Canaries were inoculated with a strain of Plasmodium relictum isolated from a mourning dove and maintained by blood passage through pigeons. Parasitemias reached a peak on the fourth day following inoculation in all but two birds, dropped sharply thereafter and remained at low levels through the tenth day of infection. An asexual cycle of twenty to twenty-four hours was observed, with matinal and synchronous sporulation. Gametocyte numbers were low throughout the infections and eleven merozoites, on the average, were produced per mature schizont. Signs of pathogenicity were not observed and all infected birds survived the active phase of infection. The host-specificity of the parasite is discussed.
