Join a refuge representative at the Merced National Wildlife Refuge on Saturday, Feb. 21, at 4:45 p.m. for an interpretive event featuring the evening sandhill crane fly-in. This will be the final such event of the season since the sandhill cranes will leave for their northward migration by early March.

The presentation will include information about some of the remarkable physiological changes migrating birds undergo in preparation for their epic journeys. Participants will also learn about migratory birds considered to be some of the most incredible endurance athletes in the animal kingdom.

Meet at the main entrance parking area for the presentation. Afterwards, participants will watch the evening fly-in of the cranes as they return to refuge wetlands to roost for the night. The event should last 1 to 1 1/2 hours. There is no need to sign up.

For more information call the visitor center at 209-826-3508 or check out the refuge website at www.fws.gov/refuge/merced/events.
