This seems to have been a good season for Yellow-billeds. Compared to status ca. 1992, I think the great increase in the number of birders, existence and remarkable growth of eBird, improved communication speeds (often in real time) and prevalence of so many, many more cameras and photos to help confirm IDs are probably factors to consider in assessing changes.

Hi All
In 1992 with the publication o Colorado Birds, the Yellow-billed Loon was considered a casual fall migrant (5 records) and winter resident (4 records). According to this winter's eBird reports there has been multiple sightings, at multiple reservoirs. Something is going on with the Yellow-billed Loon. Could they be having more successful breeding in the arctic (if so why) thus significantly more YBLO are moving south in the winter? Usually there isn't just one reason to explain phenomenon, but multiply inter-connected reasons.
Anyone have any ideas!
