We studied breeding ecology of the Grey-headed Lapwing Vanellus cinereus by tracing nesting of 31 banded adults and their precocial chicks in Ogura-ike Farmland, Kyoto, for five breeding seasons from 2007 to 2011. From incubation to chick-rearing periods, banded males and females of seven pairs took care of their offspring cooperatively and the monogamous mating system of this species was confirmed. The pair relationship was maintained over years, notably in two pairs which remained stable for four and five years, respectively, even after failure in breeding. Thirteen birds (four males, eight females, one bird sex-unknown) returned to the study area and nested on the same block of the paddy field. Thus, nest site fidelity in this species can be strong.

On 8 June, 2002, one fledgling Common Sandpiper was captured, banded and released on the Kizu River (34°52′N, 135°46′E) in Kyoto Prefecture, Japan. On the same date the following year, a breeding adult Common Sandpiper was captured, banded and released, using a slipknot loop trap. Common Sandpiper breed across the middle and higher latitudes of the Eurasian continent. In Japan, they breed around lakes and marshes, and on river gravels, from the Ryukyu Islands north through Hokkaido. Even though they are resident in the Kinki Region, breeding records to date had been limited to Hyogo and Wakayama Prefectures, and these reports are the first for Kyoto Prefecture. The flood plain of the Kizu River consists of gravel interspersed with small patches of reeds and willows. The breeding sites were all located between 80 to 100 meters from the river, on gravelly soil protected by dense grasses. In addition to Common Sandpiper, Long-billed Ringed Plover, Little Ringed Plover, Snowy Plover and Little Tern also nest along the Kizu River. Currently, these breeding grounds are though to be diminishing. Conservation measures, such as establishment of seasonal sanctuaries and strict regulation of off-road vehicles, are urgently required.

ケリの生活史や繁殖生態を理解するためには,成長段階の早い時期からケリ雛の性別を知る必要がある.本研究では,簡便かつ確実なケリ雛の性判定法を確立するために初毛羽の基部からのDNA抽出を試みた.その結果,初毛羽からPCR増幅に十分量のDNAを得ることができた.加えて,この方法により京都府南部における17巣30個体のケリ雛の性を,雌14個体,雄16個体に判別することができた.即ち,初毛羽からのDNA採取の手法は簡便であるだけでなく,雛へのストレスを軽減する手法として有効であることが示された.
