Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.

Bill Oddie presents the great crested grebe. In Spring, great crested grebes perform a high ritualized mating display. This includes head shaking and a spectacular performance during which both male and female birds gather bunches of waterweed and as they swim towards each other, before rising vertically in the water, chest to chest, and paddling furiously to keep themselves upright.
