A bird that hides its illness
According to the MSD Veterinary Manual, birds hide illness so as not to appear weak. VCA Animal Hospitals adds that by the time signs appear, the bird has often been ill for several days to several weeks. Feathers can also hide serious weight loss or a swollen abdomen, the veterinary edition of the MSD Manual notes.
The first clues are subtle: a budgie that no longer sings in the morning, plays less or comes to you less. Knowing its habits is how you spot what is changing.
Signs to watch for
- Fluffed-up feathers, a bird sitting puffed up, sleeping more with its eyes closed.
- Perching low, or sitting on the cage floor for long periods.
- Less singing, chattering or interest in its surroundings.
- Laboured breathing: open beak, wheezing, a tail that bobs with each breath.
- Discharge from the nostrils or eyes, matted feathers around them.
- Eating or drinking more or less than usual, regurgitation.
- Loss of balance, falling off the perch, drooping wings.
Reading the droppings
A bird’s dropping has three parts: the faeces (the formed green or brown part), the urates (the white part) and the urine (the clear liquid). According to VCA, a healthy bird produces one roughly every 20 to 30 minutes.
- Fewer droppings
- A sign it is eating less: take it seriously, according to VCA.
- Faeces
- Soft or unformed, black, red or with blood, or containing undigested seed: abnormal.
- Urates
- They should stay white; bright yellow, green or pink urates are abnormal, according to an avian vet writing for the World Parrot Trust.
- Urine
- Much more of it over a lasting period, especially if the bird is drinking more: tell your vet.
- Soiled feathers around the vent
- A sign of diarrhoea or a digestive problem.
Newspaper or kitchen roll on the cage floor, changed every day, makes the droppings easy to check.
Common problems in budgies
- Scaly face and leg mites
- Common in budgies according to the MSD Manual: dry, white crusts on the beak, face and legs, often without itching. The beak can become permanently deformed if treatment is delayed.
- Goitre
- On a seed diet low in iodine, the thyroid enlarges and gets in the way of breathing: wheezing, “clicking” sounds, according to the veterinary edition of the MSD Manual.
- Kitchen fumes
- An overheated non-stick pan gives off fumes that can kill a bird with no other warning, according to the veterinary edition of the MSD Manual: keep your budgie well away from the kitchen.
The scales, an early warning
A significant change in weight, up or down, is among the signs of illness listed by VCA. In a World Parrot Trust publication, an avian vet advises weighing your bird about once a week on scales accurate to the gram. In a budgie of around 35 g, losing just a few grams already matters.
When to go to the vet
Note what changes, day by day
The signs of a sick budgie are subtle and build up over several days. In the MyArk health record, the household notes what it sees, the date and the weigh-ins, so your vet has an accurate history.
- Dated observations in the health record
- Weigh-ins on a chart in the weight tracker, to spot a drop early
- Vet visits and treatments kept in one place
- Your vet’s contact details on the pet sitter sheet
Common questions
How can I tell if my budgie is ill?
The most common signs: fluffed-up feathers, a puffed-up bird sleeping a lot, perching low or on the cage floor, less singing, laboured breathing, abnormal droppings, poorer appetite. As budgies hide illness, the slightest change in behaviour counts.
Why is my budgie fluffed up?
A budgie that sits fluffed up during the day, sleeps a lot and moves little is showing one of the most common signs of illness. See your vet promptly.
My budgie stays on the cage floor: is it serious?
Yes, it is a warning sign: a budgie that no longer perches is often weak. Contact your vet the same day.
My budgie’s tail bobs when it breathes: what should I do?
A tail that bobs with every breath shows that breathing is an effort. Have it checked without delay.
What does a normal budgie dropping look like?
A formed green or brown part, a white part (the urates) and a little clear liquid, roughly every 20 to 30 minutes according to VCA. Fewer, watery, black or red droppings, or coloured urates, are abnormal.
My budgie has crusts on its beak: what is it?
Often scaly face and leg mites, common in budgies according to the MSD Manual. Your vet will confirm the diagnosis and prescribe treatment; don’t wait, as the beak can become deformed.
