Right now, partially or fully exposed to the sub-zero temperatures we’re experiencing, female Black Bears are giving birth to cubs that are blind, nearly hairless and weigh less than a pound. Although the mother’s metabolism is slightly reduced, her body temperature is relatively high, and she is very responsive to her cubs. The cubs do not hibernate – they retain full metabolism in order to maintain maximum growth, nursing frequently and for long periods of time. Their mother keeps them warm by hovering over them and breathing on them. Like human mothers, she sleeps when her cubs sleep, but awakens quickly and responds to their cries. (Photo taken during research; cub is roughly two months old.)
