Résumé :	Biometrics of the Redshank migrating in autumn through the Gulf of Gdansk were studied between 1983 and 1990. A total of 78 adult Redshanks and 775 juveniles was caught and measured. On average all measurements of adults were longer than those of juveniles. Almost all measurements of juveniles differed significantly among half-month periods, but not seasonally (except wing length). There was a significant decrease in tarsus plus toe length from the second half of July to the first half of September. Similar trends were shown in total head length and wing length. These facts correspond with dates of arrival of birds from the "southern" and "northern" populations.
