Sat AM birding

My dad and I got out for a couple hours this morning, hitting Mojeska Canyon, situated in the Santa Ana Mountains, and parts of the Santa Ana River. Mojeska Canyon is mostly chaparral and oak riparian. Best bird there for me was a single Rufous-crowned Sparrow, along with the common residents of the named habitats - Band-tailed Pigeon, White-breasted Nuthatch, Acorn Woodpecker, Oak Titmouse, Western Scrub-Jay, etc. We also birded the Santa Ana River, looking for shorebirds, but found few despite a good amount of mudflats - I had (25) Western Sandpiper, (5) Least Sandpiper, (3) Greater Yellowlegs and (1) Short-billed Dowitcher. Pretty depressing! Other birds of note were (2) Orange Bishops and lots of egrets and herons... here's a mediocre shot of an adult Black-crowned Night-Heron... nice plumes, eh?
