Marsh Grassbird to acros

Marsh Grassbird used to be a scarce winter visitor to Ogura when I first arrived in Kyoto but it no longer seems to occur. There used to be 3-4 Japanese Reed Bunting each winter in the same area too but I haven't seen one for over 15 years. Given their similar breeding range and habitat it's interesting that both should drop off the local birding map.

It was a pleasant surprise that such a localised species was so numerous at Hotokenuma.

Asian Stubtail is quite a common breeder on the hills around Kyoto. It's a forest floor skulker but not shy and can be easily call in.

Japanese Bush Warbler is a very common species in and around the city. I've yet to see Korean Bush Warbler here but I have seen ssp borealis on Hegurajima in October so they certainly could occur. I've also heard singing Cettia c. canturians (Manchurian Bush Warbler) on Mishima in spring.

Pleske's Warbler is the only locustella breeding in Kansai, on islands off the Kii Peninsular. Others are possible on migration, Lanceolated has occurred in Osaka Castle Park for example and I've seen a Middendorff's at Ogura, but none should be expected.

Some years quite a number of Middendorff"s pass through Hegurajima and sometimes just sitting in the undergrowth is enough to get reasonable views. 10 October 2010.

Pleske's Warbler, Wakayama, July 2007. The bill is obviously much larger than that of Middendorff's.

Oriental Reed Warbler is the only breeding acrocephalus in Kansai and it's common in suitable habitat. I once heard about six Black-browed Reed Warblers singing in May at a site near Kyoto city and more recently a summer bird at Lake Biwa.
