Are there swallows in arizona
It is recognized by a pale, orange-brown rump, white forehead, dark, rust-colored throat, and steel-blue crown and back. The cave swallow is similar in appearance, but has a rust-colored forehead and pale throat; it is restricted to southeast New Mexico and central, south, and west Texas.
Barn swallows have steel-blue plumage on the crown, wings, back, and tail. The forehead, throat, breast, and abdomen are rust colored. Females are usually duller colored than the males. Cliff and barn swallows are found throughout most of North America. Breeding occurs northward to Alaska and the Yukon, across Canada, throughout the western United States, and south into Mexico. Barn swallows are common nesters in most of the southern United States, except Florida.
Until recently, cliff swallows did not breed in the southern United States east of central Texas and south of west-central Tennessee or western Kentucky.
Reports of new colonies in eastern Tennessee, Louisiana, Alabama, Arkansas, Mississippi, and Florida suggest a range expansion into the southern Atlantic seaboard and Gulf Coast states.
Barn swallows are also found in Europe, North Africa, and Asia. Barn and cliff swallows regularly build mud nests attached to buildings and other structures, a habit that sometimes puts them into conflict with humans. This is particularly true of the cliff swallow, which nests in large colonies of up to several hundred pairs.
During the breeding season, it lives in colonies that may have hundreds to thousands of pouch-shaped mud nests attached to stony surfaces. Before the 20th century, the bird spent its breeding season primarily in the rocky foothills of the mountains of the West, typically nesting beneath the ledges of cliffs and canyon walls. During our expansive 20th century, it extended its breeding season range dramatically, both northward and eastward, capitalizing on nesting sites offered by newly constructed bridges and buildings.
Its fall and spring migrations each last for several months. It favors locations near streams, lakes or ponds, particularly if there is a source of mud for use in nest building. It normally avoids open desert basins and dense forests that lie beyond reasonable access to water and mud.
It may set up housekeeping at elevations ranging from near sea level to some feet. The Cliff Swallow's preferred nesting sites - in the foothills of the mountain ranges of the West - includes cliff faces and canyon walls in drainages, hills, escarpments and rock outcroppings. Its preferred sites - in its more recently adopted, expanded habitats - include vertical concrete surfaces beneath horizontal structural ledges of highway bridges and culverts and buildings.
During the non-breeding season, it may be nomadic, moving and searching continually for insect concentrations. Its migratory routes take it across a wide diversity of landscapes, sometimes moving with flocks of thousands. Prior to and during nesting, the Cliff Swallow typically forages as part of a flock, which facilitates discovery of insect prey concentrations.
With the approach of mating, the cantankerous Cliff Swallow may fight for a nest site, especially in the more central and protected parts of a colony. They can also swoop in and ruin your backyard BBQ, taking food right off the plates of your guests. This can result in rather unclean and unsanitary places for humans since their feces can carry parasites and diseases. We understand birds, their nesting habits, and which ones are protected, so we can successfully treat your home or business for these pests.

Jeter remarks that in the colony of swainsoni he watched along the upper San Pedro River, all birds were easily classified as either dark- or white-fronted, there were no intermediate colors, and he identified only one apparent mixed pair among six nests that he watched. Phillips et al point out that northern birds continue to migrate through Arizona until June and question whether the white-fronted birds Jeter saw were local breeders or just migrants headed farther north.
All require further testing in the field. The southwestern subspecies of Cliff Swallow P. Dark foreheads are sometimes seen on other Cliff Swallows, but apparently only a small minority of individuals, and only within miles or so of the range of swainsoni. These birds deserve more study. What is the true range and status of swainsoni in Arizona?
How many colonies? Do they really arrive in spring weeks later than other Cliff Swallows? Do white-fronted birds mix with dark-fronted swainsoni in these Arizona colonies? What is the distribution and frequency of truly dark-fronted birds outside of the limited range of swainsoni? Do all swainsoni have pale lores? Are there any differences in voice, nest structure, etc? Brown, Charles R. Poole, Ed. Browning, M. Western Birds Jeter, H. Cliff Swallows of mixed plumage types in a colony in southeastern Arizona.

As for Cave Swallows, I did not look too carefully at our series with regard to your questions just now, but it may be of note to you that most all? David, As Dan mentions, we do have dark-fronted Cliffs here in Louisiana. These birds nest in SW LA and are found mixed in with the more abundant typical pale-fronted birds. As Dan pointed out, Dittmann and Cardiff can probably tell you much more…. Just read this. I believe I reiterated it again this year on my web site.
They arrive early april and as of last weekend were starting to nest build. Some are done and gone, these tend be the ones like the one in the back of my pic I sent you.
