One of the West Park magpies in a patch of long grass near the Conservatory. The greylag goslings, recently hatched and still tiny when these pictures were taken, were in the same patch of long grass being guarded by three adults.
I had my suspicions that the magpie was after bigger prey than insects hidden in the grass. So did the adult geese, who made sure the magpie never got too close to the young ones.
