TreeSong Nature Awareness and Retreat Center will host a “Birds of Prey” webinar from 6 to 8 p.m. April 16. Instructor Laura Whittemore will lead this virtual class on the many diurnal (active by day) birds of prey found west of the Cascades. From the red-tailed hawk to Cooper’s and sharp-shinned hawks, attendees will get ID tips, natural history facts and resources for further study. The presentation includes the major differences between eagles, hawks and falcons, how to spot raptors and ID them by shape and size, habitat and prey preferences and tips on where to go raptor watching in winter in the Pacific Northwest.
