(Brad Davis/The Register-Herald) Three Rivers Avian Center executive director Wendy Perrone stands by to answer any questions passing visitors might have about Regis the bald eagle or Hoolie the great horned owl, who both sit next to her during a Spring Migration Celebration Saturday morning at Little Beaver State Park. TRAC brought veteran travelers Regis and Hoolie along with a couple of other raptors along to the annual event, which also featured educational games and activities designed to teach kids the importance of all of nature's creatures.
