Abstract

Criteria for ageing Hawfinches on a semi‐quantitative basis are analyzed. Age/sex classes can be recognized by scoring rectrix abrasion, width of the outer web of the sixth primary and sharpness of the greater alula feather. Based on these three criteria, age determination appears always possible.
