1. Deer Species: Amur leopards mainly prey on deer species such as roe deer, Manchurian wapiti, and sika deer. These animals provide a significant portion of the leopard's diet.
2. Wild Boar: Wild boars are also part of the Amur leopard's diet. They are large-bodied animals that offer substantial sustenance to the leopards.
3. Smaller Prey: The Amur leopard has a broad prey base and may also feed on smaller animals like hares, Manchurian marmots, raccoon dogs, and various bird species.
4. Fish: In certain seasons and when prey abundance is low, Amur leopards may occasionally consume fish from nearby rivers and streams.
It's important to note that the leopard's diet can vary depending on prey availability, environmental conditions, and seasonal changes. The leopards adapt their hunting strategies and select prey based on what is most accessible and provides the necessary nutrients for survival.
