    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 TheAuk:Ornithological Adrances,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 enering the world.

This educational method was first observed in 2012 by Sonia Kieindorfer,a biologist at Flinders University in South Australia,and her collcagues.Femake 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—asound 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.Firstthey collected sound datd from 67 nests in four sites in Queenslang before and after hatching,Then they identified begging calls by analyzing the order and numberof 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. In addition,the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.

This observation hints that effective embryonic learning could signal neurological(神经系统的)strengths of children toparents.An evolutionary inference can then be drawn.”As a parent,do you investin quality children,or do you invest in children that are in need?”Kleindorfer asks.”Our results suggest that they might be going for quality.”
