Good advice above from Katherine. It’s hard to say from the pic. It’s always advised to bring new birds to the vet (an avian vet) for a new pet check up just to make sure all is well. When birds are ill, they mask their symptoms until they are so sick that they can no longer hide it. By then it might be too late. This is their survival instinct as a prey animal.
If you need help finding an avian vet in your area, let us know. If you’d rather not disclose the area you live in, shoot a private message to either myself or StarlingWings, and we’d be happy to help you locate one.
If you haven’t done so already, we ask that you read through the Stickies and Articles provided on this forum. There is a ton of helpful and important information to get you started with budgies. You’ll also find answers to more common questions.
Welcome, and enjoy!
