Best Pets for Small Apartments: Top Low-Maintenance & Friendly Choices
1. What Does a Healthy Bird Look Like?
Before you can spot illness, it helps to know what’s normal.
A healthy bird has:
- Bright, alert eyes
- Clean feathers that sit smoothly
- Clear nostrils (no discharge)
- Active behavior (singing, chirping, flying)
- Regular eating and drinking
- Normal droppings (green/brown with white)
2. Why Do Birds Hide Illness?
In the wild, a weak or sick bird becomes easy prey. So birds are good at hiding signs of being unwell.
This makes it hard for owners to notice early symptoms. That’s why daily observation is important.
3. Common Signs of Illness in Pet Birds
Watch closely for these general warning signs:
- Fluffed-up feathers all day
- Sitting still or sleepy more than usual
- Loss of appetite
- Change in droppings
- Sudden weight loss
- Weakness or trouble perching
- No interest in playing or flying
These signs may seem small but can mean something serious.
4. Behavioral Changes in Sick Birds
A change in behavior is often the first sign.
Look out for:
- Hiding in a corner of the cage
- Less chirping or singing
- Biting or sudden aggression
- Not responding to your voice or movement
- Not grooming or preening feathers
Behavioral changes are easy to miss but very important.
5. Physical Symptoms to Watch For
Physical signs are easier to spot if you check your bird daily.
Common signs:
- Drooping wings
- Swollen or crusty eyes
- Discharge from nose or beak
- Dirty feathers around vent (bottom)
- Bald patches or constant scratching
- Lumps or swelling on the body
If you see any of these, call a vet.
6. Breathing Problems in Birds
Birds have delicate lungs and can easily get respiratory infections.
Breathing trouble signs:
- Tail bobbing with each breath
- Open-mouth breathing
- Wheezing or clicking sounds
- Sneezing a lot
- Nasal discharge
If your bird is struggling to breathe, it’s an emergency.
7. Droppings and Digestive Issues
Your bird’s poop tells a lot about their health.
Normal droppings:
- Green/brown solid part
- White urate
- Clear liquid
Warning signs in droppings:
- Watery or runny poop (diarrhea)
- Red, black, or yellow color
- No poop at all

Check droppings daily for changes in color, smell, or texture.
