Geocolaptes olivaceus (Ground woodpecker) Both sexes excavate the nest, which consists of a 0.5-1.0m long tunnel ending in a circa 15 cm wide egg chamber. It is usually dug into earthen banks, such as riverbanks and gullies, or in crumbling walls of abandoned buildings or termite mounds.
Red-throated Wryneck (Jynx ruficollis) is an ant-eating specialist with adaptations to assist in the mopping up of large numbers of Hymenoptera (Ant) prey. This bird’s long tongue is capable of extending more than 60 mm past the tip of the bill and covered with a sticky mucus secretion from the salivary glands. This weapon is flicked out at amazing speed to gather beakfuls of ants for delivery to hungry chicks. Photo by Hugh Chittenden.
