Diurnal activity pattern and foraging behaviour of common kingfisher (Alcedo atthis) in Dal Lake, Srinagar, Jammu and Kashmir
Journal Title: International Journal of Interdisciplinary and Multidisciplinary Studies (IJIMS) - Year 2014, Vol 2, Issue 2
Abstract
The present study documents diurnal activity and foraging behaviour of the common kingfisher (Alcedo atthis Linnaeus 1758) in a human dominated landscape, at the shore line of the famous Dal Lake, Jammu and Kashmir, India. Data pertaining to diurnal activity and foraging behaviour were collected in three time slots starting from 06:00 to 09:00 h, 09:00 to 12:00 h and 16:00 to 19:00 h from June to July in 2013. Activity patterns including feeding, calling, preening, flying, and scanning were recorded and reported in percentages. Similarly, foraging behaviour was studied by observing hunting strategies and associated environmental factors. The percentage of total diurnal activity did not change across different time slots (H = 1.713, P = 0.425) whereby scanning activity consisted of the largest proportion (52.84%) during the time slots, followed by flying (28%) and feeding (13%). Utilization of simple non-feeding perch types and feeding perch types differed statistically significantly (G = 24.42, P < 0.05). Diving from perch sites was predominant (83%) than diving after hovering (17%) by the common kingfisher. Hovering then diving to hunt increases from the morning hours (14%) to evening hours (20%). Foraging success from a perch was 71%, whereas foraging success for diving after hovering was 38% only. Further ecological studies on common kingfisher should be conducted to know more about the species and its interaction with the environment in the human dominated landscapes.
