Another note on the 1080 poison, I was at a conference where David
Peacock presented a paper entitled 'Can native animal bones retain a
natural plant toxin, becoming lethal to the feral cat and fox?'
He said that there is anecdotal evidence that bronzewing pigeons
accumulate the 1080 toxin in their skeletons as a result of feeding on
the seeds of the plants that contain the toxin, and that foxes and cats
are apparently killed by the toxin when they kill and eat the birds. It
suggests at least that bronzewing pigeons have a high tolerance level of
1080.
