“They go to all the same places, they know where they’re going to get certain species,” she said.

The two birders will be easily identifiable by the equipment they carry and their tendency to pull over to the side of the road and start “spotting.”

“They’ll be in a car driving around, you might see them pull out their spotting scopes and tripods — especially to look for shore birds and ducks way out on the water,” Packett said.

Weather and bird migration patterns will determine the birders’ deployment, Packett said. Dry weather combined with populous migratory activity in the skies above Wisconsin this time of year make for the perfect weather to spot species of numerous varieties.

“Billions and billions of birds take flight every evening in the spring and fall” across the continent, she noted. “If you check weather radar, you will see this enormous bloom over any city. It’s like polka dots all over the Eastern U.S.”
