Subject: Does anyone know of problem cases of spilled bird seed/pigeon
feed?


With all the bird feeders distributing wild bird seed and pigeon keepers
feeding grain formulas to those birds, a lot of that seed must get spilled
and some must germinate.  Does anyone know of case histories where such
germinated exotic plants spread into ecologically significant distributions?

The reason I ask is that I am using pigeons as bait in a raptor
trapping/banding program and wonder if spilled feed poses a real threat to a
wild area I am working in which has been subject to problems from invasive
thistles, which presumably are not contained in bird seed or pigeon feed.

Thanks for any informed advice.
