BARN SWALLOW (Hirundo rustica)
is the most widespread species ofswallow in the world. It is a distinctive passerine bird with blue
upperparts, a long, deeply forked tail and
curved, pointed wings. It
is found in Europe, Asia, Africa and the Americas. In Anglophone Europe it is just
called theSwallow; in Northern
Europe it is the only common species called a "swallow" rather than a
"martin".
The adult male Barn Swallow of the nominate
subspecies H. r. rustica is 17–19 cm (6.7–7.5 in)
long including 2–7 cm (0.79–2.8 in) of elongated outer tail feathers.
It has a wingspan of 32–34.5 cm (12.6–13.58 in) and weighs
16–22 g (0.56–0.78 oz).
The song of the Barn Swallow is a cheerful
warble, often ending with su-seer with the second note higher than the
first but falling in pitch. Calls include witt or witt-witt and a loud splee-plink when excited (or trying to chase
intruders away from the nest).
The Barn Swallow is similar in its habits to
other aerial insectivores,
including other swallow species and the unrelated swifts.
Lays two to seven eggs, but typically four or
five.[INFO:WIKIPEDIA]
