spinifex pigeon

This pigeon lives in rocky habitats and has a crest. The records show that spinifex pigeons are rarely seen on the northern parts of the Arnhem Land plateau but the fact that older Gundjeihmi and Kundedjnjenghmi dialect speakers know of them may suggest that their range has changed or is restricted to southern parts of the plateau.
The formative part bam in the Kundedjnjenghmi name bamkarnamalkmalk  is an archaic form for 'head' in some Australian languages and so the name probably is some archaic reference to the crest on the head, just as the Gundjeihmi name for magpie goose has the bam formative in the name bamurru (and this bird has a bump on the top of its head). The Gundjeihmi name for the spinifex pigeon godjgarnamalkmalk uses the more current form for head godj in the same position.

"The ordinary partridge pigeon is different. The spinifex pigeon lives in the rock country, it's a rock dweller on the flat rocky platforms and has a longer crest, with a feather on its head."
