Diurnal Activity Pattern of Golden Jackal (Canis aureus Linn.) in an Urban Landscape of Kolkata, India

Abstract

The Golden jackal is known to have a wide distribution range and has been put under “Least Concern” category in the IUCN (ver 3.1) Red Data Book. However, the species once quite common along with the Bengal Fox in the eighteenth and nineteenth century of Kolkata has faced serious challenge due to land use and land cover changes in their urban habitats. As such, the Golden jackal has become “locally endangered” in the city of Kolkata, India. Kolkata, one of the largest cities in India, with population density of 14,112,536 is one such example where the land use change is profound. The Tollygunge Club, Kolkata is a social club with restricted entry at the heart of the city of Kolkata and harbours a healthy breeding population of the Golden jackal (Canis aureus Linn.). The present study focuses on the adaptability of the jackals to human proximity and its capacity to switch to natural food (fruits and leaves of available plants in the club, molluscs etc.) present in the club when the club refuse is not available. Their diurnal activity has been studied. These animals show diurnal activity in the open terrains of the club as they are least threatened by the humans. Only few intraspecific and interspecific (with the stray dogs in the club premises) conflicts have been noticed. In is interesting to note that at the heart of a city, in an urban area, such social clubs with restricted entry can provide suitable habitat to sustain a healthy breeding populations of the animals which are showing constant decline in their population due to change in land use pattern.
