THE BIRDS OF NEW JERSEY. 281 



Adult female. Much browner above and paler beneath, often without a trace 

 of yellow. 



Young in first summer. Brown above, drab beneath, somewhat mottled with 

 dark gray ; center of abdomen, whitish ; wing and tail feathers as in the adult. 



Nest of strips of bark, leaves, etc., in a pine tree, twenty or thirty feet up; 

 eggs, four to five, grayish-white, with a ring of brown spots at the larger end, 

 .68x.52. 



Common summer resident in the pine barrens; elsewhere a rare 

 transient. Arrives March 30th, departs October 5th. 



The Pine Warbler is one of the most characteristic birds of the 

 pine barrens of the southern part of the State. It is deliberate in its 

 movements, slowly exploring the thick bunches of pine needles or oc- 

 casionally clinging to the trunk of the tree in pursuit of insects. 



In plumage it is one of the plainest of our Warblers. Its song is 

 a clear trill, closely resembling that of the Chipping Sparrow. 



While undoubtedly nesting abundantly all through the pines, the 

 nest is exceedingly hard to find, and, so far as I am aware, the only 

 ones found recently were one discovered by Mr. R. T. Moore, near 

 Tuckahoe, 1 May 13th, 1908, and two found by Mr. H. H. Hann, at 

 Chatsworth, May 28th and June 1st, 1904. 1 



At High Knob, Sussex county, Mr. F. M. Chapman found a colony 

 of these birds, June 10th, 1890, and secured a young one, which is 

 the only evidence of their nesting outside of the barrens. At Engle- 

 wood he had seen it but twice. 2 



Mr. S. N. Rhoads saw one at Haddonfield, on January 30th, 1898, 

 and possibly a few may winter regularly among the pines. 3 



672 Dendroica palmarum (Gmelin). 

 Palm Warbler. 



Similar to the next in general appearance but much paler, with yellow 

 largely replaced by white and size smaller. Length, 4.50-5.50. Wing, 2.50. 



Rare transient visitant ; the bulk of the migration taking place west 

 of the Alleghanies. 



One was taken at Princeton, October, 1877, by Mr. W. E. D. Scott : 4
