Our adopted macaw sounds like he's got a stuffy nose / cold. His previous owner kept him in the garage, and he stayed outside a lot. We have him in our house with the central air conditioning unit on. The last 2 days, he's been like panting kinda sticking his tongue out. When he talks, he sounds kinda hoarse too. Is this something that can really hurt him? Is there anything we can do for him?? He's really adapted good, and is doing great other than this.
