How to spot signs of illness in a canary
Note any decrease in activity.
Canaries are active birds that enjoy flying around in their cages. If your canary has stopped flying or if they are spending long periods of time on their perch, you may want to take them to a vet.
A sick canary may tuck their head under their wings or sleep near their food bowl. Listen to the sounds that they make.
