Winter trapping

For the past several years we have had the opportunity of hosting an externship with students from Tufts University studying conservation medicine. Generally we host them over their winter break, where they spend time in the field with senior biologist Peter Bloom learning trapping and handling techniques with a variety of raptors. Here are a few great photos from days out in the field.  Pictured is this years amazing extern Cristen Mathews with a Golden eagle and Red-tailed hawk. If you are interested in an internship, contact us through our website. We value sharing our expertise and mentoring the next generation of biologists, veterinarians and conservationists.
