Impacts of future climate change on geographic ranges of North American bird species (<i>n</i> = 588) by 2080 during the breeding (top row) and non-breeding season (bottom row) under SRES A2 scenario.

<p>Changes in total number of species by 2080 due to shifting ranges relative to year 2000 baseline showing potential <b>(a)</b> species gain or <b>(b)</b> loss. <b>(c)</b> Bray-Curtis dissimilarity showing turnover in species composition of local communities.
