She died
She was fascinated by a big bird.
She can not return to the nest. It is because a fellow parent bird kills her.
It is a bird's habit.
Her parent bird does not welcome her.
She once left the nest.
Parent birds do not recognize her as her own child.
It is a bird's habit.
They and they can eat in the morning, noon and evening. By the big birds.
It is a natural law.
It's very tough.
She was eaten.
This is a seagull chick.
A big bird struck a chick.
Parent birds and fellow birds squeezed big birds.
And the chick fell into the sea.
But parent birds don't help chicks.
The chicks away from the nest are abandoned.
Similarly, eggs that fall from the nest are abandoned.
This is a habit.
When the chick returns to the nest, it is killed by the parent bird.
The reason is that once the chick leaves the nest, the parent bird cannot recognize the chick.
Seagulls have a strong sense of territory.
Attacks when a friend's parent bird or chick approaches.
This behavior is because seagulls do not increase too much.
Many seagulls are together to protect themselves from foreign enemies.
There are 500 chicks.
The chick can survive only 30%.
Enemies hit about 20 times a day.
The chicks can be eaten by their parent birds.
It is cruel.
島根県　経島のウミネコ繁殖地のヒナの様子です。
2019年で今年は過去5年で一番ヒナの数が多いそうです。
500羽以上のヒナと150個の卵が確認されています。
しかし、生き残れるのは3割です。
過酷な運命が待っているのです。
ヒナの死亡理由のいくつかをあげてみたいと思います。
①迷子になって他の親鳥に殺される
②兄弟から攻撃される（生存競争のため）
③トビにさらわれる（カラス）
④暴風雨にて体温低下など
