Swifts aren’t called ‘swifts’ for nothing. They’re known for being among the fastest migrating small birds around. When they aren’t breeding, common swifts stay in the air most of the time — up to 10 months of the year. Scientists had thought they travel about 500 kilometers per day on average. Now, new evidence shows that’s a conservative estimate.
