In Barn Swallow
, males mimic grown nestlings by emitting enticement calls, which resemble intense nestling food-begging calls, to "trap" the parental behavior of potential mates (i.
For example, the sole ectoparasite observed associated with barn swallow

Also, the fact that certain avian species, such as Eurasian Blackbirds, Great Gray Owls, and Barn Swallows
in Austria, are especially vulnerable to USUV infection, is reminiscent of the observation that WNV in North America has primarily affected American Crows and Blue Jays (19,20).
Testosterone, plumage coloration and extra-pair paternity in male North American Barn Swallows
Scientists found female barn swallows
will not hesitate to cheat on their partners if they spy a more handsome suitor.
Furthermore, the reproductive behavior and ecology of the barn swallow
differs from that of the cliff swallow (Samuel 1971; Ramstack et al.
Breast plumage varies among male barn swallows

Buchanan 1958) and occasionally barn swallows
, Hirundo rustica (cf.
We studied three passerines nesting in Norman, Oklahoma, USA; House Sparrows (Passer domesticus) and Eastern Bluebirds (Sialia sialis) nested in monitored boxes while Barn Swallows
(Hirundo rustica) nested near the nestbox population.
(Hirundo rustica) increased in density in 2008 but only in the moderate-impact area.
The bird - a barn swallow
- will fly 8,000 miles to Argentina for the winter; the monarch butterfly will glide to the mountains of Central Mexico, while the American eel-one of the few fish that spawns in the ocean but lives in freshwater estuaries - will swim down a creek and travel 1,500 miles to the Sargasso Sea in the middle of the Atlantic Ocean.
Sexually-selected infanticide by Barn Swallow
males to gain access to a female has been observed (Crook and Shields 1985; Moller 1988, 2004).
