44. Yellow=throated Vireo Vireo Jlavifrons. I have 

 twice discovered the nest and three epgs of a single 

 pair which yearly haunt the larger swampy thicket. 2 



45. White=eyed Vireo yireo noveboracensis . A pair in 

 either of the swampy thickets. Perhaps not so well 

 represented as it should be. 4 



46. Black and White Warbler Mnioii/ta varici . So con- 

 spicuous as a transient, it is wonderful how invisible 

 it becomes as a housekeeper. It inhabits the rocky 

 hillsides where the trailing arbutus and laurel grow 

 under the trees, and extends down to the damp 

 thickets of the bottomlands. When the young are 

 well along, it is familiar enough. My enumerations 

 were made principally from the singing males, with 

 later family groups as corroborative evidence. Eight 



to twelve pairs. 20 



47. Wornt'-eating Warbler Helmit/ierusvermh'onis. Per- 

 haps as common here as anywhere else in the country 

 as a summer resident. It loves the steep wooded hill- 

 sides and ravine slopes above the running brooklets, 

 building its nest under a drift of withered leaves which 

 have lodged against a laurel sprout, wild huckberry 

 spray, sapling or a dead stick; though it is only less 

 common on the gentle slopes where conditions are 

 suitable. 1 know of no other ground-nesting Warbler 

 that gives greater delight to the eye than this trim, 

 slender and graceful little member as it dodges nimbly 

 above and about the fallen leaves, or sits so bravely 

 and defiantly in its snug cave-like dwelling, calmly 

 eyeing the intruder; doubtless trusting to the last 

 minute in the mimicry of self to the surroundings. 

 I have examined over fifty nests and found them 



■ all lined with the fluwer stems of the hair moss, 

 Folvtrichium, which is a distinctive trait throughout its 

 its breeding range, I believe. For a Warbler, it is a 

 remarkably persistent breeder, and will return vear 

 after vear to near the same spot, if not too often
