Thraupis sayaca (Linnaeus)
Previously (Friedmann, 1929:111; 1931:56) there were 3 records of this tanager as a victim of the shiny cowbird, both involving parasitic eggs found in nests, 2 in Tucumán, Argentina, and 1 near Rio de Janeiro, Brazil. That the sayaca tanager is a true fosterer and not merely a victim is now made definite by an observation of a fledged young cowbird attended by this species in Tucumán, 8 January 1970, by J. R. King, to whom we are indebted for this record. Still another Tucumán record, a parasitized set of eggs taken at Manchalá, 28 October 1929, is now in the Museo de La Plata.
