The guide is available at the Edmond Library and includes a checklist of common to extremely rare birds that can be encountered in Mitch Park.
Jeff Hall said his wife has identified more than 200 birds in the park.
“There are 26 winter species in Mitch Park and 27 that are pretty much here year-round,” Susy Hall said. “Then it goes up to 31 in summer.”
Birding, Susy Hall said, is the best hobby she can imagine.
“It gets you outside, gets you exercise. Every day is different, every walk is different. Sometimes you get a treat — a bird or behavior you haven't seen before,” she said.
The Halls offer advice to anyone thinking about getting a start in bird-watching: Start at home. Set up a bird feeder and possibly a birdbath in your backyard.
“The best place to start is a place where you can constantly see birds — your backyard,” she said.
“They are there day after day, year after year.”
The Halls consider themselves birders, as opposed to bird-watchers who perhaps are more casual about the endeavor.
“There are zillions of bird-watchers,” Suzy Hall said, “but fewer birders.”
