3 singing, 1 from E of the property early in the survey. Within 5 minutes of the survey start I saw a robin perched briefly on the sewage lagoon fence at the start point, then fly W. At 0655 a male flew back to the sewage lagoon fence near the start point and then began singing, at the same time as the individual E of the property along the creek. The near AMRO then flew to a Russian-olive 20 m E of the fence and sang some more. I was a bit surprised to see one so far out in the field - I don't remember observing that last year. At 0707 I saw 2 AMRO on the sewage lagoon fence, neither vocal at that point. At 0710 I saw a robin in the field near the start point briefly, likely foraging, and then it flew off. Sometime around 0815 an AMRO (one of these two singers?) was singing from a willow in the E part of reach 4. At 0926, 3 AMRO flew upstream over the diversion, loosely together, at roughly 5x shrub height. Later I saw at least 3 robins near the recently constructed wetland in reach 2, including 1 singing for a time from a Chokecherry S of the wetland, and 2 foraging on the ground. 1 was a female for sure (very pale gray-brown head). I saw the other catch and swallow a large worm (photo of the last bit of the worm in its beak). That individual was foraging on the stream terrace ca 5-10 m S of the stream in an area where equipment has been traveling, with bare disturbed earth and short, lawn-like green grasses. I presume that the individual singing here was different from those singing downstream. At 0959 all 3 robins took off and flew upstream. Then ca 1 minute later another robin flew up from downstream and perched in a Chokecherry, calling. Later, saw 1 individual singing near "WIFL flats." On the return I saw a robin near the stream on the puddled mud in the NE portion of the constructed wetland. It had a worm at its feet; it jabbed at the worm several times with its beak, picking it up partway. I also heard a robin singing for a while in this area on the return.
