing research.

	Swallow Houses
		Nesting is quite synchronous in Tree Swallows; that is, females tend to begin nesting within a week or 10 days, usually in April, of their neighbors.
		Tree Swallow houses should be placed 5 to 15 feet high on a post or tree in open areas.
		In the northern portion of their range, pair formation begins in mid-April and breeding begins in late May. In the southern portion, breeding begins in early May. Violet-green Swallow houses should be placed 9 to 15 feet high in open or broken deciduous or mixed deciduous-coniferous forests, wooded canyons, or edges of dense forests.

	Birds of Nova Scotia - Tree Swallow (Site not responding. Last check: 2007-11-05)
		Tree Swallows are the first swallows to arrive in spring (average 6 April, earliest 22 March), but a dying bird in Halifax on 3 March 1968 and two lively ones at Cape Sable on 28 February 1976 clearly were not normal migrants.
		This is unquestionably a boon to the swallows, but these boxes are also coveted by House Sparrows, and competition is often very keen, with the ruffians usually taking over.
		It is always pleasing to have the swallows come back in early spring, but an early arrival does not always work well for the swallows, as happened in April 1940.
