As long as he doesn't touch the ground while he's on the wire I think he's okay. He has the same topknot and beak as our lady cardinals. Up high he can watch for his next meal so I understand him wanting to be there.
@laurieewilson They are lovely birds. I had the pleasure of them nesting in my jasmin. When they were not there I took a few pics of the siblings in the nest! Quite amazing
