It includes information on such topics a monitoring nest boxes, predators and competitors, taking field notes, the feather study, the calcium study and other topics as well. Currently there is not enough scientific data to make a clear judgment on whether one should remove the old nesting material after the breeding season or leave it in the nest box. NatureCraft will provide information as it becomes available. Physical Description Adult Red-breasted Nuthatches have gray backs with rust colored beasts and undertail coverts. They have black caps and white eyebrows.
Females are less colorful, with a more washed-out rust color on the belly.
There are faint black edgings on the back, and the white on the eyebrow, chin, and sides of the head is speckled with black. The underparts are pinkish-buff, deepening the cinnamon on the crissum, the area around the doacal opening. Red-breasted Nuthatches inhabit northern and subalpine habitats. They are found in the southern half of Canada and in the western and northeastern regions of the United States. Ideal breeding habitat consists of mature, partly open coniferous or mixed coniferous-deciduous forests.
