title: The chromosomes of the Hadada ibis and comments on the karyotype evolution in Threskiornithidae (Aves, Ciconiiformes).
abstract: The karyotype of Hagedashia hagedash differs from that of the other ibises karyotyped and introduces further karyotypic variability within the family Threskiornithidae. This variability is in contrast with the generalized karyotypic uniformity of birds and the karyotypic identity displayed by the family Ciconidae, which is closely related to the ibises. A discussion is presented of parameters of ethological structure of the populations that can, in some cases, allow chromosomal rearrangement to be fixed, thereby enhancing ongoing speciation phenomena in the Aves class.
