"It is fascinating to note that some species have dramatically changed their ranges over a few decades. It is even more intriguing to try to understand which factors have shaped the current distributional patterns, and how these have varied through historical times. For example, some species or groups of closely related species are very patchily distributed across seemingly fairly homogeneous environments, suggesting that they were once more widespread, or that they have successfully colonized geographically disjunct areas. Climatic change, and resulting habitat transformations, have had profound impact on bird distributions."
