I agree, its a bad idea.

Firstly if she/they are inexperienced, they might end up being the one who need the rescue.
Secondly she is using her emotions to think that it is a good idea, and where the emotions kick in judgement and common sense goes out the window and she might put herself in a bad situation . Especially when dealing with a hurt or stressed animal. They dont know you are trying to help, and when cornered they will fight back.
I know how much damage my parrot can do, and if there is a risk of other infections and help is a long way away, she can be in real danger.
Talk her into picking a support roll. Even build some cages etc ready to except displaced and injured animals and contact the authorities so they know you are ready or preparing.
If they know you can back them up they will be greatful.

I do know how she feels. I spent a number of years doing rescue work, mostly car accidents. The one I remember are the unusual, the really bad ones and every accident that involved a pet or an animal.
That usually nice and quiet pet doesn't act anything like a pet, more like a wild animal. Expect injuries, and bad ones. Leave it to the experienced, and let them get some local support happening first.

Also, this probable wont sound right, but sometimes well meaning inexperienced people can do more harm.
I have seen someone give a car accident victim who wasn't hurt bad a cigarette, while standing 2 feet away from a fuel spill leaking out of the back of the car. That put about 20 people in danger.
My brother had an old couple stop at an accident and offer a cup of tea to a lady who was sitting in a car and told not to move until the ambulance arrived. They (first rescuers on the seen) calmed her and was attending to the other car assessing the situation.
When she reached to grab the cup, she instantly died because her neck was broken. The ambulance and the second response crue arrived a few minutes later.
So question her and make her question herself if she can realy help, or will she possibly hinder.
