Santa's Little Helpers
The female of the species often has to struggle hard for recognition as the fight for equal pay demonstrates only too well.
Santa's reindeer are another good example because while the male of the species lose their antlers at the end of the mating season in early December, female reindeer keep their antlers throughout the winter months.
Which means that Dasher, Dancer, Prancer, Vixen and so on must all be female, as well as Rudolph, the red-nosed one!
