Cornell Lab Staff Member Visits Snowy Owls with Denver Holt. July 22, 2014
Cornell Lab staff writer Pat Leonard travelled to Barrow, Alaska, to visit owl researcher Denver Holt of the Owl Research Institute, who has been studying Snowy Owls for more than 20 years. They visited the owl nest that’s featured on the explore.org and Bird Cams site. The nest originally had seven owlets, but the researchers know of only two that are still alive. Pat Leonard describes how the nest checkup went in her blog.
