✦ Synopsis

The karyotype of the osprey consists of 74 chromosomes. There are no large macrochromosomes and no typical microchromosomes. Autosome No. 2 has a prominent secondary constriction in the long arm. The Z chromosome is similar in size and shape to the largest autosome, the W is a small metacentric. Among the Falconiformes, the osprey karyotype mainly resembles the karyotypes of some accipitrid species. However, certain characteristic features of the karyotype, a unique secondary constriction chromosome and absence of microchromosomes, speak in favour of maintaining the osprey in a family of its own, Pandionidae.
