- Comment "Most birds have four toes (anisodactyl toe arrangement), with three facing forward and one back, but some birds’ toes are adapted to suit different needs. Woodpeckers, for example, have two set forward and two back, to brace themselves firmly against a vertical tree-trunk. Many game birds, and domestic chickens, have a fifth toe with a sharp claw that they use for fighting rivals. Reference: Birds' legs and feet. Royal Society for the Protection of Birds (RSPB), https://www.rspb.org.uk/birds-and-wildlife/natures-home-magazine/birds-and-wildlife-articles/how-do-birds-survive/birds-legs-and-feet/ [21.2.2018] Not all birds have this same ability to grasp branches (e.g. some birds, like geese and ducks, have webbed feet).
