Beak grinding
Happy / CalmQuiet rasping clicks made by sliding the upper and lower beak halves together. Almost always done with eyes half-closed, on a favourite perch, just before sleep.
What to do
Nothing — this is the avian equivalent of a contented sigh. Cover the cage and let them rest.
Stretch — one wing & one leg
Happy / CalmBird extends one wing and the leg on the same side fully out, then folds back. Sometimes both sides in sequence. Done after a long perch session or just after waking.
What to do
Healthy, relaxed body language. No action needed.
Allopreening (mutual grooming)
Happy / CalmTwo bonded birds gently nibble each other's head and neck feathers — places they cannot reach themselves. Pure bonding behaviour.
What to do
Leave them alone — this strengthens the pair bond. A bird preening your eyelashes is showing the same trust.
One foot up, feathers slightly fluffed
Happy / CalmBird stands relaxed on one foot with the other tucked into chest feathers, body slightly puffed for warmth. Eyes may blink slowly.
What to do
Resting normally. Persistent fluffing for hours plus closed eyes during the day is a different story (see "persistently fluffed").
Soft chirps to you when you walk in
Happy / CalmQuiet, rhythmic chirping or a flock-call whistle when the bird sees its bonded human enter the room.
What to do
Greet back. This is a contact call — answering it builds trust.
Eye pinning / flashing
ExcitedThe pupil rapidly contracts and dilates. Combined with a relaxed posture it means intense interest. Combined with raised feathers and a held-back beak it means agitation.
What to do
Read the rest of the body. Pinning + slick feathers = curious, fine to engage. Pinning + fanned tail + leaned forward = back off, a bite is coming.
Crest raised (cockatiels, cockatoos)
ExcitedCrest feathers stand straight up. Triggered by surprise, novelty, or excitement — a new toy, an unfamiliar visitor, a sudden noise.
What to do
Give the bird a few seconds to assess. If the crest stays up rigidly with a hiss, don't reach in.
Crest flat against head
Happy / CalmCrest pressed flat. Context-dependent — usually it means deeply relaxed, but combined with crouched posture and pinned eyes it is fear.
What to do
Look at the body too. Flat crest + relaxed body + half-closed eyes is calm. Flat crest + leaned-back body + wide eyes is fear.
Foot lifted toward you
ExcitedBird lifts a foot in your direction, sometimes opening and closing the toes. The classic step-up invitation, or a request to play with your hand.
What to do
Offer a finger or perch at chest height. If the bird steps up gently, you've been invited.
Pinned eyes + bobbing + dilated pupils
ExcitedRapid eye-pinning, head bobbing, beak slightly open, body coiled. The bird is either thrilled or about to bite — and the difference is razor thin.
What to do
Stop reaching in. Pull your hand back, lower your voice, give the bird thirty seconds to settle before trying again.
Head bobbing (regurgitation)
HormonalRepeated up-and-down head pumping, sometimes followed by bringing up food onto a favourite perch, mirror, or person. Courtship behaviour.
What to do
It's flattering — the bird thinks of you as a mate. Don't encourage it: redirect with a foraging toy, reduce daylight to 10 hrs, and avoid petting below the neck.
Quivering wings
HormonalHalf-open wings shaken rapidly. In adults it is a courtship display; in juveniles it is a begging request to a parent or to you.
What to do
Juvenile begging — fine, ignore it once the bird is weaned. Adult quivering plus regurgitation = full hormonal mode; cool the bonding behaviour and reduce light hours.
Tail fanning
HormonalTail spread wide like a fan, often with raised back feathers and strutting. Display behaviour — courtship in some species, aggression in amazons.
What to do
Don't engage. Step back, dim the lights, and avoid touching the bird until the display ends. Amazon owners — keep hands well clear; bites are likely.
Regurgitating food onto you
HormonalBird coughs up softened food and offers it. In the wild this is mate-feeding — to a bonded partner during courtship.
What to do
Quietly accept it (don't recoil — it is a compliment), then put the bird back without praise. Don't encourage repeat by petting after.
Beak clacking
WarningTwo or three sharp clicks of the beak halves. Different to grinding — louder, single events, with a stiff body.
What to do
Verbal warning. Step back; the bird is asking for space. Approach again in a minute, calmer, lower hand.
Hissing
WarningOpen-beaked air hiss, often with a slight sway and raised crest or back feathers. Common in cockatiels and cockatoos protecting nest or perch.
What to do
Do not reach in. Hens on eggs hiss to defend the clutch — let her be. For non-nesting hisses, give space and try again later.
Beak open + leaned forward
WarningBeak gaping, body leaned in your direction, feet braced. The classic pre-bite posture.
What to do
Pull your hand back immediately. Pushing through this almost always ends in a serious bite. Try again from a different angle in a minute.
Mantling over food or toy
WarningWings half-spread, body hunched over an object, eyes pinned. The bird is claiming the item against perceived theft.
What to do
Don't take the object away by force — wait it out, or trade for a higher-value treat. Removing by force teaches the bird to bite first next time.
Feathers fluffed persistently for hours
SickFeathers stay puffed all day, not just briefly. Bird sits low on the perch, sometimes with eyes half-closed mid-day. Often paired with reduced food intake.
What to do
Treat as urgent. Birds hide illness until critical — schedule a vet visit today, increase warmth (around 28°C / 82°F), and weigh the bird daily.
Wing drooping (one or both wings)
SickWings hang lower than usual. One wing only can mean injury or break. Both wings briefly is overheating; both wings persistently is illness or exhaustion.
What to do
One wing = avian vet today; suspect a fracture. Both wings + open beak + panting = move bird out of heat, offer cool water. Both wings persistently = vet.
Tail bobbing with each breath
SickVisible up-and-down pumping of the tail in time with breathing. Indicates laboured respiration — a serious sign in any species.
What to do
Avian emergency. Get to a vet today, do not wait. Respiratory illness in birds progresses to fatal within 24–48 hours.
Feathers tight against body
SickFeathers slicked down hard, body tense and slim, often with wide eyes. Two causes: acute fear (briefly), or end-stage illness (persistently).
What to do
If brief and there is an obvious trigger (loud noise, new pet) it's fear — calm voice and time will fix it. If persistent with no trigger, vet today.
Sitting on cage floor
SickA normally perching bird sitting on the cage floor for extended periods. Sometimes with eyes closed or feathers fluffed.
What to do
Concerning unless the bird is a nesting hen. Otherwise treat as a strong illness sign — vet visit today, keep warm, monitor weight.
Body language is always context-dependent — read the whole bird, not just one signal. When in doubt about an illness sign, an avian vet visit is always cheaper than waiting too long.

Why birds are harder to read than dogs
Dogs evolved alongside humans for 30,000 years — their body language has been selected specifically to communicate clearly to people. Parrots have lived alongside us for at most a few hundred years, and prey species evolved to hide weakness from predators. The result is a communication system that is rich, but coded in subtle ways most owners never learn to read.
The biggest single mistake new bird owners make is reading a single signal in isolation. Eye pinning alone tells you nothing — you need the feather position, the head tilt, the distance from the cage, the tail set, and the vocal tone all together. The cards above pair each signal with the most common context, but every individual bird builds its own dialect with you over time.
One rule never bends: birds hide illness until it is severe. Persistently fluffed feathers, sitting on the cage floor, tail bobbing with each breath — treat any of these as a same-day avian-vet visit. Waiting until tomorrow is the most common reason birds die from otherwise treatable conditions.
