Dave, I don't know where the cutoff is between interior and full
black-eared. The "ear" came out brown on your picture...I would throw out a
guess that this bird is 80% of the way towards a black-eared. I await the
comments of the master of molt, Tony Leukering, on this one. I only know,
roughly, that 1) black-eared used to be a separate species, and 2) Sibley
speaks of this coloration as being noted in immatures. I have never handled
specimens, much less with this question in mind.
