Hi All,

VNHS and RPBO have two fantastic guest speakers giving presentations on raptors this week.

BIRDERS NIGHT: Return of the Raptors
Return of the Raptors
Populations of raptors—hawks, eagles and falcons—were decimated by massive applications of pesticides in agriculture and in forestry in the decades following WW II. But their populations recovered after DDT was banned in the early 1970s, and nowadays they are a common sight, even in cities. Top predators like raptors have powerful effects on entire ecosystems, most famously illustrated by the reintroduction of wolves to Yellowstone National Park in the 1990s. Analogously, raptors have effects much further-reaching than the relatively small number of prey they kill. In this talk Dr. Ron Ydenberg (SFU) will relate what we now understand about these effects. Wed Jan 28, 2015 7:30pm – 9:30pm Admission is free. University of Victoria, Fraser Building, Room 159

Raptor Migration - Worldwide Phenomena
Presented by Bill Clark, one of the world's foremost authorities on raptor identification, this slide-illustrated talk on the worldwide phenomenon of raptor migration. More than half of the species of diurnal raptors migrate, but in only a few does the entire population migrate. He'll be discussing the physics as well as the natural history of migration including thermals and slope lift, broad front migration, and water bodies as migration barriers. Bill will have data and photos from around the world. A perfect introduction to raptors! This lecture will be held at UVic in room 159 of the Fraser Bulding on Friday, January 30 at 7:30 pm. Admission is by donation (suggested amount $10).

Both talks are open to the public.
