"In Sturt National Park, near Tibooburra in central Australia where
temperatures can range from freezing to nearly 50°C, there lives a small bird
with a white back, forked tail and – as we’ve just discovered – a very clever
strategy to survive its extreme environment.
The white-backed swallow (
Cheramoeca leucosterna) is a type of passerine –
the largest group of birds, comprising 60% of all bird species.
Scientists have long thought these birds incapable of deep torpor – a
controlled state of reduced body temperature that saves energy and has been
found in many animals in the northern hemisphere, where winters are more
severe.
But our new paper, published today in the journal
Current Biology, shows
otherwise."
