Sennett's Warbler 



COMPSOTHLYPIS PITIAYUMI NIGRILORA (Coues) Plate VIII 



Distinguishing Characters. — Similar to Compsothlypis a. americana but 

 cheeks black; underparts yellow becoming white on the lower belly; breast 

 tinged with orange brown and without black; no white about eye; sides of 

 throat, at junction of yellow and black, with traces of white. Length (skin), 

 3.90; wing, 2.00; tail, 1.50; bill, .38. 



General Distribution. — Breeds in Northeastern Mexico and along 

 the lower Rio Grande in Texas. It winters in Mexico and has been 

 taken the last week of February, 1880, on the Rio Grande near 

 Hidalgo. 



The Bird and its Haunts. — At the time of its discovery by Mr. 

 Sennett in the Rio Grande Valley, this bird was supposed to be a 

 distinct species; it proves, however, to be the most northern repre- 

 sentative of a form of Parula Warbler which ranges over the greater 

 part of South America and northward through Central America and 

 Mexico to the lower Rio Grande. There it evidently resembles our 

 Southern Parula in habits, living, Merrill 3 says, "among thick woods 

 and near the edges of lagoons where there is Spanish moss." 



Nesting Site. — Merrill 2 found a nest near Brownsville, Texas, 

 eight feet from the ground in a bunch of Spanish "moss." Sennett 1 

 records one from Lomita, on the Rio Grande, which was placed in a 

 "mistletoe-like orchid" ten feet from the ground. 



Nest. — Merrill's nest evidently resembles that of the Parula 

 Warbler in the southern states, being constructed in the Spanish moss 

 and lined with a few horse-hairs. Sennett describes his nest as "con
