Observation details

Originally entered with these notes: "presumably Cistothorus platensis graminicola, with Clements range statement "Andes of s Peru (Junín to Cusco) to nw Bolivia", but then corrected to sssp. aequatorialis after feedback from Andre Moncrieff (thanks!) who wrote "The HBW range description for this taxon is "S end of C Andes of Colombia S to C Peru (S to C Junín)", which includes the Huánuco Department. I just checked in the LSU collection and the differences between C. p. aequatorialis and C. p. graminicola are very subtle--plainer crown and more limited back streaks in C. p. aequatorialis. It's hard to tell for sure, but your photos are at least consistent with the expected taxon: C. p. aequatorialis." Thus, I clearly misinterpreted the range. Note that the photos show the plain nape and plain scapulars illustrated in HBW which seem to be the same traits that Andre notes and that separate it from graminicola. heard singing (more House Wren like song) and scolding (harsh chattery notes completely unlike northern birds) in thick swale near lake and two others heard giving harsh scold; later seen and photographed at close range: large, quite long-tailed, very buffy, and with muted Sedge Wren pattern; almost recalls Bewick's in size, tail length, and song. Photos in dense fog, with significant adjustment in iPhoto.
