DELAWARK VALLEY ORNITHOLOGICAL CLUB. 13 



our northern warblers 'and thrushes, which up to the present 

 time seem to have been unable to adapt themselves to their 

 rapidly changing environment, is an interesting question. It 

 would certainly seem that, if the beautiful forests of our State 

 continue to perish at the present alarming rate, their fate as 

 summer residents in Pennsylvania is doomed. 



The following list includes only those species which were 

 actually observed by us either in Potter or CHnton counties. 

 In the case of the more rare and interesting species the exact 

 locality and date has been given; in all others the birds may be 

 regarded as having occurred throughout the entire region visited. 



List of Birds Observed During a Trip to Clinton and Potter' 

 Counties, Pa., June. 21-28, 1900. 



1. Ardea herodias. Great Blue Heron. — A single bird was

3. Philohela minor. American Woodcock. — Reported to be

 however, was observed by us, on .June 24. 



4. Aclltis macidaria. Spotted Sandpiper. — Not common, al- 

 though a few were noted along all the large streams. 



5. Bonasa uinbdlus. Ruffed Grouse. — Undoubtedly this bird 

 was common throughout all sections where the primeval forest 

 yet remained uncut. It was reported by residents to be abun- 

 dant in certain sections of Clinton Countj', and also in the 

 forest region around Oleona in Potter Count}'. Only a single 

 individual was noted by us in the deep woodland along the 

 upper Kettle Creek Valley. 



6. Zenaidura macroura. Mourning Dove. — Rather curiously, 

 my notes bear no record of a single dove. 



7. Accipitcr rchr. Sharp-shinned Hawk — Seen only once in 

 the Kettle Creek Valley, near Oleona. 



8. Accipiter cooperi. Cooper's Hawk.— Met with twice, once
