From a distance, I thought the bush was covered with butterflies. But, they turned out to be Ruby-crowned Kinglets, tiny birds even smaller than chickadees.
These frenetic birds were difficult to photograph as they hardly ever stopped moving.
Only males show the ruby crown, and even for them it is usually hidden.
Oh the roundnesses. I would never have been able, otherwise, to see one so close. You certainly have a capacity for capturing the pose.
