This species has a yellowish brown crown and whitish underparts. Their habits are like those of the other Nuthatches, they nesting in cavities at varying heights, from two to fifty feet from the ground. That they sometimes depart from the usual custom is evidenced by the data accompanying this egg. They lay from four to seven eggs, white with profuse markings of reddish brown; size .60 × .48. Data.--St. Mary's, Ga. Nest situated under the bark of an old dead pine stump, 4 feet from the ground; made of fine strips of bark. 730.
