6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I49 



field sparrow, for each of which the total reported instances is less 

 than this number. 



House finch 



Carpodacus mexicanus (Miiller) 



Recently Wauer (1964, p. 299) noted a fledgling cowbird (race 

 obscurus) being fed by a house finch on June 17, 1960, in the Pana- 

 mint Mountains, California. It has been noted as an occasional victim 

 of the cowbird by a number of observers, but this is the first report 

 that it can and does rear the young of the parasite. 



Sharp-tailed sparrow 



Ammospiza caudacuta (Gmelin) 



Oscar M. Root (in litt., November 1964) reported a nest with four 

 eggs of the host and one of the brown-headed cowbird (M. a. arte- 

 misiae) found on June 20, 1962, in Dixon's slough, Gorrie School 

 District, Brandon, Manitoba, by John Lane. The only previously 

 reported instance did not give date or locality (Friedmann, 1963, 

 p. 157). 



Lesser goldfinch 



Spinus psaltria (Say) 



In addition to a few records of the lesser goldfinch as a cowbird 

 host in California (race .S\ p. hesperophilus) and one in Texas (near 

 Austin, race S. p. psaltria), a second in Texas, from Beeville, has 

 been reported (Webster, 1964). 



Lark bunting 



Calamospiza melanocorys Stejneger 



Since my 1963 account (p. 153), the lark bunting has been found 

 to be a cowbird host in Saskatchewan as well as North Dakota. In 

 1963, near Moose Jaw, Saskatchewan, George Fairchild (in litt., 

 November 27, 1964) found four nests of this bird, three of which 

 were parasitized. 



Oregon junco 



J unco oreganus (Townsend) 



Previously known as a victim of the cowbird in British Columbia 

 (race /. o. montanus) and in California (race /. o. pinosus), the 

 Oregon junco has since been found parasitized near Dishman, Wash-
