Birds in the wild appear to lower their bill temperature to prevent heat loss in order to preserve energy when food is scarce, according to new research.

The study, led by a team of researchers at the University of Glasgow and published in the Journal of Experimental Biology, used thermal imaging technology to measure the body surface temperature of the small songbird, the Great Tit, when faced with temporary food shortage.

The measurements showed that shortly after food became unavailable, the birds allowed their bill to cool. MORE
