'Lessons from Avian Haven, a Citizen's Guide to Helping the Birds of Maine'. The upcoming presentation will discuss common reasons why birds are admitted to Avian Haven Wild Bird Rehabilitation Center in Freedom and what public citizens can do to help our local birds. We'll discuss the operation and recent cases of Avian Haven. Summer 2015 admissions include orphaned and injured eagles, owls, hawks, water birds, and many species of songbirds.
