THE OOLOGISl. 



where the foliage is farther advanced 

 and the buildings offer some protec- 

 tion from the storm. The Blackbur- 

 nian is one of the warblers frequent- 

 ly seen at such times, and as they 

 keep low down, they often attract the 

 attention and arouse the curiosity of 

 persons who at other times would 

 never notice them. 



After the migrations are over with, 

 a few pairs are found in the mountains 

 as summer residents. They are not 

 common, but the song of the male can 

 be heard almost any time in the right 

 sort of woods. 



They seem to prefer heavy wood- 

 land in this region where there is a 

 large amount of hemlock. The birds 

 in summer keep high up in the trees 

 and it is a hard matter to see one when 

 the song comes floating down. Owing 

 to the fact that I have had poor suc- 

 cess finding nests, I think this warbler 

 must usually nest high up like the 

 Black throated Green Warbler, which 

 is a rather common summer resident 

 in the same forests. 



So far, only two nests have come un- 

 der my observation. The first was 

 found in early July, 1901. It was thir- 

 ty feet up and five feet from the trunk 

 on a horizontal limb. It held four 

 large young. 



The second I found June 23d, 1907, 

 in a heavily wooded hollow in the 

 mountains in a large tract of mostly 

 virgin forest. This nest was twenty 

 feet up and five feet from the trunk 

 on the horizontal limb of a small hem- 

 lock. When I saw this nest the owner 

 was not about. Climbing up I found 

 four eggs. It had much the appear- 

 ance of a magnolia's, but still didn't 

 look right, so I returned several days 

 later and found a female Blackbur- 

 nian at home. 



Both nests were built of five hem- 

 lock twigs and were flatter than the 

 magnolia's. The set of four was heav- 



ily blotched and spotted usually well 

 marked as compared with several sets 

 I have seen in collections. 



In the fall I have seen it here as 

 late as October 8th.

Nesting of the Blackburnian Warbler. 



The Pocono Mountains of Pennsyl- 

 vania still preserve a fauna decidedly 

 Canadian. Here are found the Olive- 

 sided Flycatcher, White-throated Spar- 

 row, Pileated Woodpecker, Yellow- 

 bellied Sapsucker, Golden-crowned 

 Kinglet, Winter Wren, Hermit and 

 Olive-backed Thrushes. But the great 

 wealth of bird-life is brought out most 

 strongly in the number of breeding 

 warblers. Of these the most interest- 

 ing are the Magnolia, the Chestnut- 

 sided, the Pine, the Black, the Green, 

 the Blue, the Canadian, the Nashville, 

 and the Blackburnian. 



The last named species is not rare. 

 In all spots where a growth of vir- 

 gin hemlock is to be found this bird 

 occurs. But flnding the bird and find- 

 ing the nest are two widely separated 

 stages in the tyro's studies of the 

 Blackburnian Warbler. 



Seven o'clock on the morning of 

 June 17th, 1909, found me at the edge 

 of what is locally known as the "Prim- 

 eval Forest" in Pike County. In front 

 of me the sun was well up over the 

 barren hills which had been left by.
