Resident in forests of pine ; hence so far as known confined to the 

 hills of the interior. 



As one wanders through the beautiful pine forests of the high- 

 lands of Hispaniola, there comes suddenly to the ear a low, trilling 

 song that to the uninitiated might be merely the stridulation of some 

 insect but that in fact gives notice of the presence of the pine warbler. 

 Gazing aloft, after careful watching the bird may be seen working 

 actively among the branches at such an elevation above the ground 

 that there is perceived merely a glint of the yellow breast. When 

 familiar with the species and its habits one comes to expect its calls 

 wherever pines are encountered though there may be only two or 

 three scattered trees on an otherwise open slope. The birds are 

 most common in the great stands of pine on the interior of the 

 Dominican Republic. 



The pine warbler was first recorded by Cory who secured several 

 young birds near La Vega, in July, 1883, indicating that the species 

 nested on the island. It was reported by Verrill as common in the 

 pine forests, apparently in this same region, as this traveler entered 

 the region of pines only at La Vega and Miranda. Abbott found it 

 common in the pine forests at El Rio and Constanza, collecting his 

 first specimen, a male, at Constanza on September 24, 1916, and others 

 on April 11 and 29, 1919. At El Rio he collected three on May 13 and 

 15, 1919, noting that a female taken on the latter date contained 

 a nearly formed egg. R. H. Beck found it in 1917 on Loma Tina 

 and Loma Rucilla. 



In 1927 Wetmore heard the songs of the pine warbler on May 18 

 as soon as he had entered the pine forests above La Vega and observed 

 the birds frequently in suitable localities on the trail to Constanza. 

 The species was fairly common at the latter point so that nine were 

 prepared as skins between May 19 and 27. Often the birds were 

 difficult to locate as they frequently ranged twenty meters from the 

 ground among limbs that moved constantly in the wind. Occasion-
