I just read a little article in a really great newsletter called The Whippet. A study on bats found that female bats stayed in the warmer valleys and the male bats tended to go to the higher, cooler mountain areas. And that across the board, in both birds and mammals, females feel colder. Their core temperatures are actually not any colder, but they feel colder, and the researchers think it's an evolutionary adaptation to making sure their offspring stay warm. If the mother feels cold, she will tend to stay in warmer places, and very young animals are not very good at staying warm.
