Why Do Cockatiels Eat Their Poop? The Real Reasons Explained
If you've just watched your cockatiel eat its own droppings, your first reaction was probably alarm. It's one of those behaviours that looks obviously wrong. But the answer to why it happens is more nuanced than it first appears — and it connects directly to cockatiel bird food. In some cases, a cockatiel eating its droppings is a completely natural behaviour with a biological explanation. In others, it's a signal that something is missing from the diet — particularly when owners wonder whether things like 'can cockatiels eat rice' are safe, but haven't yet filled in the nutritional gaps that matter most.
This guide
walks through every reason a cockatiel eats its droppings — from the entirely
normal to the genuinely concerning — and tells you clearly what to do in each
case.

Quick answer:
There are five main reasons cockatiels eat their droppings. Three are normal or explainable. Two are warning signs. This guide covers all five — and gives you a reference table so you can identify which situation you are dealing with.
1. Cecotropes — The Droppings That Are Meant to Be Eaten
This is the
most important thing most cockatiel guides leave out entirely: not all bird
droppings are the same, and some of them are biologically intended to be
re-ingested.
Cockatiels,
like many birds, produce two types of droppings. The regular droppings you see
coating the cage floor are waste. But they also periodically produce cecotropes
— softer, nutrient-dense droppings that are produced in the cecum and contain
partially digested matter, vitamins produced by gut bacteria (particularly B
vitamins and Vitamin K), and beneficial microbial content.
What cecotropes look like:
Cecotropes are softer and darker than regular droppings. They are sometimes described as looking like a cluster of small dark pellets or slightly mushy and darker than the bird's normal droppings. They are often consumed immediately after production — which is why many owners never see them at all, but observe the behaviour of the bird eating from near its vent area.
When a
cockatiel eats a cecotrope, it is not doing something pathological. It is doing
something biologically programmed — recovering nutrients that the digestive
system did not fully extract on the first pass.
Is this normal?
Yes. Cecotrope consumption is a normal, healthy behaviour in cockatiels. No intervention needed. If the bird occasionally reaches toward its vent area and appears to consume something, and otherwise appears healthy, this is almost certainly what you are observing.
2. Nutritional Deficiency — The Most Common Concerning Cause
If a cockatiel
is eating regular droppings — not cecotropes — with any frequency, the first
place to look is the diet.
A bird on a
seeds-only or nutritionally inadequate diet is chronically deficient in
multiple vitamins and minerals. The gut recognises this and, in an attempt to
recover whatever nutrition is available, drives the bird to consume its
droppings where some residual nutritional value may remain. It is not
irrational — it is a desperation response to genuine deficiency.
What is missing from a seeds-only diet
•
Vitamin A: Almost entirely absent from seeds. Critical for mucous
membrane integrity, immune function, and healthy digestive tract lining.
•
Vitamin D3: Birds in indoor environments with limited natural light
cannot synthesise adequate D3. Seeds provide none.
•
Calcium: Seeds are high in phosphorus and low in calcium — the
ratio actively impairs calcium absorption even when calcium is present
elsewhere.
•
B vitamins: A seeds-only diet is deficient in the full B-complex. B
vitamins are produced in part by gut bacteria — a compromised gut flora (from
poor diet) means both less production and less absorption.
The connection
to commonly searched questions like whether cockatiels can eat rice is worth
addressing here. Plain cooked rice is not harmful to cockatiels — it is
digestible and fine as an occasional soft food. But it contributes little
nutritionally and does nothing to address the deficiencies that drive
coprophagic behaviour. The foods that actually matter are dark leafy greens for
Vitamin A, cuttlebone for calcium, and pellets for balanced B-vitamin and
mineral intake.
Diet correction steps:
1. Introduce a quality pelleted diet — pellets provide balanced nutrition that seeds cannot 2. Offer dark leafy greens and orange-yellow vegetables at least 4 times per week 3. Keep cuttlebone available at all times for calcium 4. Reduce or eliminate sunflower seeds — high fat, nutritionally poor 5. Give the change 4 to 6 weeks — nutritional deficiencies do not resolve overnight
3. Gut Flora Disruption
A less
discussed but legitimate cause of coprophagy in cockatiels is disruption to the
gut microbiome — the community of beneficial bacteria that inhabit the
digestive tract and play a critical role in nutrient production and absorption.
Gut flora can
be disrupted by:
•
Antibiotic treatment: Antibiotics do not distinguish between harmful bacteria
and beneficial gut flora. A course of antibiotics, even a correctly prescribed
and completed one, leaves the gut flora depleted.
