budgies health


Budgies can become ill when they are not cared for or fed appropriately. Providing good diet and right living conditions helps keep your budgies healthy and happy. Healthy bird is active, always alert, has good appetite, its feathers, eyes, feet and cere are clean, beak - smooth. Its droppings are dark green and white, toothpaste consistency. If your bird sits in one place, is not interested in its usual activities, its feathers are puffed up - it may indicate it's not feeling well.

"An ounce of prevention is worth a pound of cure"

If you think your budgie is not well, make a vet appointment as soon as possible. Budgies are preys in the wild, so they can instinctively hide a sickness to avoid being taken as vulnerable by potential predators. When they're part of a flock, they try to act as usual, otherwise other members may want to start to attack them or reject them, which is a natural behaviour in the wild. So they often look and act fine, even when ill and if you notice a change in your budgie appearance or behaviour, it probably means it's been sick for longer than it seems and needs medical intervention urgently.

Below - there are some common bird diseases or heath issues with symptoms. I'm deliberately not giving you ideas how to cure budgie illnesses, because that should be done by a vet, after detailed examination or tests.

Apart from the colour/shape/size/consistency of your budgie’s poops, it also matters -to spot an illness- how the poops are distributed in the cage (for that reason white paper towels are the best as a bedding in the cage, so that you can easily see if your bird’s droppings are normal). And now - what’s ok at night, is not ok during the day and the other way around. If your birds poops are cumulated in one place, in a pile, or very close to each other at DAY time, that means your budgie doesn't move too much. Budgies poop every 15 minutes so if you can see a lot of droppings in one place, it means you bird hasn’t moved from the spot for a few hours at least. And that’s the 1st indicator, something might be going on, health-wise. Budgies are naturally very active and move from one place to another every minute so if they sit in one place all the time - it’s unlikely a good sign. But when it comes to the NIGHT time - it’s good when the poops are just in one place. That means your bird has had a good, peaceful, undisturbed sleep. But if, after the night, you see their poops around the place, it means there is something that’s been bothering your bird at night. It might be feather mites for example. Normally, birds sleep through the night without the need to change a place. But if your birds are spread all over the place after the night, it suggests restless sleep and you should look into some other possible symptoms of an illness. Take a look at the picture below - hope it helps you visualise what I mean.

It's hard to list all possible diseases or conditions that can affect your budgie, but the ones I mentioned above are the most common. If you happen to have a sick bird and its symptoms are not listed above, please contact me and I'll try to help. However - if you think your budgie is not well, please seek professional, vet advice and help.
