Do anybody have a correct species for this winter bird in our back yard?
If it were in my back yard here in Colorado I would think it is a male House Finch of the red variation, although a Cassins Finch is similar but it lacks the brown cap on the head of the House Finch. We see lots of House Finchs in the Colorado Mountains but not many Cassins where I live.
I'd go with purple finch as the species, but as far as the name is concerned, it looks kind of like Arnold. He shows up around our place in CT occasionally.
Photograph and/or see these daily in SE PA... male House Finch. Immature males occasionally have light orange or yellow-orange tinge before they molt to red coloration with the brown striping in the abdomen and sides.
