Weld County "Dump" Gulls/Severance

[The "Nunn Guy"]

Again this morning the Weld County "Dump" gulls were present on the dirt field basking in the brilliant morning sun at Weld CR 23 and 78 NE corner.  I saw Ring-billed, California and Herring gulls.  The gulls are very near edge of Weld CR 78 road.  These photos are 20x optical zoom.  It took 10 photos to get the entire flock at that zoom. 

See if you can ID more here, let me know:  http://coloradobirder.ning.com/photo.  Lower right of each photo is "Click Full Size". 

Thanks Gary Lefko, Nunn
