Marco Polo sheep live at altitudes above 4,000 metres, grazing on tough mountain grasses and surviving temperatures that drop far below freezing. Their thick woolly coats change colour slightly through the seasons, keeping them warm in winter and cooler in summer. Both males and females have horns, though the males' horns are much larger.
The males use their great spiral horns during their rutting season โ they clash together dramatically, making a crashing sound that echoes across the mountain valleys. Despite the noise, neither animal usually gets hurt. The horns are more about showing off strength than causing harm.
Marco Polo sheep travel in herds that roam across borders between Tajikistan, Afghanistan, China and Kyrgyzstan. Because they cross so many countries, wildlife experts from those countries have worked together to protect the herds. This is a wonderful example of countries helping each other to look after the animals they share.
