[obol] odd Mac Warbler song - Detroit Flats

[Norgren Family]

I had a similar experience last summer on
Johnson Road (Wash/Columbia Co, Hwy 47). While
pursuing a report of Dusky Flycatcher I heard
the weirdest Oporornis song. I was fairly confident
a Mourning Warbler was in my own neighborhood.
The bird obligingly flew up high above the brush
and sang from a fir bough over-hanging the road.
A completely typical MacGilvray's.   Lars Norgren
