RE: [CALBIRDS] Possible Mongolian Gull (Larus mongolicus) in Petaluma 8-9 March
- Just a thought on this one... Could it possibly be a cross between a
Glaucus-winged and Glaucus gull???

1) When you see mongolicus and vega in the field i.e. in ASia, you slap your forhead, and exclaim, "Man, they're obvious!" In other words, if you're looking at a gull here that just strikes you as being so different from smithonianus, et al, run with it.
2) The Chinese (and who else?) consider what we call races of Herring Gull to be several species. They called one Mongolian Gull. I think the BRits have joined in on Armenian Gull. That's off the top of my head, without pulling the Chinese book off the shelf...
