Which body language signs mean a bird is sick?
These outrank every other cue on this page, and any sound your bird makes.
Go to an avian vet or emergency clinic now
- Tail bobbing with each breath, beak open while resting, or the neck stretched to breathe
- Huddled, weak, or sitting low or on the cage floor
- Off balance or falling
- Bleeding that does not stop
- Straining, a swollen belly, or tissue showing from the vent
- Panting, with feet and beak that feel hot
Here is what to do on the way.

Call your avian vet now
- Fluffed up for long periods, sleeping more with eyes closed, less active or less interested
- Head shaking, rubbing the beak on cage objects, yawning, sneezing or runny nostrils
- A drooping wing, or a leg your bird will not use, after a crash or fall: see an avian vet within a day (our own timing)
Birds hide illness, so body language never proves a bird is well. Healthy birds are bright and alert with clear eyes, but a sick bird can look that way for a while.

What does parrot body language mean?
The cues with a qualifying source, and how strong that source is.
What does a cockatiel’s crest mean?
One university species account describes it like this. Upright: alert or startled. At about 45 degrees: content. Flat: agitated or threatened.
Evidence: moderate. One account, cockatiels only. Do not apply it to other crested birds.
Source: Animal Diversity Web, University of Michigan, Nymphicus hollandicus
What do courtship displays look like?
Male cockatiel: a strut, wings held out from the body, rapid beak pounding. Female cockatiel: muffled peeps with the tail held up. Female canary: a crouch with an arched back and vibrating wings.
Evidence: moderate for cockatiels, from one account. Peer-reviewed for canaries.

Why does my parrot grind its beak?
One welfare body lists beak grinding or clicking, with fluffed facial feathers and then preening, as a sign of contentment. We found no qualifying source for it as a sleep signal.
Evidence: weak. One welfare body. A click that repeats with each breath is a different thing: see clicking sounds.

Why does my bird regurgitate on me?
Regurgitating to a mirror, a toy or a person can be courtship. Throwing up food can also be a sign of illness. If your bird looks unwell, or it is new and you are not sure, call your avian vet.

How does handling change behavior?
Restraint raises stress hormones in cockatiels and other parrots, and studies saw more reactive behavior and inactivity afterward. So what you see right after toweling is not your bird’s normal. Let your bird rest somewhere quiet. Breathing should settle within 3 to 4 minutes of being let go. If open-beak breathing or tail bobbing goes on after that, it is an emergency.

What about pacing or rocking?
The AAV says a bird that repeatedly paces, bobs the head, rocks, swings the head or body, or spins should be examined by a vet.

What does eye pinning mean?
Owners use “eye pinning” for a pupil that quickly shrinks and widens. We looked and found no qualifying veterinary or peer-reviewed source for what it means. So we will not tell you it means excitement, aggression or anything else, and ParrotSense does not use it. The app’s eye options are simply open and bright, or half-closed and sleepy.
The same goes for these popular cues. We found no qualifying source for them, and the app does not use them:
- Freezing, sleeked feathers or a fixed stare as alarm signs
- Head bobbing or wing quivering as begging signs
- Beak grinding as a sleep signal
- A meaning for hissing or tongue clicking. If you hear a hiss, check whether it could be breathing.
No source found does not prove a cue is wrong. It means we will not build advice on it. If you notice one, note what was happening and look at the whole bird.
Look-alikes
What looks like a problem but may not be?
- Fluffed. Normal when cool, but not for long.
- On the floor. Some birds like to forage there, especially cockatiels, cockatoos and African greys. A bright, busy bird is not the same as one sitting low.
- Wings held out. A strutting male cockatiel may be courting. A still bird with wings away from the body, or one that pants, may be too hot. Lower the heat. If the feet and beak feel hot too, it is an emergency.
- Rapid sniffing. Pionus parrots often do this when stressed.
- Sleeping on the bars. Small parrots may sleep hanging on the side of the cage.
None of these cancels an illness sign. Not sure? Do not wait and see. Call your avian vet.

- Add breathing, feathers, posture, eyes, crest, activity and body to a recording
- Emergency options are marked, and a fixed warning shows as soon as you pick one
- The crest options say “in cockatiels,” because that is where the evidence is
- Beak grinding is treated as weak evidence, and confidence stays low
- Eye pinning is not on the list
