What is this beautiful bird??? I caught a cat with it in my garden. I tried cpr and blowing softly in his beak but it was gone. Im so upset. Could it be a juvenile goldfinch???

Oh what a shame. Yes, it's a Goldfinch, possibly one of this year's youngsters as I can't see any red on the face, I'm afraid that cats do kill a lot of birds every year especially young ones that are not street wise.
