"Urban goshawks, breeding records" 37, goshawks disappearing from the forest

Updated: Aug 11, 2022

"The story of a goshawk, a bird of prey that has advanced into the city Tokyo Japan"


This blog introduces the life of a goshawk, a wild drama that unfolded in front of the caretaker in an urban park from July 2017 to December 2018.


 


After mid-August, goshawks almost stopped coming to the goshawk forest.

Or rather, it can be said at all.


Parent birds are probably the most graceful time of the year, as they are freed from caring for their children and still have months to prepare for breeding.

It seems that molting will be completed at this time.


Male goshawks, who have been particularly busy hunting, will have a break and recuperation for the next breeding for a while before preparations for the next breeding begin.

Even for females that have been exhausted by breeding, this is the time when it is necessary to completely finish molting, prepare for breeding next year, and rest the body.


During this time, goshawks from all over the world, freed from breeding, may be outing to see who is where and looking for new lands.


Goshawks are not migratory birds, but I think they are going out quite a bit for recreation during this time of year when they can afford it.



For goshawks, such as a distance of 10 kilometers, once you get on the updraft and get on the airflow, you will be able to glide in no time.

Even at a distance of 100 km or 200 km, if you feel like going, you can easily go on a day trip.

You don't even have to go on a day trip at this time when you're free from your children and your wife.


Even that little narcissus flycatcher crosses the ocean for hundreds or thousands of kilometers.

Of course, without any luggage.

I wonder if a superhuman person, such as crossing the sea with a canoe, would be "no big deal!" From a small migratory bird's point of view.

"We are empty-handed!" "We don't even have water!"


With that in mind, humans must be seen as miserable animals that can do almost nothing empty-handed.

It's probably a bad thing that made me crazy.



I'm very worried about where I went when I couldn't see this goshawk.


The caretaker continued to search around the Goshawk Forest while the Goshawks were no longer visible.

He wanted to know when and from whom he would come back.


From mid-August to the end of September, when the young birds disappeared from the goshawk forest, they saw the goshawk only twice.


Once, the goshawk quickly crossed the riverside, a little away from the goshawk forest.

Apparently it looks like a goshawk from somewhere else.


Feathers that look like those of young birds remain.


I'm sure it came from somewhere far away.

It seems that he hunted a while ago when he saw no goshawk of the Lord here.

It seems that I just caught something and ate it, and the throat part is bulging.


In the immediate vicinity of seeing this goshawk, I found traces of the dismantling of a small bird.

Probably the work of this goshawk.


This is the only time I've seen this goshawk, and I'm sure it's a passerby.

It seems that he ran away before he was mainly found.



Then, on September 22, I saw a male breeding here in the Otaka Forest.


Is it a preview for next year's breeding?

The male went somewhere soon after staying for a while on the treetops of the Otaka Forest.

Did I make a detour to pass by?


Then, I rushed into October without seeing any other goshawks.

The time when the cicadas were no longer audible and the wind was cool, and the cold winter was just around the corner.

Goshawks are once again frequently seen in this forest.

Preparations for breeding next year are likely to begin.


One year has passed since the beginning of this "Urban Goshawk, Breeding Record".

Last year, from this time of October, goshawks began to preview their breeding grounds.



Last year, we first met young birds and their parents in the Otaka Forest.

The young birds were then expelled and males and females began preparing for breeding.


What will happen to this year?
