American Golden Plovers Are Smuggling Plants into Australia5 comments to American Golden Plovers Are Smuggling Plants into Australia |

Indeed. The summary of the summary is: “Since the days of Darwin, biologists have questioned why certain plants occur in widely separated places, the farthest reaches of North American and the Southern tip of South America but nowhere in between. How did they get there? Researchers have now found an important piece of the puzzle: migratory birds about to fly to South America from the Arctic harbor small plant parts in their feathers.” So, the point is that migratory species may, in some cases, be the reason for spatially separated populations of plants that don’t have an obvious historical connection (e.g. they exist at high latitudes in both hemispheres.)

There are a couple of species of plants that are found in Greenland / Arctic Canada and a few sites in North Scotland, presumably brought to the latter as seeds on the feet or in the stomachs of migrating geese.

Oh Ok ! What would be more plausible and interesting would be to know if Pacific Golden Plovers do the same thing. It might be a bit different though as they are more of a coastal species when not breeding – whereas American Golden Plovers like grasslands more in South America. Hence species they transfer might be more likely to survive?

Hi guys, Laurie’s mails were obviously marked with
and 😉 I guess that his humorous point is that there are a few accepted records of AGP in Australia, and why can’t they smuggle North American plants into Australia if the can do that to South America? It would certainly be interesting if PGP and other Siberian shorebirds do the same on ‘our’ flyway.

I think what Laurie was inferring from the article is that if AGPs transfer plant material between N America and S America, then this proves that they can do it. The inference is that the same species could conceivably (and probably likely) be doing the same thing between other continents it visits, albeit as a vagrant.
