Jan. 3, 2011 I watched a Northern Shrike visit a few trees in our yard. This is my 3rd sighting since mid-December, 2010. We have many feeders, thus many small birds. Is this what attracts the Shrike? Also, as it flew away yesterday, a few other birds followed- I wasn't able to identify them. Is it possible they travel in groups, or is it more likely that other birds were chasing it away? Thank you!
