KC Tsang was at the Sungei Buloh Wetland Reserve on 7th September 2008 when he encountered a raptor catching a Pink-necked Green Pigeon (Treron vernans).
“We had a bit of drama and excitement at the carpark of SBWR, 12.50pm, as I was packing my equipment to leave, a raptor swooped on to a sleepy Pink-necked Green Pigeon on a branch just above us. A visitor yelled ‘The eagle has got something.’ So got my gear out of the boot, and started taking pictures. However a family nearby also saw where I was pointing my camera, started making a lot of commotion thus ended the whole drama when the bird flew away with his prey. ”
The raptor was a sub-adult Rufous-bellied Eagle (Hieraaetus kienerii formosus), a rare winter visitor and passage migrant. Its range includes Myanmar, Indochina, Thailand, the Malay Peninsular, south to Sumatra, Borneo, Java and the Lesser Sundas and the Philippines (Wang & Hails, 2007). In Singapore it is a rare winter visitor and passage migrant, arriving from early August to early May, reportedly together with migrating sparrowhawks and honey-buzzards (Wells, 1999).
This raptor is a typical aerial hunter, taking prey on or near the ground or on treetops, usually after a spectacular swoop. Cook (1911) reported a bird crashing through the foliage onto a party of green-pigeons in Myanmar. Chasen (1939) reported the raptor attacking Domestic Fowl, Town Pigeons, Pacific Golden Plover and Black-capped Kingfisher. Thiollay (1994) on the other hand documented the eagle taking birds like pheasants, junglefowl and pigeons, as well as mammals like squirrels.
