. The Canadian field-naturalist. 168 The Canadian Field-Naturalist [Vol. 65 COURTSHIP BEHAVIOUR OF THE BOHEMIAN WAXWING' E. O. HOHN Department of Physiology and Pharmacology, University of Alberta.

Bent's Life History of North American Wagtails, Shrikes, Vireos and Their Allies (U.S. Bulletin 197, p. 64) remarks that the short statement by Mr. Swarth 1922, quoted below, is all that the author could find on the subject. The Hand- book of British Birds (H. F. Witherby et al, 2nd Ed., 1943) gives no information on court- ship in its account of the old world form, Received for publication February 26, 1951.
