These are two different birds, shot on different days, at different locations under drastically different lighting conditions. But I'm having a hard time deciding if they are different species. 1. This one was taken in morning light. Randy, Micheal and I thought it was a juvenile Yellow-crowned Night-heron. This one, taken in evening, appears to be a juvenile Black-crowned Night-heron. It's so hard to tell with juveniles - so I thought I'd ask the experts here. Do I have it right?
