engines. And another strange fact 

 about the nest it had a large wasp's 

 nest hung from the top, which had a 

 few live wasps in it. 



The nest contained six well marked 

 eggs — which were fresh.

Notes in the Red-eyed Vireo in the 

 Vicinity of Philadelphia. 

 The Red-eyed Vireo is one of our 

 commonest woodland birds and every 

 wood-lot or grove harbors at least a 

 pair during the breeding season. Dur- 

 ing the past eighteen years I have 

 found two hundred seventy nests of 

 this interesting species, excluding 

 those I have seen after the breeding 

 season. Of these nests one hundred 

 three were empty and the others con- 

 tained eggs and young as follows: 



15 nests contained 1 egg. 



27 nests contained 2 eggs. 



65 nests contained 3 eggs. 



24 nests contained 4 eggs. 



1 nest held 4 young. 



2 nests held 6 young. 



3 nests held 12 young. 



4 nests held 3 young. 



5 nests held 2 young and 1 egg. 

 1 nest held 3 young and 1 egg. 



1 nest held 1 young and 2 eggs. 



2 nests held 2 young and 2 eggs. 

 1 nest held I young and 3 eggs. 



Altogether 19 nests held 1 egg or 

 young. 



33 nests held 2 eggs or young. 



83 nests held 3 eggs or young. 



31 nests held 4 eggs or young. 

 Of the one hundred three empty 

 nests, the majority of them were sham 

 nests. 



These records show that the Red- 

 eyed Vireo, in this vicinity at least, 

 commonly lays four eggs and they also 

 indicate that clutches of two occur 

 more often than those consisting of 

 four eggs. Sets of three, however, is 

 the common number of eggs laid, and 



such clutches occur almost twice as 

 often as those of two and four eggs; 

 the single eggs were invariably in- 

 completed sets or were found in de- 

 serted nests. 



I have found the Red-eyed Vireo 

 nesting in the following varieties of 

 trees and bushes in this region, as 

 well as a few in unidentified shrubs.
