About Swallow Birds Swallows feed on insects and spend a large part of each day in the air catching flies, beetles, and mosquitoes. Amber-list species are those with an unfavorable conservation status in Europe; those whose population or range has declined moderately in recent years; those whose population has declined historically but made a substantial recent recovery; rare breeders; and those with internationally important or localized populations.

Individual species may be selective, they do not scoop up every insect around them, but instead select larger prey items than would be expected by random sampling. In addition the ease of capture of different insect types affects their rate of predation by swallows. They also avoid certain prey types; in particular stinging insects such as bees and wasps are generally avoided.

Swallows feed on insects, these acrobatic birds catches their prey as they maneuver through the air. The Northern Rough-winged Swallow is seen throughout the USA and all of the southern provinces of Canada.

Know which spots swallows like to build their nests in. They also prefer surfaces such as wood, concrete, or masonry.

Both barn and cliff swallows travel impressive distances each year. It’s thought that they originated in Africa, where a drier climate may have promoted making nests from mud—a behavior also seen in flamingos, for example.

Swallows are indeed harbingers of spring and are among the first arriving migrants in California. It appeared and disappeared along large rivers in the Congo Basin.

If swallows chose your structure to nest on the previous year, there is a good chance they may return. The chest and parts of the underside of the wings are white, cream or pinkish.

One of the few times you will ever see Barn Swallows on the ground is when they are filling their faces with mud.

In Barn Swallows the tail of the male is 18% longer than the females, and females will select mates on the basis of tail length. The tail has 12 feathers and may be deeply forked, somewhat indented, or square-ended.

They like the same size nesting box, so placing two houses near each other, or even back-to-back on a post, will encourage Tree Swallows to occupy one and bluebirds the other. Unfortunately, this sometimes leaves the young too long without food, and they perish.

Cave swallows lay three to five speckled eggs and rear two or three broods. It lays four to six white eggs and rears one, or possibly two, broods per season.

Barn swallows nesting singly or in small groups on a structure can cause similar problems but of a lesser magnitude due to the smaller numbers present. Please note that this product is not reccommended as a substitute for the flasher, but only as an enhancer.

Look for a squared off tail (barn swallows have forked tails) and a pale yellow rump (purple martins have a solid colored back). Catharines, Scarborough, Shelburne, Thornhill, Toronto-Central West, Toronto-Central East, Toronto-Etobicoke, Toronto North York, Vaughan, Welland, Whitby, Woodbridge.

At large colonies, swallows may arrive in successive waves. Under suitable conditions, a nest is quite durable and may be used in successive years.

Although a few may nest in the same area, they do not nest close to each other like some other Swallows or Swifts. Also lacks the tail streamers, but not diagnostic because the Barn may lose its tail streamers during a moult.
