Tweet of the Day - Chowchilla
Michael Palin presents the secretive chowchilla from Queensland, Australia. The chowchilla gets its name from its song, which is one of the most distinctive sounds of the coastal rainforest of north-east Queensland. You're not likely to see the bird though because it spends its time skulking on the forest floor. Chowchillas belong to the family known as logrunners because they feed and nest on or near ground-level. They're stout thrush-like birds; the males are dark brown with a white chest and throat, whilst the female's throat is rusty-orange.
Chowchillas have been found to sing with different dialects in different areas. Within say, 50 hectares, all the family groups of pairs and non-breeding younger birds may share the same dialect. But in an adjacent area, the families may assemble some of their song components slightly differently. Over time, their song culture could change and a new dialect would be born.
