Purpose of this gallery is to help bird ringers in sexing and aging birds they might encounter during their bird ringing research. Also, one of the aims is to show the great variability wild birds show. Not only the interspecific variability in colour and shapes but also the intraspecific variability, the slight differences in plumage between each individual and the variability in moult the birds show.
I hope photos in this gallery could be used as a complementary aid when reading about some aging or sexing techniques in bird ringing books as photos might be sometimes more illustrative as plain text or black and white drawings.
Gallery is regularly updated, and recent updates can be found in the gallery changelog.
