摘要
DEAR EDITOR,Recent studies have shown that the closely related cinereous tit(Parus cinereus)and green-backed tit(P.monticolus)in China display strong egg recognition ability in contrast to tit species in Europe,which lack such ability.However,egg recognition in other populations of cinereous and greenbacked tits and additional Paridae species still requires further research.
