9/11/10 Wajima Harbour

9/11/10: Gale force westerly winds with heavy rain and high seas. We walked to the harbour to check for anything sheltering there and found a 2w Mongolian Gull amongst the melee at the nearby fish factory. We caught the shared taxi from the hotel at 2.10pm and departed Noto Airport for Haneda catching the Friendly Limousine Bus to Narita and checked in to the Holiday Inn.
Juvenile Kamchatka Gull L.(c.) kamtschatchensis at Wajima Harbour

Kamchatka 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:
