Dactos are recurring enemies in the Legend of Zelda series. They are birdlike reptilian monsters, pinkish in color, with a horn growing from their forehead and a crest on the back of their head. They usually wait on trees or ledges and fly down to attack Link when he walks near.
Dactos are closely related to Ravens. In Japan, both Dactos and Ravens are referred to with the same name, Kyune.
Dactos are the Dark World counterparts of Crows. They deal six times as much damage as Crows and take twice as much damage to defeat. Unlike Crows, they will continue to attack Link until he defeats them or leaves the screen, rather than flying away.
They were never officially named in A Link to the Past, and were often called Ravens due to the shared Japanese name before A Link Between Worlds gave them an official name.
The name 'Dacto' is probably derived from pterodactyl, a prehistoric flying reptile that lived alongside the dinosaurs. Dactos were already similar in appearance to pterosaurs before being named in English; the name was likely derived from the monsters' appearance.
