And how will they deliver these coconuts to you? Swallow post? Will they use African or European swallows to make the delivery? Given the weight proportions, I would assume African, but African swallows are non-migratory... And what about delivery time? You would need to know the proper species of swallow so you could determine the correct air-speed velocity to give a proper estimate of flight time duration, factoring in how much the coconut would slow them down, what with having to tie the coconut to their dorsal feathers which would impose quite a bit of drag...
