DELAWARE VALLEY ORNITHOLOGICiVL CLUB. 13 



Rhododendron and laurel (Kabm'a laiifolia) are both present 

 in the deeper and more shaded nooks on the lower slopes, but 

 do not seem to occur on the higher portions, probably on account 

 of the lack of shade and moisture. Vast tangles of both of these 

 shrubs occur along the Aquanchicola creek. 



As my observations have all been made in late June, July 

 and the middle of August, it is fair to assume that practically 

 none but breeding birds were noticed. To be more exact, the 

 dates spent in the Gap region were: Julj' 9-14, 1900; June 24- 

 July 6, 1901 ; July 20-23, 1902 ; June 28, July 19-24 and 

 August 16, 17, 1903. The August observations were very few 

 and unimportant. 



The bird life is Alleghanian in character, the Black-capped 

 Chickadee, Rose-breasted Grosbeak, and several birds more 

 characteristic of this zone than of the Carolinian being among 

 those noted. A touch, however, of the pure Carolinian seems 

 to be felt, as the Worm-eating Warbler was noticed in the river 

 valley, and the Chat in a number of situations, in fact, once on 

 the very summit of the ridge. 



The lower woods seem to possess as characteristic species the 

 Wood Thrush and Red-eyed Vireo; the open farming country 

 the Catbird, Robin, Bluebird, Baltimore Oriole, Barn Swallow, 

 Purple Martin, Goldfinch and Quail; the upper slopes and tops 

 of the ridge the Blue Jay, Flicker, Maryland Yellow-throat, 

 Hairy Woodpecker, Black-capped Chickadee and Towhee. 



Unless otherwise stated the abundance of a species is under- 

 stood to be the same as in the vicinity of Philadelphia, and 

 where no annotations are given the species are understood to be 

 common and generally distributed. 



1. Nycticorax nycticorax namus. Black-crowned Night Heron. 

 Seen on two occasions flying along the river. 



2. Actitis macularia. Spotted Sandpiper. Noticed frequently 

 along the river banks, and probably nested in a piece of waste 

 land bordering the river, as here, on one occasion (June 28, 

 1901), two adults and one young were observed. 



3. Colinus virginianus. Quail. Heard and noticed frequently 

 in the farming section between the Gap and Slatington. 



4. Bonasa umbellvs. Ruffed Grouse. Probably moderately
