Today at my feeder I had
3 Stellars Jays,
over a dozen Oregon Junkos,
several American Robins,
a couple of Northern Flickers,
many house sparrows,
and a couple of striped little sparrow-like birds I haven’t identified yet.
I use an air gun to tweak the tails of any kittehz that try to interrupt the feathered ones. Squirrels get headshots, though.
My hunch is that your unidentified striped sparrow is a white-crowned sparrow.
This time of year, hundreds of thousands of them overwinter throughout the western states.
