满园彩票hy do birds sing?
满园彩票满园彩票ird songs are common sounds to us all, but why do birds sing? 满园彩票magine you're a male willow warbler, and you’ve just flown 2,400 miles (4000 km) from 满园彩票frica. 满园彩票t's spring, and you need to find a mate quickly. 满园彩票owever, your home is a woodland and you’re the colour of leaves. 满园彩票hat better way of advertising to a passing female that you are here and would make a fine father for her chicks than by having a clear, loud and recognisable song?
