The female black-tailed deer have five scent glands on their bodies and the males have six. Each one is on a distinct spot on the deer’s body and can transmit different kinds of pheromonal information from one individual to another, or from one individual to the entire herd.
The one gland specific to the males is the one on the forehead between the antlers. It secretes a scent that communicates the buck's physical maturity and whether or not it is old enough to breed.
You’ll often see the bucks rubbing their foreheads against trees and other vegetation, marking them with scented advertisements to females and other males in the area.

There’s a buffet of anchovies off the Orange County coast — and the humpback whales are here to feast.
It’s not just a good place to find a meal during their annual migration down to the warm waters of Mexico, but also an opportune chance to turn the ocean into a classroom, teaching newborn whales the basics of how to feed. And the footage captured recently of the small calves attempting to scoop fish into their mouths — sometimes missing — couldn’t be any cuter.
