Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Chris Packham presents the red-breasted goose in Siberia. Red-breasted geese are colourful birds with art-deco markings of brick-red, black and white. Despite their dainty and somewhat exotic appearance, these are hardy birds which breed in the remotest areas of arctic Siberia. They often set up home near the eyries of birds of prey, especially peregrine falcons. But there's method in the madness; These wildfowl nest on the ground where their eggs and chicks are vulnerable to predators such as Arctic foxes. But the ever vigilant peregrine falcons detecting a predator, will defend their eyries by calling and dive-bombing any intruders, and this also doubles as a warning system for the geese. In winter red-breasted geese migrate south where most of them graze on seeds and grasses at a few traditional sites in eastern Europe around the Black Sea.
