The holes in a tube thistle seed feeder were drilled to 3/16" and a plate attached below to catch wasted seed.
The feeder was filled with a mixture of red and white millet and some available thistle seed.
It attracts mainly Indigo buntings. There is a sunflower seed feeder and a suet cake nearby. All are near some bushes.
The turquoise color of the male comes from the flash lighting.
