Three-toed woodpeckers forage on conifers in search of wood-boring beetle larvae or other insects. They may also eat fruit and tree sap. They may also eat fruit and tree sap. These birds often move into areas with large numbers of insect-infested trees, often following a forest fire or flooding.
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.
The reddish tinge on the belly that gives the bird its name is difficult to see in field identification. [7] White patches become visible on the wings in flight. [ 8 ] Red-bellied woodpeckers are 22.85 to 26.7 cm (9.00 to 10.51 in) long, have a wingspan of 38 to 46 cm (15 to 18 in), [ 7 ] and weigh 2.0–3.2 oz (57–91 g).

Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra.
The pileated woodpecker (/ ˈ p aɪ l i eɪ t ə d, ˈ p ɪ l-/ PY-lee-ay-tid, PIL-ee-; Dryocopus pileatus) is a large, mostly black woodpecker native to North America.

This bird's call is a sustained laugh, ki ki ki ki, quite different from that of the pileated woodpecker (Dryocopus pileatus). One may also hear a constant knocking as they often drum on trees or even metal objects to declare territory. Like most woodpeckers, northern flickers drum on objects as a form of communication and territory defense.
With the likely extinction of the ivory-billed and imperial woodpeckers (Campephilus imperialis), the Magellanic woodpecker is the largest living species of the genus Campephilus. With an average weight of 339 g (12.0 oz) in males and 291 g (10.3 oz) in females, it is perhaps the heaviest certainly extant woodpecker in the Americas. [5] [6]
