THE D. V. O. C. COLLECTION. 



In 1 89 1 several members of the club presented to the Academy of 

 Natural Sciences the nucleus of a collection of the nests and eggs of 

 Pennsylvania and New Jersey birds, to be known as the Delaware 

 Valley Ornithological Club Collection and to be kept separate as a 

 local collection. In ten years this has grown until it occupies five 

 large museum cases, while specimens of nearly all the birds known to 

 occur in these states have been added. The nests are almost all in situ, 

 the branches being supported on walnut bases. The woodpeckers, nut- 

 hatches and other similar nests comprise an entire section of tree trunk, 

 while ground nests are carefully mounted in plaster or papier-mache. 

 At present there are represented the nests and eggs of 112 species, all 

 taken within the boundaries of Pennsylvania and New Jersey. Of 

 three of these, however, only the eggs are shown and of five only the 

 nests. 



The club is very anxious to complete this collection as far as possible 

 and asks the aid of its correspondents and omithologii.ts in general, in 

 securing specimens of the nests or eggs of any of the following from 

 within the above limits. 



Some on the ^ist should be easily obtainable, others are doubtful as 

 breeders within the limits given, while many of the shore birds breed 

 no more on our coasts. Eggs of these latter obtained in New Jersey are 

 doubtless in many collections, and information relating to such will be 

 gladly received. Communications should be addressed to Witmer
