Abstract/Summary

This short report describes how we tested the reliability of a proposed bill character for separating Marsh Tits and Willow Tits of several European races in the hand. Pooling all samples (395 birds), the probability of accurately identifying an unknown bird as a Marsh Tit or a Willow Tit, based only on the presence or absence of pale marks on both sides of the upper mandible, was 98.0%. The bill criterion was therefore validated as a highly reliable method of separating Marsh Tits and Willow Tits.
