UNUSUAL FORAGING BEHAVIOUR OF AMUR FALCONS

Amur Falcons Falco amurensis are non-breeding Palaearctic migrants (Nov-May) to the eastern parts of Southern Africa. This species forage mainly by perch-hunting as well as hover

over open grass- and croplands. On non-breeding

consumes almost exclusively arthropods (locusts and grasshoppers, termite alates, beetles, bees); they may occasionally capture birds (Jenkins 2005).

It was therefore surprising to observe 4 of these birds that were were apparently foraging in a manner very similar to that of Whiskered Terns Chlidonias hybrida. These observations were made on 6 January 2012 around 16:40 at a farm dam south of Klerksdorp (26 52S 26 32E). Terns normally hover and plunge

surface-dip, snatching insects from above water surface and picking amphibians and invertebrates from vegetation (Hockey 2005

It could not be established what prey they were foraging on

birds repeatedly dived into the water, immersing their legs all the way to their bellies. They appeared to have something in their claws as they left the water. The distance to the birds was such that I could not identify what they were foraging. They repeated this behaviour for approximately 45 minutes.
