Ringed 2cy Lesser Black-backed Gulls

For our research on the identification of 2cy Heuglin's Gull Larus (f) heuglini, it's eminent to determine the variation in plumages of 2cy Lesser Black-backed Gull L fuscus. Even though LBBG is a common species throughout most of W Europe, the plumage development in the three subspecies of LBBGs is not yet fully understood. In order to study the moult scheme and plumage development in 2cy LBBGs, we have decided to study only ringed birds of known age and origin. This page lists our complete dataset of ringed birds.

Thanks to the field work of several Finnish gull enthusiasts, the variation in ringed 2cy fuscus already has already been studied and published in considerabe detail. We therefore particularly solicit pictures of the western LBBGs taxa graellsii and intermedius. We encourage any bird watcher, ring reader, ringer or photographer to check if they have pictures of ringed 2cy LBBGs, preferably from the period March-August, that are not yet listed on this page. If so, please !
