Sika deer sika deer. All "Cervus" species can crossbreed and produce hybrids in areas where they coexist (for example, introduced sika hybridize with native red deer in the Scottish Highlands, where this is a serious threat to the gene pool of the red deer population). Serious genetic pollution has occurred in many populations, especially in China. Therefore, the status of many subspecies remains unclear. The status of "C. n. hortulorum" is particularly uncertain and might in fact be of mixed origin, hence it is not listed here. The sika deer is one of the few deer species that does not lose its
Animal track Animal track An animal track is an imprint left behind in soil, snow, or mud, or on some other ground surface, by an animal walking across it. Animal tracks are used by hunters in tracking their prey and by naturalists to identify animals living in a given area. Books are commonly used to identify animal tracks, which may look different based on the weight of the particular animal and the type of strata in which they are made. Tracks can be fossilized over millions of years. It is for this reason we are able to see fossilized dinosaur tracks in
