Similar species and how
were they eliminated:
 I thought it would be just a Ruby crowned kinglet. But the beak wasn't black and much thicker and longer. The Beak was horn color and that is when I realized this was something better. My thoughts went to Huttons Vireo. The bird looks really good for Huttons. I submitted to Kenny and asked his thoughts..he said Huttons don't really migrate and someone else suggested Bay Breasted warbler.
Previous experience with
this & similar species:
 I have seen Huttons before in Arizona. I have kinglets at my bird feeders a lot. I have no experience with Bay Breasted.
References consulted: Kenny Frisch and my uncle Bruce Aird from California who is a very good birder.
