They used Great T**s from non-urban and urban areas, and mixed them up through breeding, to rule out any possible family history of telomere length. The benefits are many, including the availability of anthropogenic food sources, breeding boxes and warmer temperatures. Research done quite a while back suggests that this is adaptive.

You don’t really know a bird until you’ve studied it on its breeding grounds. Getting intimate with a species over the course of the breeding cycle is one of the more rewarding aspects of birding, and field research too. Color markings on the legs and head are to identify individuals for research purposes).

My research in the Congo supports this idea. I spent a lot of time with Efe Pygmy hunters in the deep forest, and I spent a certain amount of time either entirely alone or with only one other researcher, this or that American. Part of that research was to document human avoidance by ground mammals, and that was stark and apparent.

The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. Like most maps, colors are used to indicate seasonal status (breeding resident, Austral migrant/visitor, Boreal migrant, etc.). Distribution maps are also different from other field guides.

So, while waiting for evolution to produce new birds for our life lists is inadvisable, we sometimes catch a break and every few years get a new species or two when some genetic research or study of breeding distribution presents enough evidence to split what was once considered a single species into a few new ones.
