*Local rarity. Seen with Austin Parker (Palos Verdes Peninsula Land Conservancy biologist) during bird survey. Initially heard giving normal "ping-pong ball" ("Peep...peep..peep-peep-peep, etc.") song as we were walking down through the restoration area along the main path/"Burma Trail". Song was coming from high, dense growth of Artemisia calif. and Eriogonum fasciculatum that had been seeded and planted at the site (restoration started several years ago, but has only gotten lush and contiguous in the past 2 years or so). Bird sang three more times, and I was able to get a recording. It struck me as a fairly weak wrentit song w/o a lot of intro notes, which I associate with female birds in paired duets, but not positive of this. Later during the c. 10-minute observation, it delivered several (5?) "rattle" calls, which I'd describe as a dry, rapid "g-d-d"), and which sound like fingers along a comb. I know of no other CA species that has a vocalization anything like this, and I find it as distinctive as the whistle song. Walking by the area where the song came from, I glimpsed the bird flitting in the buckwheat and other vegetation. It was basically a dark, sparrow-sized "overgrown bushtit" with an exceptionally long tail. I started video-ing with my phone pointed in the direction of the movement and captured a bit of the movement and flight between bushes. I'll attach a couple blurry stills from this video. I noticed the warmer, more tawny brown color of the chest as it caught the light while it foraged, but otherwise it was entirely darker brown. I'm aware of the rarity of this observation and was astonished to hear it singing. I've conducted bird surveys at Portuguese bend since c. 2009 and have never detected it (nor have I recorded it anywhere else on the peninsula).
