We tested the reliability of using bill length to sex individuals and estimate the sex ratio at a stopover site in Iceland in May 2003 and 2005. Feather samples from 65 of 324 captured birds were used for molecular sexing, and generalized linear models (GLMs) were used to discriminate the sexes from body measurements of the molecularly sexed birds. About 3% of the 324 individuals were misclassified by… CONTINUE READING
