Although the raising of the young is a matter for men in these birds, parenthood is less expensive for the fathers than thought April 10, Behavioral Biology Evolutionary Biology In the black coucal sex-roles are reversed: Hence, the reproductive-rate of females is limited by the number of males whom they can provision with eggs rather than her own potential to lay eggs. This is remarkable, as the rearing of nestlings is considered to be particularly energy- and time-consuming and males cannot rely on being the true fathers of the young they care for. Scientists of the Max Planck Institute for Ornithology in Seewiesen, the University of Dodoma in Tanzania, and the University of Zurich wanted to find out how much male-only care prevented males from siring young in foreign nests. Females with constantly high reproduction rate A Black coucal male with food. Does parenting hamper the sex life of male black coucals? The male, for whom a female is preparing a nest, guards his partner to secure his genetic paternity, but once the second egg has been laid he needs to start incubation and thus can no longer follow the female. During the most intense period when they had to feed nestlings their chances dropped by 48 percent, and in the period of caring for fledglings by 26 percent. They discovered that the males still had their opportunities to produce additional offspring during the approximately six-week period of intensive brood care, this only happened less often. Thus, the costs of parenting in terms of lost mating opportunities are only moderate, and this has certainly favoured the evolution of male-only care in this species", concludes Goymann. Accordingly, paternity analyses have shown that it is often the later laid eggs that are sired by other males. The males raise the young without help from the female. Grasshoppers, praying mantises and frogs - the main source of food for black coucals - are available in large abundance during the breeding season. The smaller males, on the other hand, hardly sing, but hatch the eggs and raise the young without help from the female. The females of this species are much larger than the males. Despite the large effort for parental care, males still find opportunities to sire young in nests of other males, as a team of scientists led by the Max Planck Institute for Ornithology in Seewiesen discovered. Food abundance is certainly also a reason that one parent alone can provision the young within a relatively small territory. Therefore, due to the rearing of young, male black coucals experience a somewhat restricted sex life, but they never face a complete drop-out of the mating pool. Female black coucals defend large territories with up to five males. It may not be surprising that the black coucal is the only known bird species with altricial young and sole male care.
