For Next Christmas…

In most deer species, only the male grows antlers, but that’s not true for most reindeer. Although the females in certain populations do not have antlers, many do. During certain times of year, you can still tell the sex of a reindeer by checking for antlers. That’s because males lose their antlers in winter or spring, but females shed theirs in the summer. The females are much smaller than the males, but you may get thrown if you come across a particularly large female or a small male.
Because reindeer shed their antlers at different points of the year based on their sex and age, we know that Santa’s reindeer probably aren’t older males, because older male reindeer lose their antlers in December and Christmas reindeer are always depicted with their antlers. That means Santa’s sled either has to be pulled by young reindeer, constantly replaced as they start to age, or Santa’s reindeer are female. Do you want to imagine a rotating crop of sleigh pullers or an all-female lineup? It’s up to you.
