Almost all domestic and wild goat breeds have beards, though male goats (bucks) nearly always grow larger, thicker, and more prominent beards than females (does) because of higher testosterone levels.

Antlerless Bull Elk at the Zoo
The bull (male) elk are beginning to drop their antlers—a yearly occurrence that happens a few months after breeding season due to a decrease in testosterone.
Antlers drop annually in late winter, typically January through March. The dropped antlers are called “sheds,” and the process does not hurt the buck. From spring to summer, the antlers regrow and are usually larger than the previous year.
Here is one at the North Carolina Zoo.
