海岸の渡り鳥、シギとチドリたち
淡水の混じる海岸にトウネン、ヒバリシギ、ハマシギ、キョウジョシギ、キアシシギ、アオアシシギ、ムナグロ、メダイチドリ、シロチドリなどがいました。
ハマシギは1カ月前にも同所で見ています が、別の個体。シロチドリは足にメタルリングが装着されています。6月上旬に同じ場所でリング付きの個体を観察しており、同じ個体の可能性が高いです。
途中、猛禽類が突っ込みムナグロ数十羽の群れなど海岸のほとんどの鳥が飛び立ちました。猛禽は一瞬しか見えませんでしたが、おそらくハヤブサだと思われます。
Dunlin, adult. Late summer plumage — looking rather ragged. The long journey must be tough.
Lesser Sand Plover, adult male. Transitioning from summer to winter plumage.
Lesser Sand Plover, adult winter plumage.
Kentish Plover with a metal ring. Hard to tell whether it never had a flag or whether it came off somewhere along the way.
A Ruddy Turnstone that crossed right in front of me.
Pacific Golden Plover coming in to land.
Common Greenshank, summer to winter.
Grey-tailed Tattler, summer plumage.
Red-necked Stint, adult. Summer plumage → winter plumage.
Long-toed Stint, adult.
Flushed all at once by what appeared to be a Peregrine. Mixed in among the Pacific Golden Plover flock were Grey-tailed Tattler, Ruddy Turnstone, Lesser Sand Plover, Kentish Plover, and Red-necked Stint. The Red-necked Stint's small size really stands out. There's something endearing about such a tiny bird working so hard to keep up.