•
Prolonged poor diet: The microbiome is shaped by what the bird eats. A
seeds-only diet selects for a different (and less nutritionally supportive) gut
flora than a varied diet.
•
Stress: Chronic stress alters gut motility and the environment in
which gut bacteria thrive.
When the gut
flora is depleted, the bird may consume droppings in an attempt to re-inoculate
its gut with beneficial bacteria — similar in concept to why humans are
recommended probiotics after a course of antibiotics.
4. Boredom, Stress, and Redirected Behaviour
Cockatiels are
cognitively active animals. When they lack adequate mental stimulation, they
develop substitute behaviours — and those behaviours are not always benign.
Feather plucking, repetitive pacing, and occasionally coprophagy can all emerge
from the same root cause: an understimulated bird with insufficient outlet for
natural behaviour.
This is more
likely to be the cause when:
•
The bird is kept alone with
limited human interaction
•
There are few or no toys in
the cage
•
The bird has limited
out-of-cage time
•
The bird's daily routine is
minimal or unchanging
•
The behaviour appeared or
increased during a period of change or isolation
In this case,
addressing the enrichment deficit is the primary intervention. Introducing
foraging toys, rotating enrichment items, increasing daily interaction time,
and providing out-of-cage exploration opportunities will typically reduce or
eliminate boredom-driven coprophagy.
5. Chick and Parent Behaviour — Normal and Necessary
If you are
observing this behaviour in the context of a breeding pair or parent birds
raising chicks, there is a high probability that what you are seeing is
entirely normal parenting behaviour.
Parent birds consuming chick droppings
This is
standard nest hygiene. In the wild, accumulated droppings in a nest attract
predators and create a disease environment. Parent birds routinely consume
their chicks' droppings to keep the nest clean. This is not nutritional — it is
hygienic and survival-driven.
Chicks consuming droppings
Young chicks in
their first weeks sometimes sample droppings — their own or a parent's. This is
believed to serve a gut flora inoculation function: the chick's digestive
system is establishing its microbiome, and consuming the parent's droppings
introduces beneficial bacteria.
Is this normal?
Yes, in a breeding/chick context. Do not intervene. Parent birds consuming chick droppings are performing normal nest hygiene. Chicks sampling droppings in early weeks are establishing gut flora. Neither behaviour warrants concern in this context.
6. Illness or Parasitic Infection
Less commonly,
coprophagy in an adult bird with no obvious dietary or enrichment deficit can
indicate an underlying illness — particularly intestinal parasites or a
pathogen that is interfering with nutrient absorption.
When parasites
colonise the intestinal tract, they compete with the host for nutrients. The
bird, unable to absorb adequate nutrition from its food, may turn to its
droppings to recover what it can. The droppings themselves may contain visible
changes — unusual colour, consistency, or the presence of undigested food.
• Intestinal parasites: Roundworms, tapeworms — not common in captive cockatiels
but possible, particularly in birds that have had contact with wild birds or
outdoor environments.
•
Protozoal infection: Giardia and Trichomonas can both cause poor nutrient absorption
and drive compensatory behaviour including coprophagy.
•
Chronic infection: A low-grade bacterial or fungal infection of the
digestive tract can produce persistent malabsorption without dramatic visible
illness.
When to see the vet for coprophagy:
• Frequent, compulsive eating of regular droppings — not occasional • Droppings look abnormal — unusual colour, undigested food particles, watery • Bird has lost weight or appears in declining condition • Diet has already been improved and the behaviour persists after 4–6 weeks • Other symptoms present alongside — lethargy, reduced appetite, loose droppings • Bird has had recent contact with wild birds or an unknown source bird
7. Quick Reference — Situation, Cause, and Action
8. Is Coprophagy Dangerous for Your Cockatiel?
The answer
depends entirely on the cause and the type of dropping consumed.
Cecotropes — no risk
Cecotropes are
produced specifically for re-ingestion and do not pose a health risk. The
bird's system is designed for this.
Regular droppings occasionally — low risk in a
healthy bird
An occasional
sampling of a regular dropping by an otherwise healthy, well-nourished bird is
unlikely to cause harm. The digestive system of a healthy bird handles the
bacterial load without difficulty.
Frequent consumption of regular droppings — elevated
risk
Regular
droppings contain bacteria, bile salts, and metabolic waste products. Frequent
consumption of these, particularly in a bird with a compromised digestive
system, increases the bacterial load on the gut and can perpetuate or worsen
gut flora imbalance. It is also a symptom of something that needs addressing —
not the thing to focus on fixing directly.
