and its head looking up. Typically, it silently evades 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. This is not a shy species once it knows that it has been seen, and often studies things of interest, including humans, from an open location. When this species is suspicious, it raises the small crown on its head and the ruff on its neck while uttering a muffled groan. It is most active in the early morning and late evening, and from 10:30 am to 7:00 pm remains perched with little activity either in liana-tangled areas or in caves away from the nests. To scratch its head, the species lifts its foot over its head. It bathes in small pools. While its lifespan in the wild is unknown, it has lived up to 25 years in captivity. Diet This species forages in the early morning or late afternoon either alone or in small groups in leaf litter and on dead tree trunks. It is also known to leap upwards to grab prey on overhanging foliage. It looks for its prey either by standing still and scanning the surrounding area or by tossing the leaf litter away with its beak. It also frequently follows columns of Dorylus ants, feeding on the insects flushed by the ants. It also is known to hunt in streams for crabs and fish. It crushes snails with its beak and, if its prey struggles, smashes it against the ground. While an uncommon occurrence, male rockfowl have been observed giving food to a female. The grey-necked rockfowl feeds on a diverse range of invertebrates and small vertebrates, though plant matter does constitute a major part of its diet. It is known to eat beetles, including weevils, rove beetles, and click beetles from the genus Psephus, butterflies, ants from the genera Dorylus and Pachycondyla, grasshoppers, cockroaches from the family Blattidae, earwigs, caterpillars, ant-lions, silverfish, and earthworms. Small lizards, frogs, snails, and slugs are also eaten, as are crabs from the genus Potamon, fruits, flower buds, mosses, and leaves. Fish have also been identified as a prey item in Nigeria. At at least one nesting site, it relies heavily on the arthropods feeding on the bat guano near the cave for sustenance, while this behaviour has been reported to a lesser extent at other
