When I first began working with birds in zoo collections, older keepers warned me about respiratory ailments such as “Bird Breeder’s Lung” and “Poultry Worker’s Disease”. Several of my co-workers were always short of breath and coughed frequently. Eventually, some were diagnosed with Hypersensitivity Pneumonitis (a/k/a Extrinsic Allergic Alveolitis), which results from inhaling organic dust and other irritating substances. Private bird owners are also sometimes afflicted with this condition, and birds themselves may sicken and die when exposed to certain common airborne particles and chemicals. Unfortunately, advertisements for air-cleaning devices have confused rather than clarified the options available to us; some are actually harmful (yet still on the market!) while others are highly effective.

The hazards of second-hand cigarette, cigar and pipe smoke to non-smokers have been well-accepted for years. As many have expected, these health concerns extend to the lungs and hearts of pets exposed to smoke as well. New evidence, however, indicates that nicotine may be harmful not only to bird respiratory systems, but also to their skin.
Birds are especially sensitive to airborne toxins…so much so that canaries and other species long played a vital role in warning workers of the presence of poisonous gases in underground mines (the birds weakened and died long before the fumes affected the miners). It is, therefore, not surprising that veterinarians have documented a high frequency of respiratory disorders and eye irritations among birds kept by owners who smoke indoors.
However, it has also become apparent that problems of a different nature are also affecting birds owned by smokers, even when the birds are never exposed to second-hand smoke.
Nicotine on the Skin and Feathers
Nicotine is readily absorbed through the skin of some animals and clings to hair, fur and feathers. In the course of working with amphibians in zoos, I’ve been made aware of many frog and salamander deaths that occurred, often instantaneously, after the animals were handled by someone who had smoked and not washed well afterwards. It now seems clear that nicotine lingering on fingers also causes dermatitis and other skin afflictions in pet birds, and may lead to their deaths.
Birds with nicotine-stained skin often pick at their feathers, nibble on their feet and otherwise exhibit signs of discomfort. Dermatitis often follows, with small sores or areas of eroded skin developing. Birds so afflicted will pick at these areas and the scabs that form, opening an avenue of attack for opportunistic bacteria and fungi. These micro-organisms (which are always present in the environment) can cause severe and potentially fatal infections.
