My vet has a little canary in a cage in his office. I'm quite sure the bird is lonely - I would be too if I was him. When I've mentioned this to my vet he says 'no, the bird is fine.' And I understand from staff that he says if they bring another bird the canary would stop singing (as he does all day.) A friend of mine told me birds sing in cages when they are lonely, so . . . I'm just trying to find information on birds and how they should be with a friend. Any suggestions?
