Here is something appropriate for the season. Both male and
female reindeer grow antlers, and despite the depiction of
Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen,
and Rudolph as males in media; they are most likely females.
Most male reindeer lose their horns in the winter when Christmas
occurs. Females lose their antlers during the warm summer
months. Males are much less nourished and fattened than the
females at this time of year. Santa’s reindeer must be big and
strong enough to pull a sleigh full of toys and would need to be
in peak physical condition. Hmmm!
