what disarranged, and it had been deserted. This is the same instance 

 mentioned by Bent (1946, p. 191) and by me in another paper (Fried- 

 mann, 1949, p. 158). Apart from this one case, the only other record 

 is that of Simmons (1925, p. 172) in his hst of cowbird victims for the 

 Austin, Texas, region. 



Verdin 



Auriparus flaviceps (Sundevall) 



The eastern race of the verdin, A.f. annexus, has been reported on 

 a few occasions as a victim of the dwarf race of the brown-headed 

 cowbird. At Brownsville, Texas, in May 1924, I found five nests of 

 this little bird, one nest of which contained an egg of the parasite 

 as well as 4 of the host. The entrance to the nest was larger than 

 the entrances of the others; it may have been disarranged somewhat 

 by the cowbird when attempting to enter the nest. R. W. Quillin 

 wrote me many years ago that he had found a few similarly para- 

 sitized nests, all of which were in poor condition, with the neck or 

 entrance torn away, and all of which were deserted. 



Bush-tit 



Psaltriparus minimus (Townsend) 



Two races of this bird, one of the smallest victims of the dwarf race 

 of the brown -headed cowbu-d, have been found to be parasitized in 

 California — the coastal form minimus and the inland race calif ornicus. 

 Bradford (1928) at Rincon, Riverside County, June 24, 1926, found a 

 nest of 2 eggs with 1 cowbu'd egg partly buried under a new nest lin- 

 ing. This record I referred to calijornicus (1929, p. 256) but, on the 

 basis of present laiowledge of the ranges of the races of the bush-tit, 

 the report seems to be allocated better to minimus. H. W. Carriger 

 informed me that he found a parasitized nest of minimus at Irvington, 

 Alameda County, May 15, 1932, containing 8 eggs of the host, 2 of 

 which were punctured, and 1 of the parasite. Of the race calijornicus 

 there is the following record: Ashworth (1930a, p. 43; 1930b, p. 122) 

 found a nest in Ventura County, March 29, containing 7 eggs of the 

 host, 1 of which was partly buried under the feather lining of the nest, 

 and 1 Qgg of the dwarf cowbird. 



White-breasted Nuthatch 



Sitta carolinensis Latham 



As might be expected from its habit of nesting in holes, this bu'd 

 rarely is parasitized. Only five records have come to my attention — 

 three from Pennsylvania, one from Illinois, and one from New York. 

 In the last state, Reinecke (1912, p. 536) found a parasitized nest 

 near Buffalo. In Pennsylvania, two of the records were made at 

 State CoUege by R. C. Harlow, one on May 16, 1910, and one on
