a nest containing four practically un- 

 marked eggs. 



The nest was composed of dry Oak 

 leaves and was well lined with black 

 rootlets. It was situated in a clump 

 of young elder shoots; and was be- 

 side a small growth of elders stand- 

 ing on a sandy flat, close to a run of 

 clear water, deep down in a wooded 

 ravine. 



The four eggs which this nest held 

 are of the usual size, but they are 

 perfectly white with the exception of 

 a few pinpoint dots of yellowish- 

 brown that are scarcely discernable. 



Although I have examined some 

 forty nests of Oporonis formosus, this 

 was the only nest containing unmark- 

 ed eggs.

 Waynesburg, Pa. 



Edward R. Ford of Chicago, reports 

 the following unusual sets: Field Spar- 

 row, two eggs, and five Cowbirds in 

 the same nest, all being incubated by 

 the diminutive Spizella. 



A Meadowlark nest containing four 

 eggs of the Meadowlark, one Cowbird 

 and one Bobolink. 



Winifred W. Lyon reports four 

 Sandhill Cranes in the Calumet River 

 region near Chicago, May 2d. These 

 birds are getting scarce. 



He also reports Bufflehead and Rud- 

 dy Ducks staying in the Jackson Park 

 Lagoon at Chicago. This shows the 

 disposition of these birds to seek the 

 protection of humanity when it is ac- 

 corded them. 



Walter A. Goelitz of Revina, 111., 

 reports the unusual find of a Towhee's 

 nest with one egg of the owner and 

 eight of the Pavacite Cowbird. 



The Warblers of Warren Co., Penna. 

 Warren Co., Pa., is rough and moun- 

 tainous. 



Warren on the Allegheny River, is 

 1200 ft. above sea level and some of 

 the highest ridges are close to 2200. 

 A great part of the county is wild 

 land. As much of this wild land is 

 covered with a hemlock growth and 

 the conditions are very much Cana- 

 dian, a number of birds including 

 some of the warblers that usually 

 breed farther north are well repre- 

 sented here in summer. 



For this same reason there are sev- 

 eral of the warblers that are found in 

 this state farther south of us that I 

 have only seen on several occasions 

 or not at all. 



In early May when the warbler 

 flight is on in full swing the trees 

 and shrubbery is beginning to leaf 

 out along the river valley but back on 

 the hills has hardly started. This 

 causes the earlier part of the migra- 

 tion to follow the valley and after 

 rains or storms are sometimes very 

 abundant in favorable places along the 

 river. More species of the warbler 

 family are found in this county than 

 of any other family of birds. 



In Pennsylvania about 40 species of 

 warblers are known to occur or have 

 occurred and of these I have noted 30 

 species in Warren County. Of these 

 I have found 16 species breeding, hav- 

 ing personally taken eggs within a 

 few miles of Warren. 



The following is a brief list but may 

 be of interest to some of Pennsyl- 

 vania readers of THE OOLOGIST who 

 live where the conditions are differ- 

 ent: 



1. Black and White Warbler— Rath- 

 er scarce as a summer resident but 

 common as a migrant spring and fall. 

 A few pairs are scattered about dur- 

 ing the breeding season. 



2. Golden-winged Warbler — Rare, 

 Took an adult pair in July, 1905, anAl 

 saw an adult May 28th, 1911 and one 

 May 23d, 1913.
