Bird Droppings Color Changes — What They Mean

A bird's droppings consist of three components — feces (green/brown solid), urates (white/cream chalky portion), and urine (clear liquid) — and changes in any of them can signal liver disease, infection, dietary problems, or internal bleeding.

## Anatomy of Normal Bird Droppings

Normal droppings vary by diet but typically show: olive-green to dark green formed feces, white to cream urates, and a small amount of clear liquid urine. The ratio and appearance change significantly with diet — birds eating a lot of fruit will have wetter droppings.

## Color Changes and What They Indicate

Green Droppings
Bright lime-green feces suggest liver disease, bile pigment in the urine, or — in a bird that has not eaten — starvation stools where only bile is present.

Yellow or Lime Green Urates
Yellow urates (the white portion turning yellow or lime) indicate liver disease or kidney dysfunction affecting biliverdin metabolism. This is a significant finding.

Red or Brown Droppings
May indicate blood in the digestive tract, though certain red foods (beetroot, berries) can temporarily color droppings. Rule out diet before assuming pathology.

Black Tarry Droppings
Melena — digested blood from the upper gastrointestinal tract — produces black, tarry, foul-smelling droppings. This is a serious emergency.

White Chalky Urates in Excess
Chalky, gritty, or excessive urates can indicate dehydration or early kidney disease.

## Changes in Consistency

Watery Droppings (True Diarrhea vs. Polyuria)
True diarrhea involves unformed feces. Polyuria (excess water around otherwise normal droppings) is common with fruit-heavy diets, stress, or kidney disease.

Undigested Food in Droppings
Visible seeds or undigested food particles suggest malabsorption — a key sign of Proventricular Dilatation Disease (PDD) or gastrointestinal infection.
