This blog introduces the life of a goshawk, a wild drama that unfolded in front of the caretaker in an urban park Tokyo Japan from July 2017 to December 2018.
This nest is the strongest, but the leaves of this tree will fall off in winter. No, here!

The parent bird (mother) trying to expel the young bird wanders around in the forest of the park.
Apparently, a preview of the nest, all of which were originally made by crows and used for breeding.
A forest in this park, formerly a crow's paradise.
After many struggles between crows and goshawks, goshawks seem to have become the master of this place.
It wouldn't be a waste for the crows who were kicked out.
Crows haven't completely given up on this place either, and sometimes challenge the goshawks.
Sometimes the goshawk is inferior, but the goshawk has better flight ability and has sharp claws and beak as a weapon.
I'm sorry if the crow is also killed.
Knowing that, or being chased by a goshawk, the crow's hips will be pulled back.
The crow, who had been doing whatever he wanted until the goshawk arrived, had his shoulders narrowed.
The little birds who were always bullied by the crows said, "What the hell, I was wondering if the crows were stronger, but it's no big deal!"
The crows aren't solid, so my friends can be killed by goshawks! Be more solid and get rid of the goshawk. "I will hit the back.
Many hangers are used as materials for nests made by crows.
I think I borrowed a hanger hanging on a clothesline in the neighborhood.
The material is not made of plastic, but only made of metal.
It is thin, supple and sturdy, and the branches of trees can be caught well, making it ideal for nesting materials.
The crows may have come to imitate what some crows started.
Crow may like blue.
It looks like there are many blue hangers.
The goshawk seems to be riding on a crow's nest and checking various things.
In the goshawk's head, the eggs that he will lay in the future, the growing chicks, the receiving place for the food brought by his husband, and the feeding place.
And it seems that it is simulating various things for breeding, such as how to repel when a crow attacks.
After digging around the nest for a while, I went to another place.
"I can't balance!" The scaffolding was too small for a goshawk who started to gain weight.
While I was a little lost, the goshawk stopped at the tip of a fine-tipped tree branch.
It seems that he came here because he could see all sides, but it's okay to get on a tree branch, but it's too tapered.
"Balance!"
It's a 360-degree round, perhaps to balance while flapping its wings, or to look around.
Did you see where the nest was in an instant?
The balance was so bad that I immediately took off.
"This nest is a little low and too close to the ground."
A crow's nest is at the end of the flight.
She must have looked around in an instant.
I flew straight into this nest from an unbalanced tree branch.
After spending many days previewing, I chose a different nest instead of these two.
Goshawks choosing nesting locations, it looks as if we are looking for a tent setting location at the campsite.
Its importance is incomparable, a major future life-threatening problem for goshawks.
It takes days to find a place that you are comfortable with.
