I interviewed Rob Butler, ornithologist, and author of the book “The Great Blue Heron.” He was a wealth of information and stories.
Ross Vennesland was also an interviewee. Ross is an ecosystem scientist with Parks Canada, and has written many papers on herons and heron colonies. He has had a lot of influence on heron conservation.
Robyn Worcester is a long time friend and biologist with the Park Board. She was a conservation specialist with the Stanley Park Ecology Society, wrote an extensive State of the Park Report, and drove monitoring of the great blue heron colony in the park.
