I've been chasing this documentary recently, and it's well-made. There's a shooting diary at the end of each episode. The staff have suffered a lot and even risked their lives in order to shoot high-quality footage of the city. The animals inside are all fighting for survival and reproduction. The most impressive is the penguin in the first episode. The parents went out to forage, and many of them were shot to death by the huge waves. Very few were able to return to the shore. Most With bloody wounds, it's really not easy. There is also the flamingo in the second episode, their courtship is very special, like diving into ballet, which is very funny.
