Bird Droppings Colour Guide: What's Normal and What's Not
A bird droppings colour guide for owners: what normal faeces, urates and urine look like, which colours are harmless from food, and which mean see a vet now.
Health guide
Not a substitute for a vet. If your animal is unwell, in pain or getting worse, contact a qualified veterinarian straight away.
Quick answer
A normal bird dropping has three parts: a formed faecal part (usually green to brown), a white or creamy urate part, and a little clear liquid urine. Food and stress can change the colour and wetness for a day or so. Call an avian vet for black or tarry faeces, fresh blood, yellow or green urates, undigested seed, or any sudden change in a bird that is also fluffed up and quiet.
Why droppings matter
Birds hide illness by instinct. A sick bird can look nearly normal right up until it is seriously unwell, and droppings are one of the few early clues to what is going on inside. Learn what your bird's normal droppings look like and check them every morning. It is about the easiest health habit there is.
Put plain paper (newspaper, kraft or white paper) on the cage floor instead of coloured litter, so you can actually see the droppings.
The three parts of a dropping
Birds pass faeces, urates and urine together through a single opening, the vent.
| Part | Normal appearance | What it tells you |
|---|---|---|
| Faeces | Formed, tubular or coiled; green, olive or brown depending on diet | Digestion and diet |
| Urates | White, off-white or creamy; sits on or beside the faeces | Kidney function, hydration and liver health |
| Urine | Small clear liquid ring around the rest | Hydration and kidney function |
Size, shape and moisture differ with species and diet. Budgies and cockatiels pass small, fairly dry droppings. Lories and lorikeets eat nectar, so their droppings are normally very loose and watery. A pellet-fed parrot often has brown or tan faeces, where a seed-fed bird's are more likely to be green.
Colour guide: faeces
| Faecal colour | Common harmless reasons | When it may be a problem |
|---|---|---|
| Green to olive | Normal for many birds, especially on seed and greens | Very dark, bright or "grass" green with little faecal bulk can mean the bird is not eating and is passing bile |
| Brown or tan | Normal on pellet diets | Rarely a concern on its own |
| Red, orange or purple | Coloured pellets, berries, beetroot, pomegranate, red peppers | Red that looks like fresh blood, or appears without such foods |
| Black or tarry | Very dark berries can darken droppings | Black, tarry faeces can mean bleeding higher in the gut and need prompt attention |
| Pale, bulky, clay-coloured | Can point to digestive or pancreatic problems | |
| Undigested whole seed | Suggests a digestive problem; see a vet |
Colour guide: urates
Urates should be white or creamy. A change here often means more than a change in the faeces.
- Yellow urates: can be linked to liver problems, although some foods and vitamin supplements tint urates too.
- Lime-green or bright green urates: often go with liver disease or certain infections. This needs a vet.
- Brown or red urates: may mean blood or kidney problems, and sometimes lead or zinc poisoning from chewing metal. See a vet promptly.
- Chalky, dry, reduced urates with little urine: can be a sign of dehydration.
Wateriness and consistency
Extra urine (polyuria) and diarrhoea are different things. With polyuria the faecal part is still formed, just sitting in a big wet ring. Usual harmless causes:
- Lots of fruit, vegetables or wet food
- Bathing, or drinking more in hot weather
- Stress or excitement, such as a car ride or a trip to the vet
If it carries on for more than a day with no obvious reason, it can point to kidney disease, diabetes, infection or exposure to a toxin.
True diarrhoea means the faecal part itself is loose, unformed or soupy. Birds get it less often than mammals do, and in a bird it is more often a sign of illness.
Other changes to note:
- Mucus or slime in the droppings
- A strong, unusual smell (normal bird droppings barely smell)
- Fewer or much smaller droppings than usual, which can mean the bird is eating less
- One very large dropping first thing in the morning. This is normal in many birds after holding it overnight, and in females in breeding condition
A simple daily routine
- Change the cage paper at the same time every day.
- Look at the droppings before you clean: how many, how big, the colour of each part, how wet.
- Weigh your bird weekly on a gram scale, and more often if the droppings change.
- If something looks off, take a photo. A few days of photos helps a vet a lot.
- Think back over the last 24 hours: new foods, coloured treats, baths, stress, heat.
When to see a vet
Contact an avian vet the same day if you see:
- Fresh blood, red streaks or blood clots in the droppings or around the vent
- Black, tarry faeces without dark food to explain it
- Lime-green, yellow or brown urates
- Undigested whole seeds in the droppings
- Very small or no faeces, with mostly urine and urates (the bird may not be eating)
- Watery droppings for more than a day, or with other signs
- Any droppings change together with fluffing up, sleeping more, tail bobbing, reduced appetite, vomiting or sitting on the floor
- Straining, a pasted or dirty vent, or tissue protruding from the vent
The vet will usually examine the bird and may test a droppings sample (a faecal smear, Gram stain or parasite check, for example). Depending on what they find, they may suggest blood tests or X-rays. If your budgie has also gone off its food, read Budgie Not Eating: Causes and What to Do.
In Pakistan
Plenty of birds in Pakistan live on a mixed-seed diet plus seasonal fruit such as pomegranate, mango, jamun and watermelon. Jamun and pomegranate can stain droppings dark purple or red, and juicy summer fruit often makes droppings watery. Usually that is nothing to worry about. Birds drink more in hot weather and their droppings may look wetter, so keep the water fresh at all times. Old paint and metal fittings can contain lead or zinc, so check cages and toys from local markets for flaking paint or soft metal parts.
Keeping notes on your bird's droppings takes very little effort and can catch problems early. For more on a healthy routine, see The Complete Guide to Keeping Pet Birds, or browse healthy birds on Paalo.
Frequently asked questions
Why are my bird's droppings suddenly watery?
Extra urine (polyuria) is common after a lot of fruit or vegetables, after a bath, or when a bird is stressed, at the vet for example. If watery droppings go on for more than a day, or come with fluffing up or a poor appetite, see a vet.
Can food change the colour of bird poop?
Yes. Coloured pellets, berries, beetroot, pomegranate and similar foods can turn droppings red, purple, orange or green. Food colour usually shows in the faecal part and clears within a day or so once the food is stopped.
Should I take a dropping sample to the vet?
It helps. Put clean white paper on the cage floor the night before and bring a fresh sample, or a photo of several droppings, in a clean sealed container. Ask your vet how they like samples brought in.
