<p><span>We estimated </span>annual<span> apparent </span>survival<span>, </span>recruitment<span>, and rate of </span>population<span> growth of breeding </span>Ruby<span>-</span>throated<span> Hummingbirds (Archilochus colubris), while controlling for transients, by using 18 years of capture-mark-recapture data collected during 1984-2001 at Hilton Pond Center for Piedmont Natural History near York, South Carolina. Resident males had lower apparent </span>survival<span> (0.30 ± 0.05 SE) than females (0.43 ± 0.04). Estimates of apparent </span>survival<span> did not differ by age. Point estimates suggested that newly banded males were less likely than females to be residents, but standard errors of these estimates overlapped (males: 0.60 ± 0.14 SE; females: 0.67 ± 0.09). Estimated female </span>recruitment<span> was 0.60 ± 0.06 SE, meaning that 60% of adult females present </span>in<span> any given year had entered the </span>population<span> during the previous year. Our estimate for rate of change indicated the </span>population<span> of female hummingbirds was stable during the study period (1.04 ± 0.04 SE). We suggest an </span>annual<span> goal of ≥64 adult females and ≥64 immature females released per banding area to enable rigorous future tests for effects of covariates on </span>population<span> dynamics. Development of </span>a<span> broader cooperating network of </span>hummingbird<span> banders </span>in<span> eastern North America could allow tests for regional or metapopulation dynamics </span>in<span> this species.</span></p>
