Another important bird seed is niger. Adjustable adore niger. Niger is the black seeds, so small and lightweight that you can have a few blows with a soft sigh. Niger is also expensive, about one dollar per pound, so you do not want to waste. Buy a tube hanging with small holes, which is specifically designed to Niger, and hang it where you can see the window to see your best. Close to home, even under the roof, is fine. Thistle will be very tame and would not mind having two feet away from you, on the other side of the window while they eat.
Another favorite for bird safflower seed, white beans, slightly smaller than black sunflower seeds. Squirrels do not like it. Nor grackles, Blue Jays, or starlings. safflower seed is very bitter. Cardinals, titmice, chickadees, downy Woodpeckers, and chewed like candy, although there is always a good supply available on the platform feeder. The squirrels will not bother to go up there. White millet seed to attract other birds. It is even more expensive than sunflower seed. Sprinkle on the ground for sparrows, Juncos, and mourning doves.
