• Resumen

  • This paper presents an analysis of the biometrics of Dippers Cinclus cinclus at two localities in the Sistema Central mountains (Central Spain). Data of 19 Dippers from Las Cruceras (altitude 880 m, Avila) and 15 from Galíndez (altitude 1060 m, Segovia) were analysed. Males from Galíndez had significantly longer wings than those of Las Cruceras. No significant differences were found between females at the different localities. Likewise, no significant differences between localities were found in body mass either in males or in females. Differences between the two localities in environmental condictions and habitat quality, and differential movement patterns in the sexes may explain these results.
