Thanks Laurie
I do not think we have to go as far as Peru to see this effect. In
New Guinea, some swiftlets in the highlands nest on the floor of
caves instead of the ceilings, as there are (were) no snakes up
there. You can download my short note on this by clicking on my
1990a paper "An unusual nesting habit for swiftlets". it is towards
the end of this page: http://www.swiftsoftheworld.info/spplist.htm
Enjoy life before the snakes take over.
Cheers
Mike
