Dato’ Dr Amar-Singh HSS reported seeing seven Cotton Pygmy-goose (Nettapus coromandelianus coromandelianus) around old mining pools in Gopeng’s Gua Tempurung in Perak, Malaysia on 29th December 2009. The image above shows the seven flying around, with a Stork-billed Kingfisher (Halcyon capensis) perching in the foreground. Together with the these geese in the pond were a Little Grebe (Tachybaptus ruficollis) and two Lesser Whistling-ducks (Dendrocygna javanica).
“There is some doubt/uncertainty about the Cotton Pygmy-goose breeding locally,” recounts Amar. “My opinion is that there were two adult males (but both did not have a clear prominent black collar), three immature/eclipse males (above left), one adult female and one immature/eclipse female (above right). This might suggest local breeding, but could still be a migratory flock.”
“…My analysis suggested migrants at this time of year although no-one knows how far south pigmy-geese still breed,” writes Dr David R Wells. “Perak could well be within the range, but note that they need hole in waterside tree. Not the sort of thing mining pond sites can often supply?”
