Abstract

We compared reproductive success and territory fidelity in Black Oystercatchers (Haematopus bachmani) in the Strait of Georgia, British Columbia. Twenty-four of 34 nesting pairs hatched eggs in at least one year of the study, and of which 16 pairs raised chicks that fledged. Mean fledging production for 34 pairs in 1996 and 1997 was 0.44 fledglings per breeding pair per year. Thirty of the 34 pairs observed used the same territory, in 1996 and 1997. Of the 30 pairs that occupied the same territory in both years, 16 pairs failed to raise chicks in both nears, seven pairs fledged chicks in one year and sewn pairs fledged chicks in both tears. Oystercatchers showed stronger site fidelity to territories where chicks were fledged than territories where they failed to raise young.
