1 – Weigh your bird
Birds are prey animals. Evolution has taught them that if they look weak they are more subject to an attack by a predator in the wild. Thus it is not uncommon to see a bird appear to be healthy one day then fall over dead the next because there’s no visual symptoms like you can see with a cat or dog.
One of the most precise tools you can obtain for a mere $19 is our best bird scale ever which can be used to weigh birds from budgies to large macaws.
When you weigh your bird regularly at least twice a month you can easily see large swings in weight gain or loss possibly indicating an illness without being visible by looking at the bird.
