Mule deer
Odocoileus hemionus
The large-eared deer of canyon edges and the Morongo Valley corridor, mostly at dusk.

In the basin
Same corridor sentence as bighorn and mountain lion. Deer on Highway 62 and canyon roads are a dusk collision risk. Feeding them pulls a mountain lion’s food to the house. Wikipedia and CDFW’s ungulate page have the living-with notes.
