I know there has been a technical article on these recently. But these simple photos clear up the question I had about minima, taverneri, and parvipes in the Willamette Valley.

I now see that Taverner’s Cackling is significantly larger than minima Cackling. I had been seeing flocks of minima with a lot of variation on breast color and confusing myself.

The wing length and neck thickness examples were appreciated field marks to help me separate Taverner’s from Lesser.

This article let me easily identify a recent bird as Taverner’s:
