Some records of blood parasites from Ontario birds

NFORMATION on the occurrence of blood parasites in birds is still very incomplete. On reading Herman's (1944) summary of available information on the subject, the writer realized that he had a number of unpublished host records that could profitably be added to those in print, and that data on the rate of infection in 111 birds of various species were of some interest. These are arranged in Table The principal localities are Brule and Biggar Lakes in Algonquin Provincial Park, and Frank's Bay on Lake Nipissing. Isolated records from 9 other parasitized birds, where the rate of infection cannot be > given, are added.
