Nest was found on 20 Mile Rd parking lot for HCNC on May 17, 2012 by Phil Chu, at which time it contained 2 nestlings within days of fledging. Birds today were out of the nest and approximately 300m to the NE in a private woodlot calling constantly and begging for food. Today I witnessed 1 feeding event where an adult came in and fed 2 different birds. I never actually saw the 2nd juvenile, but inferred its present by simultaneously watching the 1st bird's bill produce about half the calls I was hearing. The 2nd bird, which didn't leave the woodlot to forage and also begged when the adult came in (thus not an adult) was farther back in the woodlot. It sounded identical to the bird in the pics and vids. Finally, a 3rd raven was heard behind the 2 juveniles, calling more intermittently, may have been an adult or juvenile.
