BRIDLED TITMOUSE: Baeol6phus w611weberi annexus (Cassin) 
Description. — Length: 4.5-5 inches, wing 2.6-2.S, tail 2.4-2.6. Adults: Crown 
deep gray , crest , and back of head black , sides of head white , marked or bridled with 
black; rest of upperparts plain grayish; throat black , median underparts grayish 
white, becoming olive-buffy posteriorly (less or wanting 
in summer). Young: Chin blackish but throat grayish, 
and bridling less sharply defined. 
Range. —Apparently resident. Breeds mainly in 
mountains of Upper Sonoran Zone of southern Arizona 
and southwestern New Mexico south over the highlands 
of Mexico to Sonora and Chihuahua. 
State Records. —The southwestern part of New 
Mexico is the northeastern limit of the range of the Bridled 
Titmouse; it has been found here in the San Luis Moun¬ 
tains (Mearns); among the oaks of the basal slopes of the 
Animas Mountains, 5,500-6,500 feet, and on the northeast 
slope of the Burro Mountains, 6,000-7,000 feet (Goldman); 
at Silver City (Marsh); Pinos Altos Mountains (Fisher); 
Fort Webster, once, May 10, 1853 (Henry); [several were 
seen on June 21, 1926, 4 miles west of Cloverdale, Hidalgo County (Ligon)]; Gila 
(Goldman); Glenwood (Bailey); Cooney (Barrell); and north to the San Francisco 
Canyon above Alma, where two small flocks were seen October 14, 1906 (Bailey). 
The species is non-migratory.—W. W. Cooke. 
Nest. —In cavities of oaks, lined with soft materials. Eggs: 5 to 7, plain white. 
General Habits.— The sharp-pointed black crest and the black 
throat and face markings of the Bridled Titmouse, besides lending it 
charm and distinction, may well be a family convenience in the dull- 
colored oaks where other dull-colored titmice disport themselves. 
Small flocks of about half a dozen each, probably families, were eagerly 
met with among the blue oaks, junipers, and nut pines of San Francisco 
Canyon, where they were associated with Lead-colored Bush-Tits and 
Gray Titmice. Other small flocks of the prettily marked Bridled were 
later discovered in sycamores in the open valley, at the junction of 
White Water Creek and San Francisco River; but they are more 
characteristically birds of the oak country. In the Huachuca Moun¬ 
tains of Arizona, Mr. Swarth has found them abundant in the oak 
regions, late in August, going about in flocks of twenty or twenty-five 
birds (1904, p. 62). 
Active, sprightly little bodies, they go flitting . about the trees 
singing a song easily recognized by its chickadee inflections, though 
thin and tinkling—at least in November. One that I watched hopped 
up the branches of a tree quite in the manner of a jay climbing his 
tree ladder.
