アカオノスリの成長 Red-tailed Hawk Growth


今年、4月にアカオノスリが巣の上で卵を温めている所を発見しました。そして、5月12日に訪れた時、産まれていました。まだ綿毛のようにフワフワの赤ちゃん羽。 We found a Red-tailed Hawk nest in April this year. Both parents sat on the eggs during the incubation period. We visited the nest again on May 12. By this time two chicks were already born. Their feathers were downy baby feathers and they were simply fuzz balls.

5月18日に再び訪れた時には、茶色い羽が少し見えるようになっていました。 On May 18th, we visited again. We could see some brown colored feathers on them.

右側の子は足を前に出して座っているようです。鳥って、こんな座り方するんでしょうかね?子供と時だけかな。 Pay attention to the chick on the right. It seems it is sitting on its butt and large feet are out in front. I didn’t know that they can sit like this. Can they do it only when they are babies?

6月1日に訪れた時には、ほとんど茶色い羽が生えそろっていました。 On June 1st, their backs were all brown already.

もう、中学生ぐらいの子供です。They already look like Junior high kids.

でも、まだまだお母さんたちほどは大きくなっていません。お母さんが飛んでくると、こんな感じで巣穴はほとんどみえまくなってしまうほどなんです。 But they aren’t as big as their mom. When their mom flies over the nest, her wings cover the entire nest. She is that much bigger.

5月12日、お母さんと一緒。 With mom on May 12th.

5月18日。 With mom on May 18th.

6月1日。With mom on June 1st.

6月1日の段階で、まだお母さんから食べ物をもらっています。巣立ちまで40日から45日と言われています。今日はすでに6月6日、5月1日に産まれたとしたら、あと1-2 週間ぐらいかもしれません。巣立つ前にもう一度会いに行きたいです。 They are still getting food from their mom’s beak as of June 1st. According to the study, it takes 40-45 days before they fledge. Today is already June 6th. If they were born on May 1st, they could fledge in 1-2 weeks. I want to see them one more time before they are ready to go.
