I'm still on the fence until I see his band ... there are subtle differences on this bird, somethings look like Trey, some don't. Could just be a family resemblance - Ivy looks like his Dad at times. Trey has similar characteristics to his Dad T-Rex. My biggest problem is that the barring on his sides is too dark and actually barred where I'm used to seeing speckles.
I'm not sure its Trey and won't be until I see his band or see much more of him on the cam. If its not him, I'd be very surprised if it isn't a family member.
And the bird is not behaving like Trey ... not sitting in the usual spaces. Have yet to see the two of them on the JR sign, even just sitting. Heck, except for this afternoon, I have yet to see the two of them "together" anywhere. She was talking to the other bird yes, but I don't know at this point. I have to see the band number.
