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.
There are now 4 eggs on the gourd bridge. May 11
Since the first egg was laid at Inokashira Park, a family of gourd bridges, eggs have been laid steadily once every 1-2 days.
The nest of the aquatic life house and the nest of the gourd bridge, two nests, made a total of eight eggs.

The little grebe behind the aquatic life house also laid four eggs on May 11th.
Eggs are being laid smoothly in the nests of both the Gourd Bridge and the Aquatic Life House.
It seems to lay one egg every day or two.
As of May 11, the little grebe near the gourd bridge has a total of four eggs.
The number of little grebe eggs in the Aquatic Life House, which began to lay eggs later, has increased to four in total.
The little grebe nest behind the aquatic life house, which I was worried about, has also been repaired and is now a fine nest, and it looks like I don't have to worry too much.
Everything seems to be going well, but I can be very anxious.
I can't see any fish in the pond.
I haven't seen a little grebe, which I often saw last year, catching a fish and holding it in its mouth.
Most of the food I caught was yago and shrimp.
I don't know if that is the cause, but it takes more than an hour to change the little grebe, and I feel that the frequency of change is very low.
Is it because it is difficult to catch food?
When I looked into the pond from the top of the bridge, I couldn't find any fish shadows at first glance.
Almost no aquatic plants can be seen, the mud on the bottom can be seen, and the discarded empty cans can be seen well.
On the water, a great cormorant with a strong appetite is drooling in the water.
The water is too clear, which is also uncomfortable for fish.
The cormorants on the ground can be seen from the water, and the fish can be seen from the cormorants.
It seems unlikely that fish will live in a place without such a hideout, and I think that the fish that lived there have already become part of the cormorant's body.
There seems to be no way to escape to the fish targeted by the cormorant in this place.
I was surprised to find out when the water was drained by the pond, but most of the shores of the pond (usually in the water) are concrete walls.
This makes it very difficult for small fish and small animals to live in.
There is no escape for fish chased by cormorants, and the concrete wall is used for drive hunting.
Only a small part of the pond is struck so that small fish and small animals can live in it.
Only the water is clear, and I think it is becoming more and more difficult for fish to live in.

From now on, aquatic plants will grow steadily, and the situation will change day by day.
I want you to grow into a small fish that you can't see now, and before you know it, you'll be asked, "Where did so many fish come from?"
Will these little grebe chicks be in time for hatching?
It is very interesting how the pond will be revived from now on.
I want to keep an eye on it in parallel with the observation of the little grebe.
Around this time, dragonflies began to fly over the pond.
