RAPID SECOND NESTING BY ANNA'S HUMMINGBIRD NEAR ITS NORTHERN BREEDING LIMITS

Abstract

Anna's Hummingbirds (Calypte anna) were first reported in Victoria, British Columbia, in December 1944 and again each winter until 13 January 1947. Sightings continued through the 1950s (Taylor and Harper 1987), increased in number each year, and by 1970 the first individual was noted on the Victoria Christmas Bird Count. Numbers increased on subsequent counts, with 177 noted in 1998 (D. Pearce, pers. comm.).
