Some zoo animals are more active in winter months due to the cooler weather and reduced daylight. Here are some examples of zoo animals that tend to be more active in winter and the best times to see them:

1. Arctic Wolves: Arctic wolves are well-adapted to cold temperatures and may become more active during winter. The best time to see them may be during the late afternoon or evening hours.

2. Snow Leopards: Snow leopards are native to mountainous regions and are well-suited for cold weather. You may have a better chance of spotting them during the day or early evening.

3. Red Pandas: Red pandas can tolerate colder temperatures and may be more active during winter months. Look for them in the morning or late afternoon.

4. Siberian Tigers: Siberian tigers, with their thick fur, can withstand winter weather. You may have a better chance of seeing them during the day or in the early evening.

5. Polar Bears: Polar bears thrive in cold environments. The best times to see them may be during the day or in the early evening.

6. Penguins: While not strictly zoo animals, penguins are often found in zoo habitats and are well-suited for cold weather. They may be more active during the day.

It's essential to check the specific zoo you're visiting for their recommendations on the best times to see different animals. Zookeepers may adjust the animals' schedules or provide additional information based on weather conditions and the animals' behaviors.
