In its general appearance and in all its habits it is mentioned as having so close a resemblance to the common Tufted Titmouse as to be hardly distinguishable from that bird. Dr. Woodhouse met with this species near San Antonio, Texas, in March, 1851. While his party was encamped on the Rio Salado he observed these birds busily engaged in capturing insects among the trees on the banks of the stream. Like all the members of this family, it was incessantly in motion and very noisy. Later in the season, on the 8th of May, the same party, when encamped on the Quihi, again found this species very abundant among the oaks. The young males, then fully grown, closely resembled the adult females, both wanting the black crest that distinguishes the mature male. He afterward noticed this species occurring at intervals along his route as far as the head waters of the Rio San Francisco in New Mexico. He observed it almost exclusively among the trees that bordered streams of water. The females and the young males invariably had crests of the same cinereous color as their general plumage, but in the latter slightly tinged with brown. They occurred in small parties, were very lively and sociable in their habits, and in their general appearance and even in their notes so very closely resembled the Eastern species as, at a short distance, to be hardly distinguishable from it. Dr. Heermann, in his report on the birds of Lieutenant Parke’s survey, mentions having first observed this species near Fort Clarke, in Texas, where it was very abundant. He describes it as sprightly and active in its movements, searching with great assiduity for insects in the crevices of the bark and among the branches of trees. While thus engaged it keeps up a chattering note, varied with an occasional low and plaintive whistle. Its habits appeared to him to resemble most those of the common _Parus atricapillus_. Dr. Heermann states that it builds its nest in the hollow of trees, and that it lays from twelve to sixteen eggs. He does not, however, say that he ever met with its eggs, nor does he give any description of them. The nest, he states, is composed of fine dry grasses, feathers, wool, mosses, etc. General Couch’s description of this species and its habits is very similar. He observed it in the province of New Leon, in Mexico, where he found it very abundant along the San Juan into the Sierra Madre. He describes it as a very lively bird, with a very perfect whistle of a single note. Mr. Henry A. Dresser sought very diligently for its nest and eggs near San Antonio and Houston, in Texas, where he found the bird very common, and where he was sure many pairs remained to breed, but its nest was very hard to find, and the birds very wary. He succeeded in finding one nest, in a hollow tree, near the head springs of the San Antonio River, but it contained young. The nest he does not describe, nor does he mention the number of young it contained. Lophophanes inornatus, CASSIN.
