Ornithological studies confirmed that 83 species belonging to 16 orders were present in and around the wheat fields from preparatory tillage to ripening stage at village Ruldu Singh Wala, Katar Singh Wala and Bir Talab. The diversity analyses revealed a richness index of 77, 58 and 55, respectively. Rose-ringed parakeet was the most abundant at all the locations (10.53, 25.51 and 21.30%, respectively) followed by blue rock pigeon (7.57, 14.19 and 10.80). Passeriformes (46.99%) was the most dominant order followed by Cicioniiformes (12.05%) and Charadriiformes (8.43%). Insectivorous guild (39 species, 46.99%) was the dominating guild followed by omnivorous (19 species, 22.89%) and carnivorous guild (12 species, 14.46%). Species number increased from early (preparatory tillage and sowing) to late (seedling and ripening) stages. Thus, it is observed that wheat crop acts a major habitat for birds.
