[obol] Nashville Warblers everyone?

[Dennis P. Vroman]

High elevations is where a lot of Warbler (especially fledglings of the year) are in the fall.  When you think about it, it makes sense.  They concentrate around wet meadow/brushy areas at high elevations, for...this is where the "bugs" are.  Have seen mixed species flocks (Warblers, Flycatcher, Buntings, so on) of 40+ birds at such locations (once captured 160+ birds as such a location in one day).  Most all valley locations are dry in the fall and insect populations are low.  One exception is the lush, wide river riparian locations, such as along the Rogue/Applegate Rivers.

An interesting side note, the fall exodus of Nashvilles occurs almost exclusively at high elevations.  Southbound Nashvilles are quite rare at low elevations and there seems to be no post-breeding dispersal into the valleys of western Oregon.

    Oboler’s,

    I don’t know about “the valley” but in the Bear Creek/Rogue Valley area the numbers of warblers, including Nashville have been amazing. Countless numbers of Yellow-rumps much beyond past years. Orange-crowned warblers and Nashvilles have vastly exceeded what is normally seen at this time of year. At first it was thought it might be the weather pattern causing them to hold in this valley but with nicer weather the numbers have increased. But the most noticeable warbler has been Wilson’s. Where we normally see one or two or none we are literally seeing them by the dozen. The number of Common yellowthroats has been very high also but it appears their numbers have tapered off this week. This week vireos in larger numbers than usual have started to appear.



    It has been fun to see.

    Maybe I haven't been paying attention in past years, but it seems to me we are hearing more than the usual number of spring reports of Nashville Warblers in "the valley" this year.  I've had two in the past two days here in McMinnville's Airport Park.  Anyone else thinking similar thoughts?
