Juvenile Kamchatka Gull L.(c.) kamtschatchensis at Wajima HarbourKamchatka Gull typically retains its juvenile plumage longer than Common Gull L.c. canus/heinei. Note the first renewed grey first-winter upper scapulars are just visible on this individual. This taxa appears longer-billed than Common Gull L.c. canus.
Second-winter Slaty-backed Gull L. schistisagus in Wajima Harbour
An advanced second-winter individual complete with pale iris and a predominently slaty-grey saddle.
Juvenile Vega Gull L. vegae in Wajima Harbour In contrast to UK Herring Gulls L. argenteus, dark-centred tertials with broad pale tips and narrow edges seemed the norm for the majority of juvenile Vega Gulls encountered on both Hegura-jima and Wajima.
Possible juvenile Mongolian Gull L.(c.) mongolicus
Pushing the boundaries but this juvenile Gull appeared rather coarsely-marked in appearance alongside accompanying Vega Gulls due to its scaly retained juvenile mantle and scapulars, evenly pale- and dark-barred greater coverts and its oak-leafed-centred and irregularly pale tipped and edged tertials. Looking, perhaps incorrectly, for an alternative identification Mongolian Gull would appear a close match. If so, both its paler hindneck and visible dark-spotted undertail-coverts would appear to lend support. For photographs of juvenile Mongolian Gulls in Japan see:
Second-winter Mongolian Gull L.(c.) mongolicus at Wajima Harbour Being the rarest and most poorly-documented of the cachinnans complex the finding of this obliging Mongolian Gull proved the highlight of searching through the Wajima Harbour Gulls. Note that it has yet to replace its outer two primaries. To see an image of another second-winter Mongolian Gull in Japan:
