I saw these small finches at our thistle feeder, thinking, at first, they were female house finches, but then I noticed the yellow flashes on the wings. Pine Siskins are smaller with sharp, pointed bills and short, notched tails. Their uniquely shaped bill is more slender than that of most finches. Pine Siskins visit thistle or nyjer seed feeders in winter or cling to branch tips of pines and other conifers, sometimes hanging upside down to pick at seeds below them.
