Haematological study of adult female Indian runner duck and Japanese quail was conducted to evaluate the variation between two different poultry birds having different habitat. Results obtained in case of Japanese quail showed a higher total leucocyte count (p<0.05), lower haemoglobin value (p<0.001) and erythrocyte count (p<0.05) in comparison to Indian runner duck. Aggregates of RBC and deformed monocytes were also observed. This present study will be helpful in better understanding of different poultry birds having different habitats.
