Hi Martin,
I once spoke to a Geologist and an Australian museum curator about this.
Apparantly some birds actually eat stones to aid in digestion. Go figure!
;-)
Cheers,
Jeff

Hola list,
I have a stupid question for the ornithologists.
Does it happen, that birds are throwing with stones?
At least once per year I get an email from people, who swear to have heard a
stone hitting the roof and rolling down,
recently again and the stone even should have had a red mark, where it hit
the tile. The stones are quite small, often round or egg-shaped.
I remembered an article years ago, reporting that a group of magpies caused
troubles in the Netherlands, frequently damaging parking cars in dropping
stones.
Can this story be true and if so, what are the reasons for such a behaviour?
Martin
