Pied Bush Chat
A
‘Passerine’ by ornithological classification, the Pied Bush Chats are small little
birds found in abundance around the Southern sub-continent. A Passerine, in
ornithological parlance, is a Song Bird, which is basically a Perching species.
These birds have the best control of their syrinx muscles among birds,
producing a wide range of songs and other vocalizations.
The males
are black with white shoulders and vent patches whose extent varies among
populations. Females are predominantly brownish while juveniles are speckled.
Another
unique feature of Passerines is their feet. The foot of a passerine has three
toes directed forward and one toe directed backwards. Their leg muscles are
specially adapted to hold on to perches in a vice like grip, and tighten around
their perches in an involuntary motion, at the slightest sign of imbalance of
the perch. This helps the bird to fall asleep in a perched position – a rarity
amongst birds.
Passerines also make use of that backwards
facing toe in another fashion. During fights for territory, sometimes they end
up wrestling and use their feet to grab onto the other bird and even hold their
beaks shut! Probably, the only reason eagles and falcons aren’t considered passerines
are because they don’t sing.
Males sing aloud during the mating season and
build nests in holes found in rocks, caves or trees. Large colonies of these
birds can be found in the fields, bordering jungles in the country.