Important:
Do not try to stop the behaviour directly — cover the droppings, use different cage liners, or discourage the bird. Address the underlying cause. Coprophagy is a symptom, not the problem. Preventing access to droppings without addressing the root cause produces an unsatisfied bird that finds other outlets for the same drive.
9. What to Do — A Step-by-Step Response
•
Step 1 — Identify which
type: Is the bird eating cecotropes
(soft, darker, from near the vent) or regular droppings from the cage floor? If
it's cecotropes, the behaviour is normal — stop here.
•
Step 2 — Assess the
diet: Is the bird on seeds only? When
were vegetables and pellets last offered? If the diet is inadequate, begin
improving it immediately and observe over 4 to 6 weeks.
•
Step 3 — Check
enrichment: Is the bird adequately
stimulated? Is it spending most of its time in an inactive cage with nothing to
do? If yes, introduce enrichment before drawing other conclusions.
•
Step 4 — Review recent
history: Has the bird recently had
antibiotics? Probiotics and diet improvement may help restore gut flora.
•
Step 5 — If behaviour
persists after diet and enrichment improvements: Veterinary visit. Bring a fresh dropping sample. A faecal
examination can rule out parasites and pathogens quickly.
• Step 6 — During the vet visit: Mention the behaviour specifically. Many owners are embarrassed to bring it up — vets are not surprised and it is clinically relevant information.
10. Diet — What Actually Helps
Since the most
common addressable cause of coprophagy is nutritional deficiency, here is a
practical summary of the dietary changes most likely to resolve it.
Foods to prioritise
•
Dark leafy greens: Spinach, coriander, curry leaves, fenugreek leaves — high
in Vitamin A, calcium, and B vitamins
•
Orange and yellow
vegetables: Carrot, pumpkin, sweet
potato, red capsicum — rich in beta-carotene for Vitamin A
•
Pellets: The most reliable way to deliver balanced vitamins and
minerals — introduce gradually if the bird is resistant
•
Cooked egg: High-quality protein and B vitamins — offer a small
amount weekly
•
Cuttlebone: Always available for calcium — essential for metabolic
function and gut health
On plain cooked rice
Plain cooked
rice is safe for cockatiels and can be offered as part of a varied soft food
rotation. It is easily digestible and a good vehicle for mixing with chopped
vegetables. It does not, however, address nutritional deficiencies on its own.
Think of it as a neutral carrier food — useful in combination with
nutrient-dense vegetables, not as a standalone offering.
Foods that make deficiency worse
•
Sunflower seeds in
excess: High fat, Vitamin A-poor,
addictive — birds often preferentially eat these and ignore other foods
•
Millet as a primary
food: Millet is a useful treat and
taming tool but nutritionally inadequate as a diet staple
•
Human processed food: Salt, sugar, preservatives — none are appropriate for
cockatiels and some cause active harm
FAQ
My cockatiel only does this occasionally and
otherwise seems healthy. Should I be concerned?
Occasional
sampling — particularly if the bird appears to be consuming cecotropes rather
than regular droppings, and is otherwise healthy, active, and eating normally —
is usually not a concern. The behaviour to watch for is frequent, compulsive
consumption of regular floor droppings, particularly in a bird on a poor diet
or with signs of weight loss or change in dropping appearance.
I improved the diet weeks ago and the behaviour
continues. What next?
If genuine
dietary improvement — not just adding a few vegetables, but transitioning to a
substantially better diet including pellets, greens, and varied food — has been
sustained for 4 to 6 weeks without change in the behaviour, the remaining likely
causes are gut flora disruption or an underlying illness. A vet visit with a
faecal sample is the appropriate next step.
Could my bird have got this behaviour from
watching another bird?
Cockatiels do
observe and learn behaviours from each other. If one bird in a multi-bird
household develops coprophagy for nutritional reasons, others may begin copying
the behaviour. In this situation, improving the diet of all birds
simultaneously is important — and identifying the original cause matters, as
another bird copying the behaviour does not mean all birds have the same
underlying issue.
Is it safe to handle my bird after it eats
droppings?
Normal hygiene
applies. Wash your hands after handling your bird as a general practice — this
applies regardless of the coprophagy question. Cockatiel droppings carry
bacteria that are generally not harmful to healthy adults but standard hygiene
is sensible.
Final Thoughts
The behaviour
looks alarming, but the explanation is almost always traceable and addressable.
In many cases it is entirely normal. In most of the cases that are not normal,
the cause is a diet that can be improved. The answer is rarely complicated — it
just requires knowing where to look.
If you are
unsure after working through this guide, the most productive step is a vet
visit with a fresh dropping sample. A faecal examination takes minutes and
removes most of the uncertainty quickly.
