"Urban goshawks, breeding records" 6, Pre-breeding moments, pine cone play

Updated: Aug 11, 2022

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.

オオタカ、松ぼっくり遊び

Female playing by throwing pine cones



 


It's still November, and it's too early to start remodeling the nest for breeding.

For a while until the breeding season, each male and female spent an elegant time in the forest of the park.


Crow harassment is occasional but not as great as it used to be.

The reason may be that crows also have males who have better flight ability than females.

It seems that the males worked for hunting and gave the females the prey they had caught so that they could get a little fat and nourish for breeding.

It's hard to get this big pine cone



Males seem to try to keep females from spending too much effort on breeding.

For a while, the female had some time to play with the cedar pine cones that grow in the park.


I want a big pine cone, but I can't remove the big pine cone from the branch.

I struggled to remove it from the branch for a while, but it didn't frighten.

After all, I gave up and went to a small pine cone.

Only small pine cones can be easily removed, and I'm tired of pine cones!



I picked up a pine cone and kneaded it with my beak and legs for a while, but it was just a seed of cedar, which didn't move and I couldn't eat it.

It wasn't interesting for goshawks, and I quickly got bored, and this play didn't last that long.



オオタカと獲物1

Is it a gift for males and females who work for hunting?


It seems that the frequency of male hunting has increased.

Probably to fatten the female for breeding.

This time the pigeons were killed near the park.


It's a good treat that is worth eating even if you share it with a female.

The female, who saw the male who killed her feast, watches the male pluck the wings of his prey and cook in the distance.

A male who plucks its feathers to make it easier to eat



The male, who had finished plucking his feathers, disappeared with the female in the tall bushes of the forest.


The male came down immediately, but there was no hunted prey at hand.

The male seems to have handed over all his prey to the female.

Despite the large prey, the male and the pairing, who gave everything to the female without saying anything, seem to be completely confirmed.

When breeding begins, both males and females will grow their chicks while shaving each other until the fledging of the chicks, such as feeding and protecting the chicks from foreign enemies.

Before the breeding season began, the graceful moments of the goshawk couple were flowing into the park.
