What about African coconuts versus European coconuts? So, rob, are you suggesting different migratory patterns for the African and the European swallow?

After all, one good tern deserves another. @Ford - How do they get their zinc? Electrolosis. Just take apart that 1g geolocator and put the parts to good use. Oh, you meant how would the pre-geolocator terns get THEIR zinc. Well, how do we know the pre-geolocator terns were galvinized? To every thing (tern, tern, tern) there is a season tern, tern, tern...

And how do they obtain the needed zinc in the middle of the ocean? Great story, though. Coconuts migrate without help from birds, via ocean currents, where they float even better than witches.

And are the predators’ ranges extending northward with climate change?

Python et al did a similar study in the 70's. they showed a five ounce bird could not carry a 1 pound coconut, even if gripping it by the husk. in order to maintain air-speed velocity, a swallow needs to beat it's wings 43 times every second. only non migratory african swallows acting in unison were shown to be able to carry a coconut using a standard creeper held under the dorsal guiding feathers.
