Join licensed biologists as you study aging, migration patterns and assess populations of wild birds with a morning of bird banding. The event includes demonstrations of how wild birds are safely captured, banded and released back into the wild. Make sure to bring your camera, as there will be some great up-close time with the songbirds. All ages, children 17 and under must be accompanied by an adult. Free admission. Saturday, 9–12 a.m. Eastman Nature Center, 13351 Elm Creek Rd.; 763.694.7700; threeriversparks.org.
