Avian brood parasitism by Common hawk cuckoo (Hierococcyx varius) and Jacobin cuckoo (Clamator jacobinus) in Bangladesh

Abstract

The avian brood parasitic cuckoo species namely Common hawk cuckoo (Hierococcyx varius) and Jacobin cuckoo (Clamator jacobinus) parasitized the same host species Jungle babbler (Turdoides striata). Breeding season of Jungle babbler started in mid-February and ended in late June which coincides with the breeding season of the parasitic cuckoos, Common hawk  cuckoo (March-May) and Jacobin cuckoo (June-July) respectively. Competition for same host has been found to reduce because these two cuckoo species have different breeding seasons. The common hawk cuckoo and Jacobin cuckoo eggs are not easily identifiable from those of their host Jungle babbler because of a very similar color and size. Maximum number of nests of Jungle babbler was found in Acacia (Acacia auriculiformis). Flock size of Jungle babbler was an important predictor of parasitism in both the cuckoo species with increased parasitism risk in nests at small group size of 4 to 8 members. The host species suffered the costs of cuckoo parasitism, predation and desertion.
