　　Red-backed fairy wrens(鹪鹩),which live in northern and eastern Australia,

lay three or four eggs at a time.

　　Before birth, babies can tell the difference between loud sounds and voices.

They can even distinguish their mother's voice from that of a female stranger. But When it comes to embryonic learning(胎教), birds could rule the roost. As recently reported in The Auk:Ornithological Advances, some mother birds may teach their young to sing even before they hatch(孵化). New-born chicks can then imitate their mom's call within a few days of entering the world.

　　This educational method was first observed in 2012 by Sonia Kleindorfer, a biologist at Flinders University in South Australia, and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When the eggs were hatched,the baby birds made the similar chirp to their mothers-a sound that served as their regular"feed me!"call.

　　To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.

It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs, the more similar were the babies' begging calls.
