Thank you once again for placing your order with Windy City Parrot. I did a little digging into why your Lineolated Parakeet is so quiet and my guess is because he or she has no may to call out to.
It’s my understanding that generally Lineolated Parakeets are quiet unless they are communicating with another Linnie.
I thought because of your visual impairment you would appreciate the sound of a couple of Lineolated Parakeets chirping, so I included a link to a video so you can hear their tiny voices. Take care
