And that the labradoodles have established a meaningful population.

Given the different behaviors and appearances of labradoodles to poodles or labs, I don't think it is as insignificant as you think.

Like most science, it is easy to imagine, but observing it happening in the wild is new. Additionally, in this case, the bird was not simply a mixture of the properties of the two parent species:

the newcomer, a male that sang an unusual song and was much larger in body and beak size than the three resident species of birds on the island

Edit: as dortex pointed out, that quote is regarding the new bird on the island that apparently flew in over a strait or something. Not the new offspring.

Actually, that was one of the parent species. That bird bred with a native and made the hybrid.

Ah, you're right. When they're talking about the new beak morphologies it isn't clear if they mean specifically within the island or also including the "Big Bird" progeny itself. I have questions. :-)
