8-14-16 correction--I stated below that landbird migration had begun but this was corrected by the following post on Cobirds listserv by Tony Leukering: <<< "While I typically like SeEtta's posts and blog, I have to disagree with her assessment of "landbird migration." Chipping Sparrows have been moving for more than a month, while Yellow Warblers, Lark Buntings, Bullock's Orioles, and an additional unknown number of Colorado-breeding species (but probably including all of the so-called "monsoon migrants"; see first link, below) have been on the move for 2-3 weeks (if not longer), now. As example, Lark Bunting does not breed in Arizona, yet migrants begin arriving -- even in southern Arizona, in late July, suggesting that migration was initiated sometime before then (see second link, below). http://www.bioone.org/doi/abs/10.1525/cond.2009.090085?journalCode=cond http://ebird.org/ebird/GuideMe?cmd=decisionPage&speciesCodes=larbun&g
