Perhaps this Glossy Ibis arrived with the monsoonal flow out of the Caribbean last week, as they are common to the East Coast. Often referred to as Black Curlews, they are shaped differently than our plumper and partridge-like Long Billed Curlews and behave more like Great Egrets and Blue Herons as shallow wading birds, though smaller than both. Try as I might to record this sighting with ebird, I failed. What distribution maps I found indicate no sightings in Central California. Amazing what you see when irrigating!
(Spooked a bullfrog!)
