Impala Wrestling Video
Why do Impalas Fight?
Male impalas usually engage in a fight for two reasons: for courtship (during the breeding season; called rutting), or for fun.
In the video example the young bachelors are just playing and testing their skills against one another. Their casual fight sessions are also great training for when they become older.
Once they reach 4 to 6 years old male impalas attain enough strength and stature to hold a territory. They are then ready to seek a harem of females.
