A total of 1,623 records of migrant raptors spanning 21 species were obtained in the year 2016. The Oriental Honey Buzzard topped the chart with 1,200 records. The Black Baza was a distant second with 178 records, followed by the Japanese Sparrowhawk with 125 records.

Dropping down to double digits, there were 31 records of the Osprey, 27 for the Peregrine Falcon, and 22 for the Chinese Sparrowhawks. Do note that the Osprey comprise winter visitors and non-breeding visitors and the same few birds may have been recorded month after month. The Peregrine Falcon comprise a mix of winter visitors and passage migrants, while a greater percentage of Chinese Sparrowhawks are passage migrants.

In the single digits (consider yourself very lucky if you had seen these !), there were the Booted Eagle & Jerdon’s Baza with 7 records; the Common Kestrel with 5 records; the Rufous-bellied Hawk-Eagle with 4 records; the Northern Boobook & Common Buzzard with 3 records; and the Eastern Marsh Harrier & Black Kite with 2 records.

Now for the single records (it’s like striking lottery, isn’t it?), there was the Amur Falcon, Eurasian Sparrowhawk, Grey-faced Buzzard, Pied Harrier, Oriental Scops Owl, Eastern Imperial Eagle, and the huge Himalayan Vulture.
