My mother is a bird enthusiast. I say this because she doesn’t have the education to be considered an ornithologist, or the constancy of habit to earn the title of birdwatcher. But she knows more about birds than anyone I’ve ever known; excluding my year eight maths teacher, who was the world’s leading specialist on bowerbirds, and my Nanna Nancy, who was our family’s leading specialist on just about everything up until she died a few years ago.
