All, As there's been a lot of birding at S Platte Res over the last couple weeks, I thought I'd make a couple comments about where the county line is and how to properly report birds in eBird.
See link below and zoom in on S Platte Res to see that the county line crosses the reservoir such that only the SW arm of the reservoir is in Jefferson Co. The majority of the reservoir is in Arapahoe Co. The county line does not run down the middle of the reservoir. http://maps.jeffco.us/ eBird: There is a hot spot for the SW Bay for reporting birds that occur on the Jeff Co side. And there's a hot spot for the Arapahoe side of the reservoir. Thanks Joe! ABA and reporting rules: In terms of the recent rarities, especially the Yellow-billed Loon, this bird has apparently only been on the east side of the reservoir and thus only in Arapahoe. As far as I can tell it hasn't ventured into the southwest corner. Thus reporting the bird in Jefferson Co is inappropriate, if it was not physically in that southwest corner. ABA rule: (1)The bird must have been within the prescribed area when encountered, and the encounter must have occurred within the prescribed time period. So standing in Jeff Co, seeing the loon in Arapahoe and reporting it in Jeff Co and/or reporting in both counties is inappropriate. Only reporting in Arapahoe is the way to go! If you reported the loon in Jeff Co, I'd encourage you to remove that report. Thanks!
