"Urban goshawks, breeding records" 25, young birds with a strong appetite

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 in Tokyo from July 2017 to December 2018.


Father bird that entered the landing position with prey July 9



A few days after the chicks left the nest, the mother bird almost disappeared to the young birds.

Parenting seems to have been completely touched by the father bird.


This time, we will focus on young birds with a strong appetite.


 

The three brothers have become quite accustomed to flying in the sky while chasing and playing.

I'm always flying around, so I'm always hungry.

So I'm always waiting for my dad to bring food.

The father bird caught the prey and, as usual, came to the forest with the young birds.



As soon as I saw the children coming in with their prey on the branches, I immediately went to the next hunt. July 9th

As soon as they find the father bird that brings food, the three brothers fly toward their father to get food first.

At this time, the father bird gave the prey to the young birds by placing the prey on the branches of the tree, just as when the prey was given to the mother bird.

As soon as they see the young birds come to pick up their prey, the father bird immediately goes on to the next hunt.

The first thing that comes to food is the young bird that first reaches its branch.

The young birds fly for food.

However, just because you arrive at the beginning does not mean that you can eat a lot with priority.

The dads always bring food from different directions, so the young birds don't know where the dad will come next.

However, there are some fixed patterns in the flight route where the father bird brings the food and the place where the food is placed, so for each of the three brothers, the father will bring the prey from there next time. Shouldn't you put it here? It seems that each brother is waiting for food while predicting.

Even when I'm playing, I sometimes look far away and think like "I'll eat food first!"

The place where you usually stop is a place with a good view so that you don't miss the food.

It seems that the brothers, especially the two sisters, are watching each other so that he doesn't eat anything delicious alone.

This period also coincides with the period when not only goshawks but also various birds are fledging here and there.

The young birds that have just left the nest know almost nothing outside the nest and are still immature to fly.

Moreover, he has no way to dodge the goshawks that approach and attack at a tremendous speed.

For those little birds, goshawks, it will be a good prey to catch easily.

Probably because there are a lot of good-looking prey, the father bird catches the prey more frequently than ever at this time.

Still, it seems that it is barely enough to fill the belly of three young birds with a strong appetite.

This time it seems to put food there, the eldest son who always likes to play alone was a little late July 13th

The father bird looked sideways at the three children flying toward the food and placed the food on a tree branch.

The eldest son who was playing alone seems to be a little late.


As soon as I saw the three brothers gathered in the food, my father bird went to the next hunt again on July 13th.

After seeing the three children end up feeding, the father bird went on to the next hunt again.

The father birds often bring food, if not to say that they are good friends with the three siblings, so it seems that all three have eaten enough food so far.

While competing for prey with three brothers, we will learn various (evil) wisdom that only we can eat a lot of food from now on.

* It is only a guess based on the observation of three goshawk brothers, two females, one male and the caretaker, and there is no confirmation.
