Climate change spells trouble for many tropical birds — especially those living in mountains, coastal forests and relatively small areas — and the damage will be compounded by other threats like habitat loss, disease and competition among species. That is among the conclusions of a review of nearly 200 scientific studies relevant to the topic. The review was scheduled for online publication this week in the journal Biological Conservation by agan Sekercioglu (pronounced Cha-awn Shay-care-gee-oh-loo), an assistant professor of biology at the University of Utah.
