That Bird Blog – Bird Care and History for Pet Birds

Parrots use a wide range of postures when communicating with one another and with their owners.  Understanding the meaning of your parrot’s body language will simplify interactions with your pet, and is also important in assessing its health.  Today we’ll look at puffed feathers – a behavior which can have several very different meanings, and so must be judged in the context of the surrounding circumstances.

Temperature

Parrots, and all birds for that matter, puff up their feathers in an effort to keep warm.  The layer of air trapped within the feathers and warmed by the parrot’s body provides amazingly effective insulation.  If you watch native birds during cold weather, you can readily observe this behavior.  A bird’s internal temperature is much higher than our own, averaging 106-110 F, and so many species (but only a few parrots!) easily tolerate frigid weather.

Puffed feathers can, oddly enough, also indicate that your parrot is too warm.  In this case, the feathers may be flared to a greater degree than when cold temperatures are involved, and the wings may be held out a bit from the body.  When very hot, the parrot may open its beak and pump the throat rapidly, a behavior known as gular flapping.

Aggression

Like many animals, parrots that feel threatened will attempt to make themselves appear larger…flaring their feathers and sometimes spreading the wings.  The head feathers may be raised quite high, even among species without crests (the “head display kings” are the cockatoos and hawk headed parrots; please see photo).  Aggressive parrots will also stare at the threat – you may notice the eye’s pupil widening as well – and may snap their beaks or scream.

A normally friendly bird that suddenly begins exhibiting this behavior, especially if it does so as you approach, may be masking an injury.  Anticipating pain, the bird is warning you off and so should be checked carefully.  Sudden aggression may also arise as a result of hormonal changes associated with sexual maturity, or because the bird is jealous of attention being given its favorite person by another pet or individual.

Sickness

Sick or injured parrots, and females having difficulty passing eggs, will sit, sometimes on the cage floor, with their feathers puffed out and the body held in a “hunched” position.  The eyes may be closed or partially closed as well.  As it is in a bird’s “best interests” to hide any symptoms of illness (predators single out sick and injured individuals as prey), parrots exhibiting such dramatic signs of illness should be seen by a veterinarian right away.

Parrots that pair up well, mate, hatch eggs and feed their chicks are every bird-breeders dream.  However, some such birds present us with a frustrating situation – just as the chicks begin to grow feathers, one or both of the otherwise doting parents begin to pluck at their chicks’ feathers.  Bleeding and skin bruising follow, and, while the chicks usually recover, they are often left high-strung and nervous.  Chicks housed in outdoor aviaries may suffer from exposure and chilling as well.

The Scenario

Chick-plucking is most commonly observed among peach-faced lovebirds, budgerigars and cockatiels (particularly lutino cockatiels).  Attacks on the plumage usually commence when the feathers first emerge from the skin, and may continue until the time they unfurl.  Oddly, the erring adults continue to feed their offspring throughout, and remain good parents once the plucking ceases.

Unfortunately, chick-plucking parents usually do not change, and subsequent offspring are usually attacked as well; there is also evidence that chicks born to “plucking parents” repeat the cycle when they mature and reproduce.

A Theory

The most likely explanation for this perplexing behavior is that it results from frustrated attempts by the parents to preen the emerging feathers.  Unable to perform this task properly on the thin, unfurled plumage, the anxious parents begin pulling at the feathers.  The fact that most attacks are confined to the chicks’ napes and upper wings – areas not reachable by the chicks and usually attended to by the parents, lends support to this theory.

Thwarting Attacks

Bitter Apple Spray is often successful in deterring plumage attacks, but is best applied before plucking begins.  If the chick’s skin is broken, consult your veterinarian before applying Bitter Apple or similar products.

In caring for birds at home and in zoos, I have found that having emergency care items on hand has often prevented minor mishaps from turning into disasters.  Supplements that aid in preventative health care are also essential.  Today I have assembled a list of products that parallel those used in public aviaries, and which should be every private bird keeper’s possession.

