Very interested in various reports from Front Range and elsewhere
I have a bit of a theory about why the Plains have been so devoid of common migrants this fall.
The mountains have been lush.
Usually our mountains are arid in fall, and therefore, relatively devoid of buggy forage.
However, this year has been quite different.
So, fewer birds wander out onto the lowlands.
Additionally, the Plains have been lush. Everywhere is green. So, the birds that are on the Plains are also more dispersed. Kind of a double whammy against finding passerines on the Plains this fall.
Neenoshe (Kiowa County) has been rather good for migrants during my couple visits, and I think that is because it is in the driest part of the state and isolated from anything resembling trees.
These foggy, drizzly days are accompanied by even colder and more dreary weather in the mountains, so on those days, Wilson's Warblers and such move into the Front Range foothills and adjacent plains in big numbers, perhaps a bit locally, thus explaining some of the recent fine concentrations that Ted Floyd, myself and others have found during those types of days during the last couple weeks. This effect seems to extend, to some degree, out to Crow Valley but not farther east.
Good Birding
