Allen Vinson caught a pair of Red-tailed Hawks mating. Yes, an x-rated sighting for you today. In the first photo the male is approaching the female. In the second photo, they are mating. And in the last photo the male flies off.
Red-tailed Hawks are year round residents of the Mendonoma Coast. Here's a photo of one hunting, taken by Linda Morley-Wells.
Thanks to Allen and Linda for allowing me to share their photos with you here.
