Abstract:

Abstract 10.1002/zoo.1430110409.abs Chromosomal variation within bird species has been rarely studied. Having studied three individuals, I report a difference in the length of Z-chromosomes in one male eagle owl (Bubo bubo) and use C- and R-banding to study the variation between these Z-chromosomes. Absence of non-centromeric heterochromatin in one Z-chromosome is the cause of the difference in length. The presence of two types of Z-chromosome in this eagle owl may reflect hybridization of animals from different subspecies, or might be caused by a spontaneous deletion of C-band positive DNA. © 1992 Wiley-Liss Inc.
