A great horned owl buzzes a crowd of spectators during a recent Raptor Free Flight demonstration at the Arizona-Sonora Desert Museum, 2021 N. Kinney Road. As the birds zip by just feet from spectators’ heads, volunteers give an amplified narration of the demonstration and explain facets of each species. The museum is open from 8:30 a.m. to 5 p.m. through February. Gates open an hour earlier in March. The demonstration is free with the price of admission.
