Sexing Reindeer

I don't know who wrote this, or if the rights are reserved, but:

"According to the Alaska Department of Fish and Game, while both male and
female reindeer grow antlers in the summer each year (the only members of the
deer family, Cervidae, to have females do so), male reindeer drop their
antlers at the beginning of winter, usually late November to mid December.
Female reindeer retain their antlers till after they give birth in the
spring. Therefore, according to every historical rendition depicting Santa's
reindeer, every single one of them, from Rudolf to Blitzen........had to be a
girl. We should've known. Only women would be able to drag a fatman in a red
velvet suit all around the world in one night, and not get lost!"
