A doe and her nearly grown fawns. With mom’s help, these two young White-tailed Deer have successfully survived their first winter!

Here is what Wikipedia has to say about White-tailed Deer:

In North America, the species is widely distributed east of the Rocky Mountains, but elsewhere, it is mostly replaced by the black-tailed or mule deer (Odocoileus hemionus). In western North America, it is found in aspen parklands and deciduous river bottomlands within the central and northern Great Plains, and in mixed deciduous riparian corridors, river valley bottomlands, and lower foothills of the northern Rocky Mountain regions from South Dakota and Wyoming to southeastern British Columbia, including the Montana Valley and Foothill grasslands.
