I thought I'd check Boulder Reservoir for jaegers this evening. There wasn't much action on the water at all, but flocks of bluebirds were everywhere. Most were Mountain Bluebirds, but along 51st St., SW of Sixmile Res. there was a group of 4-5 Western and possibly an Eastern. Surprisingly, these birds were flushed and pursued by an American Kestrel. I parked at the North lot where there were several dozen more MOBL and one EABL.
Not much else that I was able to turn up.
Good birding,
Peter
