Hummingbird

A hummingbird is smaller than your thumb and weighs less than a 20 pence piece – however you measure it, it’s tiny. But every spring, hummingbirds that have spent the winter in Mexico fly north to make the most of the warmer weather. They nest as far north as Canada and Alaska; a 2,000 mile trip! This is the story of one spring migration: of a tiny bird, its amazing journey and the people it meets along the way
