This blog introduces the breeding and child-rearing struggles of little grebes in Inokashira Park in 2017.
On the day the chicks hatched, unwelcome neighbors came to see what was going on
■
On July 26 (2017), one chick hatched at two locations on the same day at Inokashira Park.
Eggs and hatched chicks are protected by the alternation of their parents.
One of the parent birds goes fishing. And the remaining one is not allowed to be alert for a while to protect the chicks and eggs.
Foreign enemies come when the parent bird becomes one.
If you give them a chance, the little chicks and eggs will be killed in no time.
In the photo above, a great cormorant is on the left, and a nocturnal bird called a night heron is on the right.
All of them are carnivorous, and if they like it, they probably came to eat chicks.
As it protects its eggs and chicks, it is fully aware that the little grebe's parent bird will not attack, and will approach it at close range.

To live because the creatures of our neighbors also come to food
I am always observing the surroundings.
You should be more careful about things that can be eaten, not to mention dangerous things to protect yourself.
The night heron seemed to know that the first grebe chick had hatched here today and flew straight into the nest.
They will know where the little grebe nests are, how many eggs they have, and when they hatch.
Night herons also came to the nest where another chick had hatched, and I was waiting for a while.
They pretend to know each other, but their inner feelings are super tense
The parent bird, who protects the child, was not afraid of the night heron's reconnaissance at all, and kept staring at the night heron without calling his companion.
Not only night herons but also great cormorants are aiming for chicks at the same time.
The great cormorant had already returned to bed at bedtime, but the night heron waited for a while before flying to another hunting ground.
