Goldcrest

• comportamientoIt is one of the smallest birds in Europe and yet, for all its size, some populations migrate hundreds of kilometres, crossing even the North Sea.
• It is the smallest bird in Europe, at about six grams, and even so it breeds in forests where winter drops below twenty degrees under zero: to survive the night it has to eat almost its own weight in insects every day.
• It lays up to eleven eggs in a clutch, one of the largest of any European passerine, in a hanging nest of moss and cobweb the size of a golf ball.
• In winter it sleeps huddled with other goldcrests in a tight ball among the branches, sharing body heat to survive the coldest nights.
