Just like humans, birds too rely on sound to communicate.However, they do not have a "language" in
the true sense of the word and instead produce a variety of sounds to convey different emotions.
Often, birds recognize their mates (or young) by sound rather than sight.Hungry young birds use
begging calls to let their mothers know it is feeding time.Alarm calls, flight calls and warning calls are other sounds made frequently by adults.
A new study shows that songbirds rehearse (排演) their songs even in their sleep.The activity in the
brain of the birds when asleep is similar to the brain activity when the birds were awake and singing.The
team used tiny recording devices to measure the activity of individual brain cells in four songbirds both
when they were singing and when they were asleep.
Apparently the bird stores a song after hearing it, and then rehearses it later in its sleep.Scientists now
believe the birds "dream of songs and tunes" to help them master the fine art of singing and that sleep
plays a key role in the learning process!
Many songbirds learn to sing listening to adult birds of the same species.However, if separated from
the adults, the young birds develop sounds which are hard to understand instead of normal song patterns.
Researchers carried out an experiment in which a male bullfinch (灰雀) was raised by a female canary
(金丝雀). The bullfinch soon learned the canary"s song and when it was later mated to a female bullfinch, Mr.Bullfinch taught his children the canary"s songs.
Last year, a British survey of London"s songbirds showed that the city"s birds are losing their tunes.
Birds could hardly hear one another, over the traffic noise;as a result, instead of copying the sweet
notes of the adults, young birds were copying the sounds they heard most often, namely car horns and
beeping cellphones!
