The Records of Two-barred Greenish Warbler Phylloscopus

plumbeitarsus in Japan

Yoshiki Watabe�

Abstract. Two-barred Greenish Warblers Phylloscopus plumbeitarsus were observed

and photographed on Hegura Island (37�51�05.1�N, 136�55�06.2�E), Ishikawa Prefec-

ture, 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 di#er-

ences 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.

Key words: Two-barred Greenish Warbler Phylloscopus plumbeitarsus, Hegura

Island.
