与那国島でオオノスリ、コホオアカ、ウミネコほか
与那国島へ5日間ほど出張。空き時間に少しだけ鳥見もしました。与那国空港の周りにはオオノスリ2羽、ノスリ、ハイイロチュウヒ、ハヤブサ、チョウゲンボウが集合。滑走路の草むらで小鳥などを捕まえているようでした。
島内では、シロハラが大量に滞在。追い場所では30羽以上の群れになっていました。数羽のアカハラも確認できました。シロハラとアカハラは祖納から久部良にかけての島の北部をメインに、ツグミは南牧場から比川にかけての南部で目立ちました。
コホオアカやツメナガセキレイ、ムネアカタヒバリ、ジョウビタキも強風の中で耐えていました。久部良漁港ではウミネコ2羽とユリカモメ4羽が逗留中でした。
A juvenile Upland Buzzard appeared in the distance.
A second Upland Buzzard also showed up. This one was far away too. The two birds were several hundred metres apart and showed no sign of interacting with each other.
A Common Buzzard, right between the two Upland Buzzards. A month ago on a work trip to Yonaguni Island I found a Steppe Buzzard, but this time there was none.
A few Little Buntings were sheltering from the wind.
A Pale Thrush with almost no wariness at all.
A flock of about 30 White's Thrushes had moved into the farmland.
Among the flock of 30 White's Thrushes there were also a few Pale Thrushes mixed in.
A Dusky Thrush at a ranch. At this time of year only small numbers have been recorded on Ishigaki Island, but there were plenty on Yonaguni Island.
A Red-throated Pipit still retaining some summer plumage on the face.
On this individual, the reddish colour on the face has almost completely faded.
Juvenile (Yellow-browed) Eastern Yellow Wagtail. Almost all the Eastern Yellow Wagtails were juveniles.
A juvenile Black-tailed Gull eating a Common Sandpiper. First-winter plumage.
The moult was more advanced on this individual than the one above. Black-tailed Gull, first-winter.
Black-headed Gull, adult winter. There were four of them.
A male Daurian Redstart was at the boat-haul-out area in the harbour. It seemed to be foraging — though I wonder what it was eating.
