Hi all - I thought I'd pass on the full eBird list from the weekly Wednesday walk at Nisqually Refuge.

The most 'exciting' bird was a late-October Empidonax flycatcher near the Twin Barns. Our views of it (no photos, dang it), and Nathanael Swecker's sonogram app led us to, initially, list it as a Pacific-slope. eBird reviewer Dave Slager correctly pointed out that, even with the sonogram, identification between the two "Western" flycatcher species is problematic - especially this time of year - and I revised the report to reflect that uncertainty.

Of course, the discussion of Pacific-slope versus Cordilleran flycatchers devolved into a discussion of "what constitutes a species?". I won't go any further down that slippery slope, lest I start my amateur pontificating on the American/Northwestern Crow debate....

Hope to see you at one of the weekly walks at Nisqually NWR. Refuge volunteers lead the walks beginning at 8 a.m. at the Visitors' Center every Wednesday.

Nathanael Swecker writes: Spectrum View of the Empid in question. After a . . . brief search for all vocalizations of Pacific-slope Flycatcher I have found two recordings that exactly match our bird. Based on the visual ID and the preliminary similarities in the spectrogram we should label this bird as a Pacific-slope Flycatcher.
