Geese and Ducks All Present

Jan. 25, 2024

The wintering ducks of Ishigaki Island are all assembled. Six Greylag Geese, Taiga Bean Geese, and Greater Bean Geese have arrived; in the rice paddies the most numerous ducks are Eastern Spot-billed Ducks, Northern Shovelers, and Eurasian Wigeons, while a large flock of Tufted Ducks is on the reservoir. Mallards, Eurasian Teals, Northern Pintails, Gadwalls, and Falcated Ducks are also present. This season I am seeing Mallard × Eastern Spot-billed Duck hybrids frequently.

Update, 3 March 2024

The six Greylag Geese that were on Ishigaki Island until around the end of January were on Kume Island as of late February. I hear a Smew is also there; since the Greylag Geese on Ishigaki sometimes used the same reservoir as a Smew, that bird too may have moved from Ishigaki.

The Grey-lag Geese have been here since last year — a long stay. All five are present.

Five Greylag Geese, Taiga Bean Goose, and Tundra Bean Goose

Five Greylag Geese currently staying. They are together with Tundra Bean Geese and Taiga Bean Geese. A group of five Greylag Geese — I hadn't seen that since two years ago in northern Okinawa Island.

Five Greylag Geese with a Tundra Bean Goose (right) and a Bean Goose (third from right). The Bean Goose is of the small type, so possibly the tundra form. All adults. The individual thought to be a Lesser White-fronted Goose appears to have separated from the flock.

Taiga Bean Goose subspecies and Greater Bean Goose

Two small Taiga Bean Geese together with Greater Bean Geese. They appear to be one of the smaller subspecies, but identification is difficult.

A small settling pond has Mandarin Duck, Tufted Duck, Eurasian Wigeon and others staying over. There was also an unidentified duck — I couldn't picture either parent for a hybrid, so domestic fowl may be mixed in.

カリガネ、ヒシクイ、オオヒシクイ、マガン飛来

Nov. 13, 2021

日を追うごとに寒くなる石垣島ですが、ガンの仲間も増えてきました。石垣島や沖縄では非常に珍しいカリガネもやってきました。ほかにはヒシクイが5羽、オオヒシクイが1羽、マガンが25羽の群れと別の場所に2羽滞在中。

先日の大陸から八重山にかけて吹き付けた強い北西の風に乗ってやってきたのかもしれません。

越冬中のチョウセンチョウゲンボウ、ヒシクイ、オオヒシクイ、マガンの群れなど

Dec. 27, 2020

先日のチョウセンチョウゲンボウの写真 があまりにもひどかったので撮り直してきました。警戒心もなく観察しやすい個体です。チョウセンチョウゲンボウは完全に越冬モードなので来春までは見られそうです。

ヒシクイ、オオヒシクイ、マガンの群れは9羽まで増えました。最初は 10月にマガン1羽11月にヒシクイ4羽 、いつの間にかオオヒシクイが3羽合流してしばらく8羽でいたのですが、つい数日前にさらにヒシクイが1羽追加され、現在は9羽の群れで越冬中。石垣島でこの数は初記録と思われます。西表島では過去にコハクチョウ9羽の記録があります。

サシバは沖縄本島に比べると少ないですが、それでも安定して越冬個体が見られます。

ツグミも日に日に数を増やしています。ことしはハチジョウツグミは少ないですが、石垣島では年によってはツグミが少なく、ハチジョウツグミだらけのこともあります。

ことし生まれのリュウキュウヨシゴイは換羽が進んでいました。
