the usual 2 of the host. The late K. D. Camp told me at the time 

 that once he had found a similar case in the same area years earlier. 

 The ground dove in these two cases is of the subspecies C.p. pallescens. 



Yellow-billed Cuckoo 



Coccyzus americanus (Linnaeus) 



This bird has been reported as a victim of the brown-headed cow- 

 bird on three occasions. W. E. Loucks found a cowbird's egg in a 

 yellow-billed cuckoo's nest near Peoria, Illinois, some time prior to 

 1893. Trautman (1940, p. 273, 393) recorded a nest containing 5 

 eggs of the cuckoo and 1 of the cowbu'd at Buckeye Lake, Ohio. In 

 the collections of the Museum of Natural History of the University 

 of Minnesota is another record — a parasitized set of eggs taken at 

 Farmington, Connecticut, by Franklin Benner, on June 8, 1875. As 

 I stated m an earlier paper (1949, p. 158), the Loucks record is the 

 basis for the inclusion of this cuckoo in Bendire's list (1893) of cow- 

 bird hosts, presented therein without any supporting evidence. The 

 parasite in both cases was of the typical race M.a. ater. 



Black -billed Cuckoo 

 Coccyzus enjihrophthalmus (Wilson) 



Three parasitized nests of this cuckoo have been reported. One near 

 Buffalo, New York, was found by Morris and Fames (Friedmann, 

 1943, p. 353); one in Maryland was reported by Stewart and Robbins 

 (1958, p. 329). The data on the latter instance, kindly sent me by 

 R. E. Stewart, are that the nest contained 1 egg of the cuckoo and 

 1 of the brown-headed cowbird; it was observed in Anne Arundel 

 County, Maryland, May 26, 1932. The third case, a nest with 2 eggs 

 of the cuckoo and 1 of the cowbird, was found at vSte. Dorothee, Laval 

 County, Quebec, June 15, 1938, by Wm. J. Brown of Westmount, 

 Montreal. I am indebted to Mr. L. M. Terrill for sending me this 

 record. In all tlu-ee cases the typical, eastern race of the cowbird is 

 involved. 



Ruby-throated Hummingbird 



Archilochus colubris (Linnaeus) 



The ruby-throated hummingbird is in this catalog on the basis of 

 one record, unfortunately without supporting details. According to 

 F. B. Webster (1891, p. 109), M. S. Culver of Medford, Massachusetts, 

 in July, 1890, found a nest of this bird containing a single cowbird's 

 egg. I commented earlier (1929, p. 207) that I could not help but 

 wonder if the nest might have been a wood pewee's, but it seems better 

 to assume that the observer correctly identified what he saw, especially 

 since he noted that the egg completely filled the nest.
