REPOKT OF NATIONAL MUSEUM, 1893. 



Cowbird. One would naturally suppose that birds breeding in holes 

 in trees or under rocks would be exempt from this infliction, but this 

 is not the case. Perhaps among the strangest and most unlikely of 

 foster parents selected are the Red-headed Woodpecker and the Eock 

 Wren. 



]Mr. Williani G. Smith, formerly of Loveland, Colo., writes me that he 

 found a Cowbird's egg in a Kock Wren's nest which was placed under 

 a ledge of rock fully 2 feet from the entrance, and which was barely 

 large enough for the wren to squeeze through. It seems almost in)pos- 

 sible that a bird of this size would be able to enter the small pendent 

 nest of the Parula Warbler and deposit its egg therein in the usual 

 way; still this species is occasionally imposed on, and it is possible 

 that the egg is dropped in the nest with the beak. The following is a 

 list of species in whose nests eggs of the Cowbird have been found, 

 and undoubtedly a number of others yet remain to be added to it:
