Wild update: Arctic birds are literally speeding up their migrations to keep up with rapid warming. Researchers tracked geese and swans with GPS and found they’re cutting down on rest and meals just to arrive at breeding grounds on time. Some species are adapting better than others, but the clock’s ticking—scientists say they’ve only got a couple decades before this strategy stops working. If they can’t keep up, we could see fewer birds and less successful breeding. Nature’s on the clock! #Science #ClimateChange #Wildlife
