"The story of a goshawk, a bird of prey that has advanced into the city"
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.
White and small chicks, they grew so big in 3 weeks,

Prey that the father regularly carries several times a day, perhaps because he is good at hunting.
The chicks seemed to have almost no inconvenience in feeding, and all three chicks grew steadily.
The forest of the breeding park is small, but there are many facilities such as grounds and schools around the park, so it seems that fathers who hunt will not have much trouble with the hunting ground.
In addition, there are many small birds who have been alert and have little fear of being attacked by birds of prey, let alone fat pigeons that have been fed.
Perhaps the city is an environment where it is easier to catch prey than natural forests.
Three weeks have passed since May 26, when the caretaker first saw the chicks, and more than half of the feathers of the white chicks have fallen off, and the feathers of young brown birds have appeared.
Although the chicks are still innocent, the appearance of the goshawk as a bird of prey has come to be glimpsed.
Restless legs syndrome chicks
At the time of a big change from a baby to an adult, the body grows bigger every day, and the feathers are in the middle of the change, and when I see the mottled feathers, it seems very itchy.
Also, the muscles of the body, especially the muscles that move the feathers, seem to be itchy, and the brothers all flutter the feathers over and over again.
The body keeps its wings moving.
In this way, it seems that the muscles for flying while fluttering the wings are being trained.
Mother bird returning to the nest with prey
As the chicks grow and grow larger, the mother bird often leaves the nest with peace of mind.
Mother birds away from their nests seem to be aiming for prey from high ground.
A dull body without hunting for a long time to raise children.
It will take some time to warm up to regain the intuition of hunting.
It seems that the mother does not leave the hunting to the father alone, but aims for prey to supplement the household budget.
It seems that the three chicks, which grow larger day by day and increase their appetite, anticipate that the amount of food will not be enough just by hunting their father when they grow larger.
Every day, it is interesting to see that the division of labor between father and mother birds and a lot of wisdom are hidden in order to succeed in breeding.
