I agree with Debbie, don't expect this little Goffin to like you. Parrots just don't bond with strangers that often.
An indifferent tolerance, a shy acceptance, or a spicy warning are more like what you may see. An outright interest in you would be rare.
A loving bond comes with time. It's something you must earn with parrots. It doesn't happen overnight.
Goffins are loving, comical little Toos, but they also have all the Too attitude, and you just can't predict how they'll accept your overtures.
You watch this bird interact with the owner and family. You watch her movements and attitude. If you like what you see, then go for it.
But don't expect a happy ending immediately. You'll be tearing her away from a family she loves, taking her to a new frightening place, introducing her to people she doesn't know.
Would you be jumping with joy in her situation? She won't understand you are helping her to a better life. She won't understand it's for her best interests.
You will have to understand her. You will have to give her time to acclimate herself to her new life. You will have to earn her trust. You will have to be very patient.
It's all on you.
I love my Goffin. She's such a sweet bird. I'd not give her up for the world. She does though have likes and dislikes I respect.
She likes my daughters better than me. I live with it and have my own relationship with her. It's been about 22 years now.
Make up your mind before you bring her home that what happens, happens. That this is her last move no matter what.
Give her the same respect you'd give a stranger. Be a friend to her. She'll decide if you can become more.
