The Green woodpecker is one of only three types of woodpecker in the UK, the other two being the Great and Lesser spotted woodpeckers. It is the largest woodpecker in the UK with a dense and chunky demeanour; in terms of colour, it is primarily green, as reflected in the name, and features a characteristic red crown and, on the male, a red-coloured moustachial stripe (see comparison of male and female Green woodpeckers below). The tail, unlike other woodpeckers, is somewhat short, and features a subtle yellow-black strip around the edge.
In the UK, they are resident all-year-round and can be observed in most parts of Britain, apart from those northernmost extremities in the Scottish Highlands & Islands, and all of Northern Ireland.
Green woodpeckers are mostly solitary creatures, and may only roost close to each other, rather than together. Pairs of Green woodpeckers bond in March, and can be alone for most of the remainder of the year. They breed in late-April, and it is the duty of both sexes to incubate the eggs.
