Climate change is altering North American winter bird communities in ways that models currently favored by ecologists fail to predict. Based on patterns of animals found in different climate zones today, ecologists would expect that as habitats warm, numbers of species found there will increase, and that those species will be smaller in size and restricted to narrower geographic ranges. Ecologists at the University of California, San Diego have found that only one of those three predictions has held for North American birds over the past quarter century.
