ited two eggs. On April 11, the nest contained seven eggs, and both 

 birds occupied the hollow. The birds left the nest when the tree was 

 ascended about half the distance to the entrance. Judging from the 

 existing conditions, the birds had occupied the place for many years, and 

 a pair is rearing its young there everj' spring. 



Empidonaz virescens. Greex-crested Flyc.\tcher. — A nest (in 

 course of construction) of the Green-crested Flycatcher was found by the 

 writer in a thicket, near Fleetwood, on June 9, 1906. On June 15 the 

 nest was found deserted and nothing has since been learned of the breed- 

 ing habits of these birds, although several pairs may be heard during the 

 summer in the same locality. 



Otocoris alpestris praticola. Prairie Horned Lark. — A pair of these 

 birds was seen during the smnmer of 1906, and again on June 3, 1907, 

 in the same locality. The species may probably prove a rare breeder 

 here later on. 



Zamelodia ludoviciana. Rose-bre.^sted Grosbeak. — A nest of the 

 Rose-breasted Grosbeak was found by the writer on May 28, 1905, near 

 Fleetwood. It was placed on a small red maple about 6 feet high and 

 contained 2 eggs and the broken remains of a third one. Ou June 9, 

 1906, a second nest, containing four about half full-grown young, was 

 found in another locality, while on June 20 a third nest, containing three 

 eggs, was found in the same locality. Several pairs are yearly nesting 

 in this locality. 



Helminthophila pinus. Blue- winged Warbler. — This warbler has 

 repeatedly been seen in this locality during the summer months, but the 

 writer has thus far not been able to learn anything about its breeding habits 

 and would be very thankful to any reader of 'The Auk' who is familiar 

 with these birds for any information that will better qualify him to find 

 its treasures. 



Wilsonia mitrata. Hooded Warbler. — The first and only nest of this 

 warbler that has ever been found in this locality, to the writer's knowledge, 

 was discovered on June 6, 1907, in a dense thicket at the foot of the Blue 

 Mountains. The nest was completed but contained no eggs. On visiting 

 the same locality on June 15, the nest contained four eggs. It was placed 

 about 18 inches from the ground and was saddled on a dead stick as well 

 as having been partly supported by a small branch of sassafras. 



Setophaga ruticilia. American Redstart. — The Redstart has on 

 several occasions been observed in this county during the summer months, 

 but its breeding habits remain to be studied by me. 



Sitta canadensis'. Red-breasted Nuthatch. — A Red-breasted Nut- 

 hatch was seen by the writer on a steep hillside in the Blue Mountains on 

 June 6, 1907. It is probable that the species is a rare breeder in the moun- 

 tainous portion of this county. — W. H. Leibelsperger, Fledtoood, Pa. 



Rare New England Birds. — The Boston Society of Natural History has 

 recently acquired for its New England collection, several rare or interest-
