Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Mute Swan
Lakes, slow rivers, estuaries, and coastal lagoons. Often associated with parks and ornamental waters in Europe.

A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.

Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
Mute Swan
All-white plumage in adults. Cygnets are grey-brown, gradually whitening over the first year. Graceful S-curved neck posture is distinctive.
Orange bill with a prominent black knob at the base, larger in males
About These Birds
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
Mute Swan
The mute swan is one of the heaviest flying birds, with males weighing up to 14 kg. Despite its name, it is not truly mute, producing hissing, grunting, and snorting sounds. Mute swans form lifelong pair bonds and their aggressive defense of nesting territory is well known.
