The public is invited to attend the Yolo Audubon Society’s monthly meeting Wednesday to hear Michael Perrone speak about the changes undergone by local bird species populations.
Perrone will draw from his voluminous personal field notes and historical records to chronicle changes in Yolo County bird populations. Local residents are invited to come enjoy his photos and learn about the success stories of some bird species and the challenges facing others.
“Not many people are fully aware of the enormous changes in abundance, distribution and diversity experienced by the birds of Yolo County in the past 50 years,” a news release said. “For example, mountain plovers were once regular visitors to Yolo County during winter, but now, this species is virtually absent.
“On the other hand, Swainson’s hawks are far more numerous than before. It is possible that the changes to these two bird populations may be related.”
Another example of possibly related changed bird population, the release said, is that purple martins are now extinct in Yolo County’s oak woodlands, while white-throated swifts have moved in to occupy highway overpasses.
Yolo Audubon meets monthly on the third Wednesday at the Davis Senior Center, 646 A St. The program begins at 7:30 p.m. All are welcome for cookies, coffee and conversation at 7 p.m.
The Yolo Audubon Society is an all-volunteer, nonprofit organization dedicated to fostering an appreciation of birds and other wildlife through educational programs and field trips, bringing conservation issues to public awareness and acting to preserve Yolo County bird life and habitat.
