WARBLERS: BLACK-THROATED GRAY WARBLER 623 
From Handbook (Fuertes) 
Fig. 108. Black-throated 
Gray Warbler 
brownish gray, a wide white stripe back of eye, anterior underparts gray, breast 
lightly streaked, belly white. 
Comparisons. —The general gray color, black or black and white throat and 
absence of yellow, except for the one spot in front of the eye, are diagnostic. 
Range. —Breeds in high upper Sonoran and lower 
Transition Zones from southwestern British Columbia, 
Nevada, northern Utah, and western Colorado south to 
northern New Mexico, southern Arizona, and north¬ 
western Lower California; winters from Durango to Vera 
Cruz and Oaxaca. 
State Records. —[There seem to be only two nests 
recorded for the Black-throated Gray Warbler in New 
Mexico, May 22, 1920, and June 11, 1922, near Arroyo 
Hondo, about 6 miles southeast of Santa Fe (Jensen).] 
At Santa Fe in June, 1874, several adult males were seen 
and a specimen was taken on June 16, in worn plumage as though breeding, though 
no nests could be found nor were any females seen (Iienshaw). Old birds were 
noted feeding full grown young in July, 1907, in the Chuska Mountains (Gilman); 
and they breed near by in both Arizona and Colorado. 
One was seen and collected on July 3, 1903, near Pecos, 7,000 feet (Bailey); 
one adult male, early in July, 1892, at Fort Wingate, 7,000 feet, and Pinos Altos 
Mountains, 8,000 feet, July 8, 1894 (Fisher); San Pedro, July 9, 1889 (Bailey); 
San Luis Mountains, July 5-19, 1S92 (Meams). These last are very suggestive 
dates; five specimens were taken in July, and none earlier, though two persons had 
been making large collections in this district since the middle of April. Two were 
seen and one collected July 18, 1903, in the Capitan Mountains (Gaut); one at Carls¬ 
bad August 5, 1910 (Dearborn); they were fairly common August 6-8, 1908, in the 
Animas Mountains from 5,800 feet to the summit (Birdseye); young of the year 
were seen in August at Shiprock, 5,500 feet (Gilman); and one seen September 
12, 1909, at 8,500 feet, near Monica Spring in the San Mateo Mountains (Goldman). 
In the spring migration, the species was noted at Fort Bayard (Rockhill); once 
at Apache (Anthony); [one taken May 8,1920, in the Animas Mountains, where they 
were common (Ligon)]; one taken May 10, at Fort Webster (Henry); they arrived 
April 7, 1884, at Silver City, and remained until May 12 (Marsh); also at the same 
place they were seen in migration, during April and May of 1904 and 1905 (Hunn); 
they arrived at Cooney April 6, 1889, and at Carlisle April 9, 1890 (Barrell); but did 
not remain to breed at either place.—W. W. Cooke. 
A Warbler described from New Mexico by Doctor Henry as Sylvicola nigricans 
proves to be the same as Dendroica nigrescens. 
Nest. —Low down in dense thickets of scrub oak or high up in pines; compact, 
deeply cui>-shaped, made sometimes of grass, weed stalks, moss, and feathers, lined 
with feathers, horse, cow, and rabbit hair or fur. Eggs: Usually 4, white to pale 
greenish white, delicately spotted with reddish brown, purplish, and under shell 
marks of pale lavender, mainly about the larger end. 
Food.— Partly small green caterpillars. 
General Habits. —The descriptively named Black-throated Gray 
Warbler is one of the attractive birds found in New Mexico and 
Arizona in the oak and pinyon pine country, where its simple, soothing 
zee-ee-zee-ee, ze, ze , ze makes one wish for better acquaintance. A 
pair that were watched by Mr. Bowles became so tame that while he
