Are you saying birds were carrying twigs over the Atlantic from Americas -> Europe?? Genuinely curious as to if birds actually do that, seems pointless.
- interestica 5y ago> seems pointless I'm more wondering about the effects of seed/life transfer. Doesn't seem feasible to me.
- hadlock 5y agoEvery year or two, people decide to fly from North America to Europe in a short range Cessna. They get the extra fuel tankage package, then hop from PEI to Greenland, Greenland to Iceland, then Iceland to.... Svalbard, or maybe somewhere in the Scotish Isles. From there it's pretty standard flight operations over local bodies of water. If a Cessna can do it, that's well within a bird's migratory travel distance.
- EamonnMR 5y agoYeah but you think they'd save fuel and locally source the twigs
- scythe 5y agoPossibly not if the goal is to impress a potential mate.
- heavenlyblue 5y agoHave you just invented this or is that actually some well-known fact that birds impress potential mates this way?
- washadjeffmad 5y agoThe joke is that the Cessna fliers are doing it to collect the twigs. If you edit out 'birds', it'd be pure comedy.
- repiret 5y agoI was under the impression that was still the standard way to move GA aircraft across the Atlantic, and happened regularly.

- canadianfella 5y agoThe birds you listed don’t fly across oceans to get twigs.
- aasasd 5y agoA bit different, but IIRC some seeds spread by passing through birds' digestive tract—which sidesteps the bird's decisions on the luggage. However, I'd guess the distance travelled is much shorter in this case.
- sandworm101 5y agoIt doesn't matter whether the birds did or didn't. What matters is that people of the time thought birds were bringing in sticks from somewhere west. People believed there was a land out there. Whether or not the observations behind those beliefs are credible doesn't take away from the fact of their believing there was a land to find.
- sfblah 5y agoI mean, the real question is whether they carried any coconuts.
- riffraff 5y agoBarnacle goose do migrate from Greenland to the British isles, but I do not know if Greenland is considered north America.
- eCa 5y agoYes, Greenland is geographically in North America.
- thaumasiotes 5y agoNot a twig, but there is a recorded case of a bird making it to Europe after being shot with an African arrow. (Which it involuntarily carried with it.)
- distances 5y agohttps://en.wikipedia.org/wiki/Pfeilstorch https://en.wikipedia.org/wiki/Pfeilstorch But that's different, I doubt birds intentionally carry anything from Africa either.
- hutzlibu 5y ago"Before migration was understood, people struggled to explain the sudden annual disappearance of birds like the white stork and barn swallow. Besides migration, some theories of the time held that they turned into other kinds of birds, mice, or hibernated underwater during the winter, and such theories were even propagated by zoologists of the time." Ok, it seems that Aristoteles believed, that birds actually transformed, but zoologist of that time at most believed, that they hibernated underwater", which seems a more solid theory, than transforming.
- thaumasiotes 5y agoTransforming isn't exactly unknown; all insects do it.
- hutzlibu 5y agoYes, but by the 18.th century, we knew that birds and mammals are a bit more complex than insects and quite shape stable.
- thaumasiotes 5y agoShape stability would be an example of being less complex than insects. And as you can see, we did not in fact know that in the 18th century. Transformations are not so easy to observe directly; they often happen e.g. underground.
- jobigoud 5y agoAnother piece of land to the west before the Americas is the Azores archipelago roughly half way between Europe and Newfoundlannd. Maybe the bird came from there. This was known to Europeans well before Colombus trip.
