HABITS. The Black and White Creeper, nowhere an abundant species, is met with in various sections of the country. It occurs in all parts of New England and New York, and has been found in the interior as far north as Fort Simpson. It has been met with on the Pacific coast only at Mazatlan, is common in the Bahamas and most of the West India Islands, generally as a migrant. It has also been found in Texas, in the Indian Territory, and in Mexico, and throughout Central America. In the last-named region Mr. Salvin states it to be pretty equally and generally spread over the whole country. It is there migratory, leaving in spring. It was also detected in Colombia, South America, by Mr. C. W. Wyatt. Mr. Newton also met with it as a winter visitant in St. Croix, leaving that island at the end of March. He regards this species as almost a thorough Creeper in habits. In Jamaica a few are resident throughout the year, according to the observations of Mr. March, and though its nests have never been found there, a son of Mr. March saw a pair carrying materials with which to construct one. Dr. Coues states that this Warbler is a very common summer resident near Washington, but is more abundant there in the spring and in the fall, the greater number going farther north to breed. They arrive in Washington during the first week in April, and are exceedingly numerous until May. He adds that they are generally found in high open woods, and that they “breed in holes in trees.” This is probably an error, or, if ever known to occur, an entirely exceptional case. Our bird is also a common summer visitant at Calais, arriving there about the 1st of May, and by the 10th becoming rather abundant. Mr. Boardman has frequently found their nests there, and always on the ground, in rocky places and usually under small trees. It does not appear to have been met with on the Pacific coast north of Mazatlan, nor in any portion of Western North America, beyond the valleys of the Mississippi and the Rio Grande. In its habits this bird seems to be more of a Creeper than a Warbler. It is an expert and nimble climber, and rarely, if ever, perches on the branch of a tree or shrub. In the manner of the smaller Woodpeckers, the Creepers, Nuthatches, and Titmice, it moves rapidly around the trunks and larger limbs of the trees of the forest in search of small insects and their larvæ. It is graceful and rapid in movement, and is often so intent upon its hunt as to be unmindful of the near presence of man. It is found chiefly in thickets, but this is probably owing to the fact that there its food is principally to be obtained. It is occasionally seen in more open country, and has been known to breed in the immediate vicinity of a dwelling.
