Two-barred Greenish Warblers Phylloscopus plumbeitarsus were observed and photographed on Hegura Island (37°51′05.1″N, 136°55′06.2″E), Ishikawa Prefecture, on three years: from 24th to 25th May in 2000 (3 individuals), on 20th May in 2001 (1 individual) and from 24th to 25th May in 2005 (3 or more individuals). They were distinguished from similar species (the Arctic Warbler P. borealis, Green Leaf-warbler P. nitidus, Greenish Warbler P. trochiloides, Pale-legged Leaf-warbler P. tenellipes, Sakhalin Leaf-warbler P. borealoides and the Large-billed Leaf-warbler P. magnirostris) by differences in the shape of the supercilium and wing bars, in the color of the legs, bill, and tip of the outer tail feathers, in their call, and in the wing structure. I also summarized the records of P. plumbeitarsus in Japan based on the data from the literature and personal communication. Eleven records (15 individuals or more) were obtained from 13th September 1998 to 29th May 2009 and seven records (11 individuals or more) occurred in mid and late May in 1999 to 2009.
