Empidonax virescens (Vieillot)
To the data previously available (Friedmann, 1963:53–54), which indicated that the Acadian flycatcher was a not uncommon host, but usually not a very frequently chosen one in many areas, it may be added that in Pope County, Illinois, a high incidence of parasitism, as much as 50 percent (of 12 nests examined), was noted by Graber, Graber, and Kirk (1974:35). This is higher than has been found elsewhere, although in parts of Indiana and of Pennsylvania this flycatcher is a regular, fairly frequent host. Ontario may be added to the areas where this flycatcher is known to be parasitized; 1 nest (out of a total of 24 reported) has been so recorded (Peck, 1975).
