The shaman's ancestors spirit ability for the spirit animal is to allow it to speak some languages.
Does that mean that a monkey spirit animal with that spirit ability can use wands via UMD?
Spirit Animal
The shaman's spirit animal has streaks of gray or silver hide, hair, or fur, and long facial hair that appears similar to a wispy mustache or bushy eyebrows.
The spirit animal can speak and understand a number of bonus languages equal to the shaman's Charisma bonus.
Normally basic familiar can't do that because they either have hands (monkey) or speak (raven) but not both.
Edit: Does it need UMD for all spells including shaman spells?
