Coalition
August 20, 2016 - Busanga Plains in Kafue National Park, Zambia
When male lions work together, they form a coalition. These two fellas where a part of the same pride as the lioness (aka The Killing Machine) and her cubs.
When members of a coalition first meet up they rub heads together.
This is called "flehmening" which is what some animals do when they investigate a smell of interest. They can detect pheromones and sexual readiness of potential mates.
The Lion King.
I love this shot.
