"Little Grebe Parenting" Part 11, chicks with one less

Updated: Aug 12, 2022

This blog introduces the breeding and child-rearing struggles of little grebes in Inokashira Park in 2017.

The chicks did not hatch on July 29, and on the morning of July 30 (2017), all the chicks hatched at the gourd bridge and became four chicks.


When taking care of the chicks of the parent bird,

When the parent bird returns from the surface of the water to the nest, it steps on the side of the nest several times to inform the chicks.

The photo above is where the parent bird is stepping on.

The chicks who learned that the parent bird would return to the nest evacuated to the edge of the nest so that they would not be stepped on.

If you are late to escape, you may be stepped on by a parent bird.

Even if it is stepped on, it doesn't matter.

The little grebe on Nanai Bridge has three chicks even on July 30th.

They left the nest for a while and were constantly alert to the direction of the nest.

The egg of Nanai Bridge may have been killed by a foreign enemy.

There are only 3 chicks even though the eggs are gone.

Great cormorants are always waiting for a gap, and night herons are waiting for the sun to set across the edge. There are snakes and crows.

The egg may have been killed by someone.


One of the parent birds lowers the chick from its back and goes to the nest to see what is going on.

After checking the situation many times and confirming that there was no problem, the parent bird returned to the nest with the chick.

It is small and hard to see, but there are two chicks on the back of the left parent bird and one chick on the right parent bird.

I am very worried whether the chicks of Nanai Bridge, which has been the focus of attention of foreign enemies, will grow up safely.

Looking at the place where he is very cautious and evacuates with chicks well, it seems that he can grow chicks well even in the environment surrounding danger.
