As recently reported in TheAuk：OrnithologicalAdvances，birds may teach their young to sing even before they hatch (孵化). chicks can then imitate their mum\\’s call within a few days of entering the This educational method was first observed in 2012 by Sonia biologist at Flinders University in South Australia，and her 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 they collected sound data from 67 nests in four sites in Queensland

It turns out that baby red-backed fairy wrens also emerge chirping like their mums. 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 mum\\’s voice were rewarded with the most food. some mother

problem，new approaches While clean energy is increasingly used in our daily life，global warming will continue for some decades after CO2 emissions (排放) peak. So even if emissions were to begin to decrease today，we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation. When it comes to adaptation，it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard，but to a constantly shifting set of conditions. This is why, in part at least，the US National Climate Assessment says that：“Thereisno‘one-sizefitsall’adaptation.” Nevertheless，there are some actions that offer much and carry little risk or cost. Around the world, people are adapting in surprising ways，especially in some poor countries. Floods have become
