| Résumé : | A BBRC review of British claims of 'Ehrenberg's Redstart' Phoenicurus phoenicurus samamisicus found that the degree of variation within both samamisicus and the nominate form of Common Redstart P phoenicurus was poorly understood. The review established the degree of overlap between males of these taxa and the findings are presented here. The prominent and extensive white wing-panel is unique to adult samamisicus and is not shared with either first-winter samamisicus or adult phoenicurus. The plumage of first-winter samamisicus appears more advanced than that of first-winter phoenicurus, and can closely match the appearance of adult phoenicurus in autumn. Those adult phoenicurus which show a white wing-panel on the tertials and inner secondaries may be safely separable from first-winter samamisicus only by loral colour (solidly black in the former, fringed paler in the latter) and the absence of moult contrast in the greater coverts. This paper will form the basis for reviewing past claims and assessing current ones. |
