MADISON, Wis. (AP) - Wisconsin wildlife officials are asking people to count and record chimney swift sightings.

The birds roost by the hundreds in brick chimneys as they prepare to migrate south to the Amazon River. They’re often seen streaming into chimneys like smoke in reverse.

The state Department of Natural Resources is asking people to keep their eye out for the birds around chimneys about 30 minutes before sunset through late September. The agency asks that observers try to estimate how many birds enter the chimney and report their observations on its website.
