| dc.description.abstract | The present study was undertaken to investigate the various habitat preferences of the black and grey partridge in crop land ecosystem, the predominant ecosystem of the state. In addition the breeding biology which included the courtship behaviour/ pair formation, nesting sites, nest formation, egg laying and clutch size of these birds was also studied. The study was divided into three experiments, in the first experiment, the habitat preferences of black and grey partridge in different crop lands were studied and later, the breeding behaviour and the nesting sites and the number of nests of these birds were studied in the second experiment, and then lastly, the breeding biology i.e. the egg laying and clutch size of both the birds were studied. The study areas included orchards, crops like wheat, bajra, maize, mustard, sunflower, shaftal, sorghum, barseem, mulberry, cotton etc. In forestry area trees like poplar, jatropa and bushy area were grown. In dairy farm area, it was fodder and bajra. During the entire course of study both the black and grey partridges were observed for their activities like foraging, feeding, breeding etc. In the new orchard area, the crops of bajra in fodder section area and dairy farm area, a comparatively higher number of black partridges were observed. This indicated the suitability of these three crop habitats for black partridge. In case of grey partridge, the most suitable area was fodder section area having the crops like bajra, maize and sorghum. The number of grey partridge sighted were much more and with greater frequency. Like black partridge, their numbers increased after the breeding season in the month of August to October. In this study, 4 nests of black partridge and 5 nests of grey partridge were observed and the clutch was between 8-13. The present study concluded that black partridges were found in specific habitats while the grey partridge was a true generalist species having the capacity to adapt to a wide range of habitats and environmental conditions. The density was found to vary between different habitats on the basis of vegetation characteristics. The grey partridge of these birds was found to be far more in numbers as compared to black partridge in all habitats. The black partridge was found in the habitat area which was highly dense, very less or even no black partridge was seen in the area having the habitat covered with trees whereas grey partridge was found in every type of habitat.
