Bull tule elk at Pt. Reyes National Seashore

A bull tule elk at Pt. Reyes National Seashore. Bulls enter the rut (breeding season) in late July and it continues until September. During the rut, bulls bugle, roll in wallows, thrash the ground with their antlers and mark their territory. One master bull assumes command. Other primary and secondary bulls are responsible for 80% of the breeding. Bulls may have harems up to 60 cows. Calves are born in April and May after a gestation period of 8 months.
