Great-tailed Grackle (Quiscalus mexicanus). Ugly bird. There are places in San Antonio during the winter where you have to take an umbrella to walk around, even if it's not raining.![]()
Oh my, Quiscalus? I've even sequenced that genus! And I usually look up pictures of everything I sequence, as the material is my supervisor's, and i don't always know what it is he's working with. But I can't remember that one.
Could we request, respectfully, that Europeans keep your birds at home in the future?![]()
European starlings and house sparrows were both introduced into North America and we didn't really need them. They've become the bird version of the rabbits in Australia, or kudzu vine in Georgia.
Interestingly, the introduction of starlings to old British colonies around the world is an excellent example of what known as the "missing the boat" effect, a kind of bottle neck effect on a higher level. In Europe, the starling is parasitized by five different species of jawed lice --- Brueelia nebulosa, Menacanthus eurysternus, Myrsidea cucullaris, Ricinus alongatus, Sturnidoecus sturni (1) --- but in the American population, only two of these can be found (2). Passerines usually have a quite low infection degree, because they can clean their feathers more efficiently than other birds, and by coincidence, the original population introduced to North America were parastized only by these two species.
Louse trivia of the day has now ended.
If there's anything we sent over there that you didn't want, I'm sure we'd be glad to take them back in exchange for your coming to get these birds.
Well, there's the Canada goose, of course...

(1) B. ochroleuca, Me. mutabilis, S. leontodon are junior synonyms of the other species of their respective genera.
(2) I think it is the Myrsidea and the Sturnidoecus, but I'm at home now so I can't check. The relevant article is "Boyd, 1951. A Survey of Parasitism of the Starling Sturnus vulgaris L. in North America. Journal of Parasitology 37(1), 56-84 "
