Subject: [obol] Re: Song Sparrow subspecies in Oregon
No offense to Gabrielson & Jewett, as they have contributed an amazing amount
of knowledge to Oregon birding, but I suspect that geographic ranges have been
fine-tuned within the last 60 years by genetic analysis.

As has already been put forth, Birds of North America (BNA) has a great write
up on each species, including Song Sparrow. The eBird excel spreadsheet that I
have mentioned in previous emails also elucidates ranges.
