Article summary

Vielliard considered, in July 1976, that there was no juvenile dimorphism by Sitta ledanti, and that all birds have a black crown. In June 1977, however, we observed that fledgings do not have a black crown. In November 1977, about 15 birds were observed and four captured : among them, one exemplar had no black crown, and another one an incomplete black crown.
