The tarsus length of house sparrows at fledgling stage was positively predictive for the tarsus length measured when individuals were recaptured later at full-grown size (n = 15) at the island Leka in northern Norway. Individuals from 2002 and 2005 are indicated with white and dark circles, respectively. In this analysis, the fledgling tarsus length was standardized to the age of 10 days to allow for small differences in the age at measurement. See §3 for further details.
