Who woulda thunk you could love a bird so much!
I know that feeling EXACTLY! Chaco bird, a male gray cockatiel was found in my father in law's front yard, he never got claimed by anyone so I ended up with him and named him Chaco.
Chaco made me fall in love with him more and more every day and he too, talked up a storm! He taught ME what HE knew and we bonded like you wouldn't believe. He was my first "bigger" bird as I'd only ever had a parakeet in the past. He wolf whistled, said pretty bird/birdie, he mimicked my phone ringing exactly, did squeeky dog toy and occasionally would flat out laugh, belly rolling laughter...who knew a bird could do that?!
Anyway, I never clipped Chaco's wings...he was such a good boy, he flew all over the house and one particular day, I was leaving to pick my kids up from school...was only going to be gone about 10 minutes. When I went to put Chaco away in his cage, he flew off (cause he didn't want to go back in his cage I'm sure) So rather than chase him around, I said to heck with it...I knew he'd be fine. I opened up the door to leave, Chaco flew and landed on my head just as I had stepped outside. I panicked and said..."OH NO! OH NO! And spun around to go back inside, but it was too late, he flew off my head, around the house 3 times and landed high up in a spindly alder tree.
I was DEVISTATED!!! I HAD to go pick up my kids...so I rushed to school, got them, we came home, put his cage on the roof of our house with treats and millet hoping he'd come to it...he never did. I was never able to catch him even though he lived outside our house for 3 days. He'd talk to me when I'd go outside and say "Pretty Pretty" he'd answer...but never came down to me. Each day, he was further and further from our house and on the 4th day I went out and called to him and he didn't answer so I knew he'd flew out of hearing range. I put up signs, I put ads in the local classified and on craigslist...and I cried.
It took me 5 years before I decided my heart was healed enough to have another bird...now mind you...I have and have had, TONS of animals, dogs, horses, cats, goats, fish...I've loved and lost many pets in my life...but loosing Chaco, a silly bird (to some), absolutely affected me.
We have 3 birds now, 2 tiels and a conure and OMG! I love them soo much! So believe me, I completely understand where you are coming from. And how awesome that he's talking to you...he must really love and feel comfortable around you and your family. He's very grateful for the "rescue" for sure!
Congratulations and enjoy him all you can, while you can.
Take care,
Toni
