Abstract

Measurements of maximum wing chord, third primary length, tarsus length and body mass were analysed for 93 Bluethroats Luscinia svecica cyanecula captured at two localities in the Montes de León (León, NW Spain). Comparison of the measurements of males and females showed differences in maximum wing chord and third primary length; these are revealed as useful measurements for discriminating the sexes. In contrast, no significant sexual differences emerged in the measurements of tarsus length and body mass. Comparison of these same measurements between young and adult males produced differences only in the length of the third primary.
