西表島と与那国島でバードウオッチング

西表島と与那国島の連続出張。空いた時間で軽くバードウオッチングしてきました。

今年は全国的に長雨や台風の影響のなのか秋の渡りが遅れており、ピークにはわずかに早かったようですが、西表島では大量のマミジロツメナガセキレイの群れに数羽のマミジロタヒバリが入っていたり、農耕地の電線にはブッポウソウがいたりしました。1泊でしたが、翌日には北風が強くなり上原航路は欠航。大原から帰る羽目になりました。

与那国島では、エゾビタキ、シマアカモズ、ツメナガセキレイの3種が大量に入っていました。エゾビタキは農道に数羽が固まって降りてたり、シマアカモズは10メートルから20メートル間隔であちこちに、ツメナガセキレイは数種の亜種が牧草地や畑、牛舎に群れていました。

初日と2日目はシギはセイタカシギぐらいしかいなかったのですが、4日目には、タシギやハマシギ、エリマキシギなどが入りだしました。

台風の北風が強まると鳥たちは風裏に避難してきたのか、宇良部岳の南側では高密度でアカハラダカとエゾビタキ、シマアカモズ、ツメナガセキレイが林道に集まっていた。その中で、1羽の青い鳥がいると思ったらなんとオオルリの幼鳥でした。

ほかには、田んぼや沈砂池でクロハラアジサシ、林道ではコサメビタキ、牧場ではキタツメナガセキレイかシベリアツメナガセキレイと思われる幼鳥などに出会えました。

与那国島では4泊の予定でしがた、帰る予定の19日から北風がさらに強まり飛行機が欠航。結局、台風17号も発生し、1週間もの間、与那国島に閉じ込められました。風も強く、やることもないので、宿で仕事をして過ごすという最悪のパターンに…。食材確保も大変で石垣島に帰ってくる頃には1キロほど体重が減っていました…。^^;

Blue-and-white Flycatcher

First-winter male Blue-and-white Flycatcher near Urabudake, Yonaguni Island. Encounters like this are extremely rare in the Yaeyamas and Okinawa.

Blue-and-white Flycatcher

Same individual as above. Stopping by the same spot again in the evening, it was still there. With the bad weather, it will probably stay a while.

Oriental Dollarbird

Juvenile Dollarbird at Komi, Iriomote Island. The bill lacks the reddish coloring seen in adults.

Chinese Sparrowhawk

Juvenile Chinese Sparrowhawk on Yonaguni Island.

Chinese Sparrowhawk

Another juvenile Chinese Sparrowhawk on Yonaguni Island. Of the dozen or so birds I saw along forest roads, only two were adults.

Red-throated Pipit

Among the large number of Eastern Yellow Wagtails at Komi, Iriomote Island, there was a Richard's Pipit.

Red-throated Pipit

Same individual as above. I shot it from all sides hoping it might be a Blyth's Pipit, but it is a Richard's Pipit.

Photographed near Yonaguni Airport. An individual (left) that appears to be a juvenile Eastern Yellow Wagtail of either the tschutschensis or plexa type. On the right is a juvenile Eastern Yellow Wagtail.

Citrine Wagtail

Juvenile White-browed Wagtail, one of many at Komi, Iriomote Island.

Isabelline Shrike

Tiger Shrikes were present in enormous numbers on Yonaguni Island. With the strong northerly winds, they were especially concentrated in the southern areas.

Grey-streaked Flycatcher

Grey-streaked Flycatchers are here and there all along the forest roads.

Grey-streaked Flycatcher

Juvenile Grey-streaked Flycatcher. Less wary than adults, so you can observe and photograph them up close.

Asian Brown Flycatcher

A very wary first-winter Asian Brown Flycatcher. In the field I thought it was a Dark-sided Flycatcher, but looking back at the photos it turned out to be an Asian Brown Flycatcher.

Ruff

Male (right) and female Ruff. Both juveniles.

Dunlin

Juvenile Dunlin. Rarely seen in the Yaeyamas.

Common Snipe

Two Common Snipe. Both juveniles.

Whiskered Tern

White-winged Tern moulting from juvenile to first-winter plumage (left), and adult winter plumage.

The sea around Yonaguni Island, rough from the north wind. Shortly after this, Typhoon No. 17 also formed and I was stranded on the island… ^^;
