VIU Bird Banding Project

I started the VIU Bird Banding project in 2013 with the help of many undergraduate students. Our main project activity has been the bird banding station at Buttertubs West Marsh in Nanaimo. To date, over 150 students and volunteers have been involved in the project.

Education

  • B.Sc. McGill University, Montreal (1991)
  • PhD. York University, Toronto (1996)

Courses

  • BIOL 320 – Aquatic Ecosystems
  • BIOL 325 – Ornithology
