Faced with climate change, some birds are changing their migration schedules and staying closer to home -- and in the future they might stop migrating altogether. Researchers have found that some birds are shortening their migrations, putting more energy toward breeding and eating instead of flying, and they speculate that eventually the birds could give up migration altogether.
