N2  - Hybridization between the sittellas Daphoenositta chrysoptera leucocephala and D.c. chrysoptera is analysed and defined from 59 recently obtained specimens of the two forms and their hybrids in south-eastern Queensland and north-eastern New South Wales, and from older museum specimens from those areas and adjacent regions. Characteristics of age and sexual variation are identified and taken into account in the analysis. A character index for crown colour plus supplemental traits affected by hybridization shows that a true, 250-km-wide hybrid zone connects chrysoptera and leucocephala, and that there is a graded shift in the features of sittellas across the Lone. The historical factors likely to have affected the distributional history and hybridization of the two taxa are reviewed.
