Description: Attend the monthly meeting of the Wyncote Audubon Society. Non-members welcome! Barred Owls are non-migratory, primarily nocturnal, forest-dwelling birds of prey with a strong predilection for old-growth forests, rarely nesting far from some source of water. In eastern North America, their range extends through moist forests from Florida north to the Gaspe Peninsula. The species has extended its range west in parts of Oregon, Washington, most of British Columbia, and southern Alaska and the Northwest Territories, where they pose in some areas an existential threat to the endangered Northern Spotted Owl. Especially in the southeastern U.S., Barred Owls are firmly established in often densely human-population suburban neighborhoods that are old enough to have a canopy of mature hardwoods. Rob Bierregaard and his graduate students studied the thriving population of Barred Owls that have invaded the older suburban neighborhoods of Charlotte, NC. In this presentation, Rob will describe what he and his students learned tracking radio-tagged owls and reviewing hundreds of hours of video recordings from cameras installed in nest boxes. Their data provide a fascinating and detailed picture of the lives of these suburban, nocturnal predators.
The Wyncote Audubon Society is a Chapter of the National Audubon Society serving the nearly 2000 Audubon members who reside in major portions of Montgomery County and Philadelphia including Chestnut Hill, East Falls, Manayunk, Mt. Airy, Roxborough, North Philadelphia and Northeast Philadelphia.
Presenter: Rob Bierregaard is a research associate of the Academy of Natural Sciences of Drexel University in Philadelphia. From 1979 to 1988, working for the World Wildlife Fund and the Smithsonian Institution, he directed—in the heart of the Brazilian Amazon—the Biological Dynamics of Forest Fragments Project, which has been described as the largest and most ambitious ecological experiment ever undertaken.
