Hi MD Osprey:
Here's something to peruse the snow storm ...

>This new portion deals with the difficult parvipes vs. taverneri id

>completed portion on B. h. hutchinsii as well as a now complete section on
>B. h. minima already posted on the site. Eventually all 11 subspecies

>will find the close-up picture of B.h. minima, B. h. hutchinsii, and B. c.
>parvipes together in the wild at Moses Lake, WA especially instructive.)

>This is a work in progress, and I do invite comments (and photos) as you
>may see fit to help us all better sort out this often thorny id challenge
>that has "magically" risen to the forefront since this summer's AOU "split
>decision"...while we continue to make everyone more aware of the wonderful
>world of the subspecies. I can definitely always use more close-up
>pictures of B. h. taverneri, B. h. leucopareia, and the larger Canada's,
>B. c. canadensis, B. c. interior, B. c. maxima, B. c. occidentalis, and B.
>c. fulva.
