Abstract: (17613 Views)
The Merlin Falco columbarius, is a small falcon widely distributed across Europe, Asia, and North America. Merlin falcons are winter visitors to north India. They occur from an arid area in Gujarat to far northeast Arunachal Pradesh. Here, we present details of the Merlin's diet on winter foraging grounds in Gujarat and Rajasthan, Western India, based on a combination of direct observations from 2009 to 2023 and secondary data extracted from various social media platforms. A total of 99 hunting events of Merlin with their prey bird were collected from the study areas, including 39 generated from direct observation of falcon hunting and 60 images of falcons with prey items acquired from various electronic media. The higher number (72) of falcon hunting events were noted from Gujarat, while a lower number (28) of observations were noted from Rajasthan. Of the total of 99 hunting events, 83 were carried out by males, 11 by females, and 5 juvenile falcons observed hunting. The hunting times of the falcons were noted in the morning (67%), in the evening (28%), and the least (5%) were recorded in midday periods. Merlins hunted and consumed 17 different types of smaller birds belonging to seven families; the highest number (45.45%) of prey items were the Greater Short-toed Lark, Calandrella brachydactyla, from Family Alaudidae and the second highest prey species (7%) was the Barn Swallow, Hirundo rustica, family Hirundinidae. Most of the prey birds were larks of different species (70.70%), with the remaining prey birds in very low numbers. However, the present study supports an earlier study stating that a higher portion of smaller migratory birds are in the diets of Merlin falcons.
