That is a canary bird.
I just recently got a bird but I know nothing about it. At first I thought it was a canary as it was similar with the colour and sound, although, I got told about an American goldfinch and it has the same markings and is an extremely small bird (I think it's a baby).
I'm suspecting this bird is not wild as it loves it's cage and i found it inside a friends house.
I am currently feeding this bird of canary food and it seems to love it also..
Can anyone tell me which breed this bird may be??
Thanks!
