Global warming forces Birds to higher altitudes.
Global warming forces Birds to higher altitudes and not necessarily to higher latitudes....
finds a study.......
birds aren't migrating as rapidly as scientists previously anticipated, based on recorded temperature increases.
"However, our understanding of the response of tropical birds to warming is still poor," said German Forero-Medina, a Ph.D. student at Duke's Nicholas School who is lead author of the new study. "Moving to the north doesn't help them, because tropical temperatures do not change very much with latitude. So moving up to higher elevations is the only way to go, but there are few historical data that can serve as baselines for comparison over time."
