@Polaris the Passive Abilities wording had to be changed since they were originally her Species abilities which didn't have limits
Here is what they used to say
Flight - as creatures descended from Bird's Avian's can use there wings to fly short distances but need thermal updrafts to stay afloat for an extended period of time. and if it gets to cold they will plummet to the earth
Extended Life Span - due to living up in the mountains for generations they've been getting clean pure air which has slowly extended there life spans. on average they live to be about 200 years old if they pass away from natural causes
Exceptional Eye Sight - on average they can see a Mouse up to a Mile away but any instant stimuli can easily blind them
Above Average upper body Strength and Mobility - due to strong flight muscles in there shoulders they can lift considerably more than the average human and by using there wings to create a momentum there also slightly faster.
