Spinus pinus (Wilson)

To the 11 earlier records of parasitism on this bird (Friedmann, 1963:146–147) may be added 3 more. One of these, from Manitoba (Prairie Nest Records, Winnipeg) is the third case known to us involving the cowbird race M. ater artemisiae. The other 2, from Ontario, out of 11 nests reported to the nest records files at Toronto, refer to the nominate race of the parasite.
