Canary singing less or stopped: health causes

A canary that has stopped singing — or sings significantly less than usual — is telling you something important. Canaries are bred for vocalisation; a silent canary is rarely a happy, healthy one.

Normal reasons for reduced singing

- Moulting — the most common reason. Canaries moult annually (usually late summer to autumn) and almost universally go quiet during this period. The feather replacement process is physiologically demanding; singing reduces and resumes fully when moulting is complete (typically 6–8 weeks). You may also notice the bird looking scruffy during this time — this is normal.
- Short days / reduced light — canary song is triggered by light. In winter or in rooms without sufficient natural light, singing decreases. A full-spectrum bird lamp (12–14 hours of light daily) can encourage singing year-round.
- New environment or stress — a recently moved cage, new household members, or changes in routine cause temporary silence.
- Social isolation or boredom — canaries kept without visual/auditory contact with other birds may sing less. Placing the cage where the bird can hear other birds (including audio recordings) sometimes helps.

Health causes that must be ruled out

If a canary has stopped singing abruptly and there is no obvious moult or environmental change:

- Respiratory infection — air sac mites (Sternostoma tracheacolum) infest the airways and trachea, causing laboured breathing, a squeaking or clicking sound when the bird breathes, and cessation of song. Classic in canaries, especially those recently purchased. Diagnosis requires a vet examination. Treatment: ivermectin or other parasiticides, very effective when caught early.
- Syrinx (voice box) infection or injury — the syrinx is the canary's vocal organ; any infection or trauma affecting it silences the bird.
- Bacterial or fungal respiratory infection — aspergillosis, Mycoplasma, or bacterial infection in the airways.
- General illness or pain — a sick or painful bird stops singing as one of the first behavioural changes. Check for: fluffed feathers, sitting on the floor, weight loss, change in droppings.

What to check at home

Hold the bird gently (a slight squeeze to the sternum) and listen close to the chest for any clicking or wheezing sounds not audible from a distance. This indicates air sac mite disease — see an avian vet.
