have been known to continue roosting on their nests for a period following the breeding season. These birds are normally solitary or in pairs, though sometimes they live in groups of three to five birds. Typically, they silently evade any unusual movements in their forest. However, if these birds know that they have been sighted, they can become quite inquisitive and occasionally approach observers. One of the rockfowl's displays entails several of the birds in a colony forming a loose circle. Individual rockfowl run at each other, forcing the approached bird to retreat slightly before chasing either the bird that charged it or another in the circle. At intervals during this display a rockfowl leans forward on a branch, tucking its head between its legs and half-spreading its wings, thus revealing its crown to the other rockfowl. It is believed that this behavior shows the intent of the rockfowl to roost in a group, though recent evidence suggests that the display could be involved in breeding. To scratch its head, the bird lifts its foot over its wing. This species is long-lived. Diet The white-necked rockfowl forages across slopes on mossy, creeper-covered boulders and in trees covered in lianas and hanging mosses. It occasionally forages by hopping across sand by a stream or even in the stream, as evidenced by crab remains in the rockfowl's droppings. While foraging on the ground, the rockfowl picks up leaves with its bill and tosses them aside. It feeds in mixed-species groups ahead of swarms of Dorylus ants with alethes, bristlebills, and Finsch's rufous thrushes, picking off insects flushed by the ants, mostly off the ground. The rockfowl has also been observed hopping from the ground and snatching prey midair. The diet is diverse and generalized, enabling the white-necked rockfowl to have a degree of adaptability in collecting food. This rockfowl primarily eats insects, including larval cockroaches, tettigoniid grasshoppers, earwigs, ants from the genera Pachycondyla and Dorylus, click beetles from the genus Psephus, and termites. Other than insects, it has been observed eating millipedes, centipedes, snails, earthworms, and occasionally small frogs and lizards. When feeding its nestlings, the rockfowl primarily collects earthworms, small frogs, and lizards, with the vertebrates forming most of the biomass fed to the young. In addition, rockfowl are occasionally seen eating plant material, normally from angiosperms or mosses. Reproduction The White-necked rockfowl breeds primarily in caves and pairs nest either
