The male House Finch can be identified by the red contrasts on its head with the brown cap and brown cheek patch. With a brown back and wings, the male has a red chin, throat and breast. The female House Finch does not have the red markings of the male, and is dull brown with broad streaks and white underparts in their chest area.
Almost any kind of feeder will attract House Finches, including hoppers, platforms, tubes and nyjer feeders. Their preference is nyjer seed, black oil and hulled sunflowers, but they will also eat nutrasaff and millet.
