Molly wears a bright orange dog collar to help make her easy to spot and warn off hunters. She can be recognized as a Mule Deer by her large, mule-like ears and black-tipped tail.
Molly was an orphan, and since she was raised by humans, she is very tame and friendly.
She loves both treats…
And having her head scratched.
I did see wild deer grazing in the grassy areas at the Southwestern Research Station, but they were all White-tailed Deer (Odocoileus virginianus), and thus not Molly's kin.
