Abstract

Chromosomal analysis of two species of Indian birds, Vanellus spinosus (Charadriiformes) and Lanius cristatus (Passeriformes) showed their 2n values to be 58 and 72 respectively. In Vanellus spinosus there are 11 pairs of macrochromosomes (7 pairs of m-type, one pair of sm-type, 2 pairs of t-type and ZW) and 18 pairs of microchromosomes. In Lanius cristatus there are 10 pairs of macrochromosomes (one pair of m type, 3 pairs of sm-type, 5 pairs of t-type and ZW) and 26 pairs of microchromosomes. In both the species Z chromosome is m-type and W chromosome is sm-type. The total chromosomal length in V. spinosus and L. cristatus are 36.76 mm and 40.05 μm respectively.
