Detalhes da observação
Song is "non-local" buzzier 4 part whistle-trill-trill-buzz (Baptista) @ 0:01, 0:29, 0:49 & 1:03 with long primary projection (However, Pyle 2022 puts nutalli & pugetensis pp5-9 as overlapping and perhaps even longer in nutalli!). Additionally, these are the individuals with a pale clay background to their mantle, paler overall (versus brown and darker in nutalli), similarly described as pugetensis by Dave Irons and Don Roberson. Similar individuals seen at Heron's Head & Yosemite Slough. Examples of Washington birds labeled as pugetensis & Summer California birds labeled as nutalli The SY with incomplete crown molt is interesting as it proceeds differently than nutalli, will try to add more photos.
