The downy woodpecker gives a number of vocalizations, including a short pik call. One may identify the woodpecker by the pik-call, counting half a second between piks (a total of four must be heard). The rattle-call is a short burst that sounds similar to a bouncing ball, while that of the hairy woodpecker is a shorter burst of the same amplitude.
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 female lays between 2 and 7 eggs, which are plain white. The eggs are incubated by both sexes, but the nesting period and other details are unknown. Like most other woodpeckers the ladder-backed woodpecker bores into tree-trunks with its chisel-like bill to hunt for insects and their larva, but it also feeds on fruit produced by cacti.
