Formosan sika deer period with a switch to Japan as the major export market. The intensive hunting of sika during the Dutch era must have severely decreased the population of sika. Sika populations continued to decline over the next few centuries as the human population expanded—the natural habitat of sika in the lowland plains was steadily converted to farmland, and later urbanized, as the human population increased. Hunting also continued. As a result, wild sika populations decreased steadily, and in 1969 the last known wild sika was killed.

Animal cracker Animal cracker An animal cracker is a particular type of small cracker/cookie, baked in the shape of an animal, usually an animal either at a zoo or circus, such as an African lion, tiger, bear or elephant. The most common variety is light-colored and slightly sweet, but darker chocolate-flavored and colorful frosted varieties are also sold. Although animal crackers are made with a layered dough like crackers, they tend to be sweet in flavor, but still technically a cracker and not a cookie. Other animal-shaped crackers and cookies are popular, such as Teddy Grahams, Goldfish, Hello Panda and Koala's March.
