Witnessing red-tailed hawks mating in the wild is a rare and exhilarating experience for any nature enthusiast. On a crisp morning with perfect light and a gentle breeze, I ventured out hoping to spot short-eared owls but stumbled upon something even more remarkable: a pair of red-tailed hawks at an old nest site in Box Elder County, Utah. Movement in the nest and fresh nesting material signaled activity, drawing me closer.
What unfolded next was unexpected—a swift mating session on a lichen-covered rocky outcropping near the nest. These powerful raptors, known for their aerial prowess, displayed intricate behaviors during this brief but intense ritual. For bird lovers interested in aggressive wild bird behavior, such observations highlight the dynamic world of raptor interactions.
Discovering the Nest Activity
The female red-tailed hawk was the first to catch my eye as she left the nest, revealing new branches and materials indicating breeding preparations. Box Elder County’s rugged terrain provides ideal nesting spots for these adaptable birds, which often reuse sites year after year. This pair’s presence suggested they were in prime mating season, typically early spring when days lengthen and food is abundant.

Soon after repositioning for better light, the male flew in, landing nearby. His approach showcased the fine barring on his tail feathers, a subtle sexual dimorphism distinguishing him from the female, whose tail lacks such detail but shares a thick terminal band.
The Male’s Approach and Mounting
The male red-tailed hawk glided toward the receptive female, who adopted a crouched posture on the stable rock surface. This positioning minimizes injury during copulation, a common adaptation in birds of prey. Both hawks maintained balance effortlessly, with the female’s body language signaling readiness.

As he neared, the alignment of their forms created an illusion of a single bird, emphasizing their synchronized movements. The female’s tail fanned slightly, preparing for the cloacal contact essential for internal fertilization in raptors.

The Intense Mating Sequence
Mounting occurred swiftly, with the male gripping the female’s back using curled talons to avoid harm—a protective behavior observed in many raptor species. She remained crouched, supporting his weight as he positioned above her. This phase lasted mere seconds, typical for red-tailed hawks where copulation reinforces pair bonds multiple times daily during breeding.

Throughout, the male emitted unique calls differing from his standard screech, possibly signaling completion or arousal. Though I couldn’t record it, such vocalizations are rarely documented but aid in territory defense and pair communication.

The female cleverly dropped her left wing to the rock, stabilizing them both amid the vigorous activity. Their tails aligned precisely—his above hers initially, then shifting—facilitating the transfer. Tail positions and wing adjustments are key to balance on uneven perches like this lichen-covered outcrop.

The male varied wing positions, spreading them slightly for stability, talons always fisted safely. By 30 seconds, fatigue seemed evident, longer than previous observations on less stable perches like junipers.

Dismount and Post-Mating
The male began dismounting around the 34-second mark, the female raising her tail skyward—a post-copulatory signal. They separated calmly, the session complete in this wild display.
