The wolves are definitely tuned into the return of the public to the viewing windows at the Ely, Minnesota Interpretive Center.  In particular, Grayson’s predatory drive is stimulated by the sights and sounds of an active viewing window.  The wolves are generally more crepuscular with activity peaking around dawn and dusk, but with daily wolf care happening from 7:30 – 10, early morning visitors (to the facility or to the webcam), can usually catch wolf activity.  In order to provide some positive stimuli to the wolves, staff also conduct enrichment programs at 12 pm, 2 pm and 4:15 pm that vary between frozen treats, scents, feathers and even some bear bedding from the North American Bear Center, also located in Ely on the west edge of town.
