Spiza americana (Gmelin)

P. F. Elliott has informed us that parasitism of this species is very frequent in Kansas. Working in Riley County during 1974 and 1975, he found that 18 (94.7 percent) of 19 nests were parasitized, whereas the previous “high” for parasitism of this species was 78.2 percent (Zimmerman, 1966), also in Kansas.
