Sitting atop the construction fencing that keeps small (crawling) critters out of the construction site, was a bird with flaming yellow plumage accented with black.
This striking fellow (and yes it is a male, the females are much more subdued in color) is a Bullock's oriole. The Alameda Watershed is home from spring through summer to Bullock’s orioles, like this first-year male. They'll winter in Mexico or Central America before migrating north again next spring.
They dine on insects, fruit, and raid the occasional humming bird feeder for the nectar.
See you around the Valley!
