In the past, barn swallows have benefited from human changes to natural landscapes. As humans destroyed vast areas of forest to convert to farmland, they created large areas of new habitat for swallows. Now, as farming is becoming more modernized, barn swallows may be becoming less abundant. Barns and hay lofts are now becoming enclosed, resulting in fewer places for barn swallows to build their nests. However, barn swallows continue to be widespread and common throughout their range. There are about 190,000,000 barn swallows in the world.
