Yellow face and head, grey body, curved bill; probably a female Bullock's Oriole but I didn't get a good enough look to be sure.
Most of them in flocks, sewing machining away in the shallow water.
Mostly in pairs.
Under one of the bridges (the two other bridges I went over had cliff swallows instead)
Could see white face through binoculars, these were quite close to my car.
Never looked away the whole time I was parked here. S/he laid down after a while, but still kept eyes and ears trained on me.
A few around.
Young ones with stripey heads.
1, leaping awkwardly from one bush to the next.
1. Good look through binoculars.
Only saw a scattering of males, mostly solitary.
