Another big flightless pigeon, the Rodrigues solitaire, is described in an article at
www.bbc.co.uk/news/science-environment-42057143 It had a bony growth on its wing which it used to fight othe solitaires, but that was no use against the introduced rats and cats which ate its eggs and chicks. Apparently the Victoria Crowned Pigeon also has a growth on the wing-wrist (but smaller than that of the solitaire) that it uses for defence. I didn't known that.
The article was inspired by research for the radio documentary 'Can we revive extinct species like the Dodo?' CrowdScience was on the BBC World Service at 20.35 on Friday 1 December. You can download the CrowdScience Podcast to listen on demand at www.bbc.co.uk/programmes/p04d42rc
