For me what makes the kinglets so stunning is the modest plumage with a dramatic flash of color when they get their dander up. That and the fact that when I was about seven and we were camping up in the Porkies on the UP when a Golden Crowned decided to use my head and shoulders as a launching pad to hawk gnats and blackflies swirling around my head, I’ve been entranced ever since.
