Not only are hummingbirds inching closer to Illinois, but the great monarch butterfly migration is in full swing and they're also making some incredible progress toward the area.
Thanks to a map from Journey North, you can see where the monarchs currently are based on sightings reported by citizen scientists.
The latest data shows they've made it as far north as Tennessee, Arkansas and Oklahoma.
According to Journey North, the butterflies made significant progress last week thanks to strong winds that blew northward from Texas for five days.
Monarchs are known to glide on favorable wind conditions, and normally can fly at speeds up to 20 miles per hour. This allows them to travel anywhere from 40 to 100 miles per day during their predictable migration paths.
According to last year's map, the first monarch was spotted in the area on April 18.
