SYMPTOMS OF TUBERCULOSIS IN BIRDS.
In the gallinaceæ there may be inappetence, vomiting, diarrhœa, with hurried breathing, sneezing, and the general phenomena of debility, weakness, advancing emaciation and anæmia, the comb and wattles becoming pale and flaccid and the visible mucosæ bloodless. The eyes are sunken and lack lustre, the head sinks, the wings and tail droop, and weight is steadily lost. When the bones and joints of the legs and wings are involved the local swellings and distortions are visible indications of the trouble.
In parrots these local swellings and particularly the horn-covered vegetations on the face and around the beak are characteristic.
Canary. Tuberculosis is common in the canary, contracted, as in the parrot, from man, with whom alone the caged bird comes into dangerous contact. The interchange of the disease between pet birds and their owners would demand the exclusion of such from the rooms of consumptives, and a careful watch for indications of disease of the air passages with marasmus, that the bird may be disposed of before it has become a source of danger.
