I have read elsewhere however that some Pacific islanders have traditionally used tame frigatebirds to carry messages between islands (though having reported that, I'm not too sure about the status of written languages in pre-European Polynesia). Even without such drastic measures as those advocated by Mr Gioura, frigatebirds have become accustomed to humans and their scraps around ports.

The long forked tail and the very long slender wings are the keys to its aerial virtuosity.
Some places in tropical and near-tropical Australia are particularly good places to enjoy them (if you're not a tern). One is Lady Elliott Island, north-east of Fraser Island, where they roost in trees around the shore near the sole resort.
