On September and October nights, nearly 300,000 birds are flying south over Howard County, Maryland. Birds begin to migrate about 30 minutes after sunset, sometimes up to 10,000 feet up in the air. But it helps if you point outside lights down, or better yet, turn them off, to avoid muddling the birds' migration. Cornell Lab's BirdCast uses radar to detect the birds, and using birders' spotting information, reports that the most common migrators at this time of year are Eastern peewees, yellow-bellied sapsuckers, white-eyed vireos, wood thrushes and so many warblers!
