Neil Fergusson's Summary of the trip to the kantory list:
Hello,
Several of us drove up to Nikko over the weekend for a wonderful
birding trip. Although we failed to find our two main target species,
we were all rewarded with a great view of a HODGSON'S HAWK EAGLE [Kuma-taka].
Many thanks to Ikenaga-san and Katayama-san for driving/coordinating,
and to Tachikawa-san for organizing the lodging.
11/15- Nikko; Stayed in Lodge (coop w/ Forestry-Agric. instit.):
11/16 Nikko Ryuzu Yamano-ie (Nikko Ryuzu mountain lodge)
On the afternoon of the 15th and morning of the 16th, we
birded around the area near the lodge, including the trail to
the Yu-taki, and Senjougahara marsh.
The two basic targets were SOLITARY SNIPE [Ao-shigi] and
Northern Shrike, but we failed to find either.
After birding, we onsened at the lodge, then ate dinner.
On the 16th we again visited the trail to Yu-taki,
and Senjougahara marsh, followed by Yunoko and Ashiyo copper-
mine area (for GOLDEN EAGLE [Inu-washi], but dipped), and
Chuzenjiko lake.
The interesting lesson was that the habitat of the Solitary snipe
is very different from Common snipe. Ikenaga-san showed us the spot
where he could see the bird one year ago: for example, a 1.5 m deep
sand "gorge" carved out by a tiny trickle of water in a very open forest area near the
watererfall.
