The resource utilization patterns in the Indian fox (Vulpes bengalensis) were studied with respect to diet in Kutch, Gujarat. Resource use and availability by foxes were compared between two habitats (scrubland and grassland) and between two seasons (winter and summer). Resource availability was quantified through transects laid in both the habitats for the different prey items: mainly mammals, birds, reptiles, arthropods and fruits. Scats collected from den sites were used to quantify resource use by the Indian fox. The minimum number of scats that can be used to estimate the annual food habits of the Indian fox in a dry arid area like Kutch is about 110 scats. The food habits of the Indian fox comprised of varied items, mainly arthropods like coleopterans (beetles), orthopterans (grasshoppers & locusts), arachnids (scorpions) and isopterans (termites). Among the other items, rodents, hares, spiny tailed lizards, birds and eggshells as well as fruits have been found. Arthropods were the most frequently occurring prey items (>75%), particularly the termites. Methods used to compare use versus availability (Ivlev’s Index, Bonferroni’s CI, and Compositional Analysis) showed the arthropods to be selected more than availability within the habitat. However the Indian fox probably maximizes its energy requirements by selecting mammals next in the preference.  

Density of breeding units evaluated in the study area was 0.10/sq km. The density of breeding pairs obtained in this particular study was much higher as compared to the ones reported earlier for Kutch

(0.04 - 0.06/sq km) due to good rainfall in the preceding two years thereby indicating a good prey base as compared to other years
