In mid November in a local park, I had the chance of watching a Mistle Thrush guarding a patch of small rowans laden with berries. The thrush would rattle to fend off a couple of blackbirds that dare land on its tree. Every time it called its rattling call, it would lean forward and flash its tail and wings, displaying its white underneath. It worked! After a while, it settled amidst its bright red bounty. When set to sketch the bird, I was thinking of one of my favourite wildlife artists, the late and inimitable John Busby, who could convey behaviour with a few pencil lines and watercolour washes, and who illustrated the book Birds and Berries by Barbara and David Snow.
