觀察細節

Two birds perched adjacent to one another calling with small, “chup” calls, like a cross between and Red-winged Blackbird call and a Yellow-rumped Warbler call. House sparrow shaped birds with pale stripes above and below the eye. One bird had a much more prominent yellow coloration to the breast while the other was quite drab and bedraggled. I’m assuming it will have to molt before migration as its feathers were not in great shape.
