[birding] Re: Interesting Empidonax (Least?) Flycatcher at Luckiamute Landing, Polk Co.

[Joel Geier]

Thanks Maitreya,

Based on this information -- that hatch-year Hammond's can have a fully
orangeish lower mandible, there is no reason to rule out hatch-year
Hammond's Flycatcher based on what I observed. In fact, looking now at
Sibley's (big version) depictions of 1st winter Hammond's (& Dusky for
that matter) Flycatcher, the Cassin's Vireo-like color scheme of the
head is also there. Hammond's seems more likely for this site, and also
squares with that buzzy note that I first heard from the bird. 

Happy birding,
Joel
