Karyological studies in four species of ardeid birds (Ardeldae, Ciconiiformes)

  • M. K. Mohanty

Karyotypic analyses of 4 species of birds: Ardeola grayii grayii, Bubulcus ibis coromandus, Egretta garzetta, Nycticorax nycticorax nycticorax (Ardeidae, Ciconiiformes) reveal low diploid values (2n=60–68), absence of sharp bimodality and an unusually large W chromosome in A. g. grayii. N-banding studies in two species (B. i. coromandus and N. n. nycticorax) show 6–8 microchromosomes to contain NORs and the G-banded karyotype of A. g. grayil reveals the usual avian pattern.
