In a 2001 study of captive village indigobirds from Africa, he and his colleagues fostered nestlings with two host species: the red-billed firefinch, which these indigobird parents would target in the wild, and the Bengalese finch, which these indigobirds wouldn't naturally encounter.
Musical taste, rather than geography, may have split Africa's indigobirds into multiple species, and a new analysis gives a genetic underpinning for that idea.
This scenario puts indigobirds among the few vertebrates for which scientists have strong evidence that species divided without some geographic barrier looming, says Michael D.
Indigobirds, which belong to the genus Vidua, lay their eggs in other birds' nests, targeting the hospitality of particular species.
In the field, each male indigobird was tape-recorded to determine its mimicry songs.
In addition to males whose songs we taped, we collected in Cameroon a juvenile indigobird at a call-site of an adult V.
- Three types of constraint analyses were done with heuristic searches, all using the complete Vidua dataset: (1) paradise whydah relationships constrained to match the topology of their Pytilia hosts; (2) each individual indigobird included as a taxon on the Vidua tree and constrained such that each species in S-C Africa was monophyletic; and (3) each individual indigobird included as a taxon on the Vidua tree and constrained such that each species in Cameroon and each song form of V.
In addition, the genetic distances between geographic replacements of indigobirds that parasitize the same host species in different regions of Africa were about the same or greater than the genetic distances between different indigobird species (which each parasitizes a different host) within a region.
