Abstract
The main objective of the present research was to study the avian diversity, nesting and breeding biology of birds in Fazilka and to carry out morphometric analysis, egg parameters and eggshell calcium in eggs of common birds (Blue Rock Pigeon, Eurasian Collared Dove, Common Myna, Red Wattled Lapwing, Cattle Egret, House Sparrow and Indian Chat) collected from two habitats one with high tree diversity and other with low tree diversity. It was observed that the bird diversity was high in the habitat that supported more tree diversity and low in the habitat with less tree diversity. In habitat with high tree diversity, nesting of total eight species was observed and in habitat with low tree diversity, nesting of total five species was observed. Egg shell thickness (mm) was maximum in Red Wattled Lapwing followed by Common Myna, Cattle Egret, Blue Rock Pigeon, Eurasian Collared Dove and minimum in House Sparrow and Indian Chat. Maximum calcium content in eggshell was found in Blue Rock Pigeon followed by Common Myna, Cattle Egret, Eurasian Collared Dove, Red Wattled Lapwing and least in Indian Chat and House Sparrow. There was no significant difference among the morphometric parameters, eggshell thickness and calcium content of eggs of particular species collected from both habitats (p<0.05). It was concluded that area with high tree diversity provided a better habitat for diversity, nesting and breeding of birds.
