| Résumé : | House Martins Delichon urbica were examined for moult in autumn at breeding colonies on a north/south transect in W Spain. Adults and some early-brood juveniles had started flight feather moult; most were in active moult immediately prior to migration. Estimates were made of the start dates of the laying of first clutches at various latitudes. |
