Barring the presence of an existing hole, downy woodpeckers will create a cavity in a tree roughly 2.4 to 15.3 m (8 to 50 ft) above the ground, [18] with the male woodpecker pecking the hole for roughly half of the daylight hours, in 20 minute work sessions. The nest hole takes about two or three weeks to create, and normally measures 12 to 15 ...
The largest surviving species is the great slaty woodpecker, which weighs 430 g (15 oz) on average and up to 563 g (19.9 oz), and measures 45 to 55 cm (18 to 22 in), but the extinct imperial woodpecker, at 55 to 61 cm (22 to 24 in), and ivory-billed woodpecker, around 48 to 53 cm (19 to 21 in) and 516 g (18.2 oz), were probably both larger.

Usually, pileated woodpeckers excavate their large nests in the cavities of dead trees. Woodpeckers make such large holes in dead trees that the holes can cause a small tree to break in half. The roost of a pileated woodpecker usually has multiple entrance holes. In April, the hole made by the male attracts a female for mating and raising their ...
This woodpecker occurs in all types of woodlands and eats a variety of foods, being capable of extracting seeds from pine cones, insect larvae from inside trees or eggs and chicks of other birds from their nests. It breeds in holes excavated in living or dead trees, unlined apart from wood chips. The typical clutch is four to six glossy white ...
The prothonotary warbler is the only eastern warbler that nests in natural or artificial cavities, sometimes using old downy woodpecker holes. The male often builds several incomplete, unused nests in his territory; the female builds the real nest and lays 3–7 eggs. [17]
