Gosh is it 2003 already.
Waitomo Adventures in New Zealand used pigeons for transporting camera cards approximately 1.571 eons ago.
This isn't news.
(I wonder if they still use them? A quick peek didn't show it on their site - only some annoying pop-up flash)
NB: I'm quite prepared to be proven wrong about the 'first' part - I researched this almost as long as it took to type this in.
