Birds migrate earlier, but some may be left behind as the climate warms rapidly
Date:6/20/2008

ations. Weather in South America has little to do with weather in New England.

Being slow to change in response to warming temperatures could have serious repercussions for long-distance migrant birds. This same research group has shown that plants are blooming earlier in Massachusetts than they did in the past. It appears that the short-distance migrants are keeping pace with this changing environment. However, long-distance migrants are being left behind; as temperatures continue to warm, they will probably experience environments increasingly different from the ones for which they are adapted. Other researchers have already noted that some long-distance migrant birds returning from African wintering areas to breed in Europe are now mistimed with their insect food supply. The inability of some birds to adapt to rapid climate change may be an important factor in some of the declines among songbird populations that have been documented in recent years.
