This blog introduces the breeding and child-rearing struggle of little grebes that bred in Inokashira Park in 2018.
The chicks who had been observing the previous year were wiped out. Let's see the whole story until the chicks grow up well this year! I started writing this blog.
In mid-September, dragonfly spawning began to be seen throughout the pond.
This time, I will talk about the disaster of the dragonfly that was eaten by the little grebe.

Things happened in the middle of mating with Dragonfly (Kooniyama).
On a sunny sunny day, the dragonfly's turn gracefully danced over the pond while mating.
The dragonfly warms up and is a perfect day for spawning.
Perhaps it was to protect myself from foreign enemies aiming for dragonflies, I went into a little shade.
It wasn't just a shade for the dragonflies.
It was Little Grebe who was waiting.
This place is where the little grebe nests near the gourd bridge.
Dragonflies are a great treat for Little Grebes.
Parent birds that are incubating are always hungry.
It seems that he stares at the dragonflies flying nearby and thinks, "Come on, dragonflies!" And "This water is sweet!"
The little grebe's neck slowly moves according to the movement of the dragonfly.
Then, the dragonfly seems to approach the little grebe by itself.
Grebes are just waiting in the nest.
What attracts dragonflies?
Do you feel that the little grebe nest is a good resting place?
Perhaps it was half shaded and densely populated with aquatic plants, so I felt it was a convenient place for spawning.
Pull a little more, be patient, be patient!
Dragonfly is just in the middle of mating.
The movement of the two dragonflies connected is slow.
The little grebe is directly behind the dragonfly and is out of sight.
Besides, the little grebe is in the shade.
Dragonflies are completely unaware that the little grebes are aiming for themselves.
Little Grebe, "Don't be impatient! If you make a mistake in the timing, you will run away, so pull it in enough!"
The neck moves slowly, but it seems that the aim is tightly aligned with the beak and the timing is right.
Alright, now! "Gaburi!"
The moment the dragonfly was close enough to the range of the little grebe, the little grebe stretched his neck at once.
It's a momentary event, and Dragonfly has no idea what's going on.
It's already stuck in the beak of a little grebe.
Dragonfly, I can't run away anymore. Will both of them be killed?
Little Grebe, "OK, I caught it!"
Do you catch two and eat them?
Dragonfly, the male escaped the difficulty, but the female became the meat of the little grebe.
Then, the male dragonfly attached to the back separated from the female and flew in the air.
Dragonfly, the male seems to have managed to escape the difficulty.
A little further away, he seems to have grasped the situation of what happened from the air.
Only females were killed.
It will be the meat of Mestonbo and Little Grebe, which were supposed to leave offspring.
"Tohoho ..." "Goodbye"
The dragonfly male who escaped the trouble flew to find his new partner.
There are many other male rivals.
"I have to find a female partner again!"
"It's hard to find a partner!"
"But I'm glad I couldn't eat it!"
The dragonfly larva, Yago, in the water was also caught by the little grebe! Dragonfly watching the situation
Carnivores are built on many lives.
It's a small grebe, but I wonder how many small animals it eats to grow up to this point.
Little Grebe can be said to be a crystal of small animals.
Even the dragonfly that has been eaten like that is a carnivore.
I was able to see what to eat, what to eat, connections in nature, the food chain, and the activities of life in Inokashira Park.
