the shiny cowbird in the province of Pampa, Argentina, where Pereyra 

 (1937, p. 297) noted that it was unusual to find an unparasitized 

 nest of this bird. 



To the northern, nominate race of the red-breasted blackbird 

 should be referred a record of cowbird parasitism in Surinam, first 

 cited by me (1929, p. 120) on the basis of the Penards (1910), as 

 Lampropsar tanagrinus guianensis. I am indebted to Dr. Francois 

 Haverschmidt for correcting this old, erroneous identification. 



Red-breasted Starling 



Pezites militaris (Linnaeus) 



A single instance of this bird as a victim of the shiny cowbird in 

 southwestern Ecuador was recently reported by Marchant (1960, 

 p. 584). The local race of the parasite is M.h. aeguatorialis; the host 

 is P.m. hellicosa. 



Palm Tanager 



Thraupis palmarum (Wied) 



To the previous single record known to me (Friedmann, 1934b, 

 p. 345) may be added the data that Chagas (in litt.) found this tanager 

 to be a victim of the shiny cowbird in Minas Geraes, Brazil. Both 

 records have to do with the typical race of the parasite and of the 

 tanager. 



Brazilian Tanager 



Ramphocelus bresilius (Linnaeus) 



In Rio de Janeiro province, Brazil, Sick and Ottow (1958, p. 45) 

 found two parasitized nests of this tanager (subspecies dorsalis) — one 

 with 3 eggs of the host plus 1 of the shiny cowbird, on November 22 ; 

 the other with 2 eggs of the tanager plus 1 of the parasite, on 

 December 7. These additions to the very few previous records make 

 it appear that this tanager may be a fairly regular victim. 



Greater White-shouldered Tanager 



Tachyphonus rufus (Boddaert) 



A second record of this tanager as a host of the Venezuelan race of 

 the shiny cowbird recently has been published. Near Caracas on 

 AprU 24 GHHard (1959, p. 29) found a nest with 1 egg of the host 

 and 1 of the cowbird. According to information kindly sent me 

 by F. C. Lehmann V, a hitherto unpublished case of this bird as a 

 host of the Colombian race of the parasite was found in 1961 on a 

 farm near Bitaco, west of Call, by Alfred Kyburz. 



Golden-bellied Grosbeak 



Pheucticus chrysopeplus (Vigors) 



Marchant (1960, p. 584, 587) found eggs of the shiny cowbird 

 subspecies M.b. aeguatorialis) in two nests of this grosbeak (sub-
