About These Birds
African Cuckoo
African Cuckoo (Cuculus gularis) — 32–35 cm. Very similar to Common Cuckoo; grey above; barred below; yellow bill base and orbital ring; long tail. Migratory intra-African breeder across sub-Saharan woodland and savanna. Brood parasite primarily targeting fork-tailed drongos. Insectivore.
Saint Helena Cuckoo
Saint Helena Cuckoo (Nannococcyx psix) — ~25 cm. Extinct. Known only from subfossil remains from Saint Helena, South Atlantic. A small cuckoo inferred from bone morphology; likely became extinct following human colonisation of the island in the 16th century and the introduction of predators.
