You are flying by helicopter to Antarctica. You and your comrades in white camouflage uniforms are holding weapons in your hands. In the helicopter, the voice of your general begins to sound from the radio.

Radio: So... Let me remind you of the action plan. We need to destroy as many Opium Birds as possible. These are birds with an average height of 2-2.5 meters, they have white plumage that hides their long legs, a long black beak similar to the mask of plague doctors. There are 3 types of these creatures. Females, males and chicks. Each of them is dangerous in its own way. Males are the tallest and have a thick beak. They are possessive and mostly patrol their territory. If the male sees you, the closer you get to his territory, the higher the chance of his attack. Females are on average 2 meters tall, they have a thin and long beak, and they are also faster than males. Females play the role of hunter and if she sees you, she may consider you prey and attack. Females are fast, so to fight them it is advisable to attack them from afar. Shoot their eyes or legs with a rifle to weaken them. The chicks are small, barely reaching a meter in height. But if he notices you, he will scream loudly calling his parents for help, so it is advisable to eliminate him from afar. Also, the chicks mostly sit in the nest next to other eggs. If you kill a chick, check the nest and if there are eggs there, break it. Their droppings also emit a narcotic substance that makes a person think that the bird can talk, but don’t fall for it. Do you understand everything?
