カラシラサギ2羽、エリグロアジサシ飛来(動画あり)

カラシラサギが2羽、河口に飛来しました。午前中は1羽でいたが、午後には2羽に増えました。後日、さらにもう1羽やってきました。

エリグロアジサシは十数羽が飛来。すでにペアになっているようで、産卵、子育ても間もなく始まることでしょう。

Chinese Egret

Two Chinese Egrets. Pushed off their feeding ground by the high tide, they were getting along together on a rock.

Chinese Egret

They kept a little distance from each other at times, but on the whole things were peaceful. Once the tide went out and feeding time began, however, squabbles were constant… ^^;

ツバメチドリの子育て始まる(動画あり)

今季もツバメチドリの繁殖が始まりました。 昨年のコロニー とほぼ同じ場所に40ペア程度が抱卵。すでにヒナも何羽か確認できました。

順調にいけば、これから7月中旬ぐらいまで子育てが続くと思われます。カタグロトビやカラス、ムラサキサギなどが近くいくると警戒を強めていました。

繁殖期中盤 アカショウビン、サンコウチョウ、リュウキュウコノハズク、アオバズク(動画あり)

石垣島の野鳥たちの繁殖は連日の記録的な雨の影響を受けつつも順調に進んでいます。

リュウキュウアオバズクとリュウキュウコノハズクは、それぞれ1ペアの巣が大雨で水没したようで繁殖失敗していました。

そのほかのリュウキュウアカショウビン8、リュウキュウコノハズク4、アオバズク3、サンコウチョウ2、リュウキュウツミ3の繁殖は順調に推移しています。

ツバメチドリは孵化率が低いような印象。エリグロアジサシとベニアジサシは抱卵中。繁殖の早いコアジサシは巣立ちビナを連れて飛び回っています。リュウキュウヨシゴイは親離れした幼鳥を今季初確認しました。

先日のソリハシセイタカシギ は2羽から1羽に減りましたが、まだ滞在しています。

稲刈り後の田んぼにはキジバトに混じってベニバトが飛来していました。こちらは秋の渡りシーズンに向けて増加し、幼鳥も見られるようになります。

キンバト、アオバズク巣立ち、アカショウビン、ズグロミゾゴイ(動画あり)

6月も中旬を過ぎるとキンバトとの出会いが多くなってきました。ほとんどオス個体ですが、たまにメスも。巣内のヒナが大きくなってきているからだと思われます。

リュウキュウアオバズクは今季初の巣立ちを確認。この時期から7月の上旬にかけてがアオバズクの巣立ちのピークとなります。

リュウキュウアカショウビンも子育て真っ盛りで、そろそろ巣立つところも出てくるでしょう。

標識付きのリュウキュウコノハズクが子育て中。大学の研究者の方に聞いたら、波照間島で標識を付けた個体だそうです。メスが出生地から拡散することはよくあることとのこと。

6月9日に孵化した卵の殻を見つけたリュウキュウアオバズク のヒナは大きくなっているようで、メスが巣の外に追い出されていました。よく見ると巣穴からヒナの顔が見えました。巣立ちはまもなくのようです。

昨年、2羽が巣立ったカタグロトビ のペアは今年も同所で繁殖中。オスが見張り代に立って目を光らせています。
