Dr. Brian Linkhart

Brian Linkhart

Dr. Brian Linkhart has been studying Flammulated Owls since he was a graduate student.

The Flammulated Owl is as small as a fist and reticent enough to disappear into the shadows of western forests. Considered the country’s leading expert on Flammulated Owls, Brian has been studying the demography and habitat requirements of this small raptor on the Manitou Experimental Forest since 1981. His aim is the development of conservation plans for forest ecosystems containing this and other sensitive species. With this extended period of study, Brian has been able to uncover some fascinating secrets about this species.

Dr. Linkhart is a Professor of Biology at Colorado College, where he teaches courses in ornithology, ecology and field biology.ace
