White-tailed Deer doe and her young fawn following a well-worn cattle trail. This observation was made on an abandoned ranch in The Colony, Texas.
Here is what Wikipedia has to say about White-tailed Deer:
Since the second half of the nineteenth century, white-tailed deer have been introduced to Europe. A population of white-tailed deer in the Brdy area remains stable today. In 1935, white-tailed deer were introduced to Finland. The introduction was successful, and the deer have recently begun spreading through northern Scandinavia and southern Karelia, competing with, and sometimes displacing, native fauna. The current population of some 30,000 deer originate from four animals provided by Finnish Americans from Minnesota.
