FORKTAILED DRONGO MARAUDING MANNIKINS

The Fork-tailed Drongo Dicrurus adsimilis is known to prey on Bronze Manniken Lonchura cucullata (Dean, 2005). This paper discusses this behaviour with photographic evidence. It also notes the capturing of the 2 other species of Mannikin by the aggressor.

The first observation of a Drongo preying on Mannikins was 2011 when a Forktailed Drongo flew into the garden

KwaZulu-Natal. It perched in a tree and watched the 3 species of Mannikin feeding at the feeders and perching in the tree

feeders. The Drongo swooped down, “talons” at the ready and grasped a Bronze Mannikin perching in the Flat-crown

Drongo then flew off to a Eucalyptus tree about 200 m away

perched. It started pecking at the Mannikin which was still flapping its wings. This continued until the Mannikin was dead, whereupon the Drongo plucked the feathers and consumed the Mannikin piece by piece. The accompanying pictures document this preying of a Drongo on Mannikins.

The same behaviour was since recorded on numerous occasions Later in winter the Drongo had been observed

attempting to capture Mannikins every morning. Invaria Drongo fails to capture a bird, he scared the Mannikins directions. Occasionally some of the birds flew into windows attempted escape. The Drongo would then swoop down

dead or stunned Mannikin. It would pluck the prey before consuming it. It did not discriminate between the different species of Manniken.

The Drongo regularly flew to the same tree where it c prey.