Bird First Aid Kit

The VSI Bird First Aid Kit is stocked with powdered styptic, bandages, antiseptic wipes, forceps and many other useful products, this kit has everything you need to deal with minor emergencies.  The emergency card included in the kit is most helpful.

Nutritional Supplements

Lafeber Powdered Vitamins can be used on a daily basis, and are especially useful in that they can be applied to food or water.

Virbac Vita Flight Supplement is flavored with fruit and therefore well-accepted by many birds.  It is designed for use during stressful times, such as when a bird has been re-located or is molting, breeding or recovering from an illness.  Another of Virbac’s products, Ornabac, is fortified with extra Vitamin B, an important nutrient during especially stressful events.

Feather and Skin Care

Feather Glo Bird Bath helps to keep both skin and feathers in good shape, while Feather Brite Bird Bath Spray contains lanolin and aloe to assist in soothing irritated skin.

Scalex Mite and Lice Spray should always be on hand to address external parasites.

Bitter Apple has long been favored as a means of discouraging feather plucking.  It is most effective when applied as soon as plucking commences, and therefore should always be on hand.

Beak Conditioning

Disguised as an attractive toy, the volcanic pumice in Four Paws’ Pumice Kabob is one of the most effective materials for keeping bird beaks naturally trimmed and in prime condition.

Swollen areas and assorted growths are regularly seen on the otherwise hearty budgerigars (parakeets) and, less commonly, on other parrots, finches and softbills. Ranging from harmless to quite serious, these typically arise from trauma, abscesses, tumors, ruptured air sacs, hernias, cysts or egg-binding, but other -less obvious maladies may also be at work.

A Caution

The following remarks, while written with budgerigars in mind, are applicable to all types of birds. Please note that they are provided as guidelines, to help you understand what might be happening… only a veterinarian can accurately diagnose your bird’s medical problems.

Even benign growths, if accompanied by shivering, loss of appetite, breathing difficulties or similar symptoms, are cause for concern and necessitate an immediate visit to your veterinarian.

Ruptured Air Sacs

Budgerigars and other birds may rupture air sacs by flying into windows or other obstacles during their time out of the cage. Bird-proofing flight rooms and gradually adjusting your pet to such will go a long way in alleviating this problem. Less commonly, air sacs may be damaged when startled birds crash into cage bars or walls.

A swollen area along the breast, which emits a characteristic “crackling” sound when gently touched, is a sure sign of a ruptured air sac. Unless involving a huge area, air sac damage usually resolves quickly on its own.

Hematomas

Trauma-related injuries that do not involve air sacs may result in hematomas…swollen, blood-filled injuries below the skin (in people, such are often called “black-and-blues”, but skin color change will not usually be evident in a bird).

Resulting from broken blood vessels, the pooled blood typical of hematomas is usually re-absorbed by the bird without incident.

Abscesses

Avian abscesses present as swollen, painful, reddish areas that are warm to the touch. The swollen area, or abscess, is filled with white blood cells and other blood borne compounds produced by the bird to battle infection. The abscess usually also contains dead tissue and living and dead bacteria or other pathogens. Budgerigars often exhibit abscesses below the eye, but they may also occur on the feet, in the mouth and at other locations.

As a defense measure, the abscess has been walled off from the rest of the bird’s body, but the toxins and bacteria contained therein can escape and spread via the blood to vital organs. This can happen very quickly, and usually has fatal results. Therefore, all abscesses should be treated promptly by a veterinarian.

Gout, a disease that takes hold when uric acid is stored in the joints and internal organs, sometimes produces abscess-like growths on the feet of budgerigars. Known as tophi, these growths will bleed extensively if impacted or cut, and should be addressed by a veterinarian.

Tumors

Tumors are often difficult to identify specifically, and may arise from a wide variety of diseases and conditions. Fatty tumors are usually benign and require monitoring but no other treatment, while others may be malignant.

Any unusual growth or swelling that you notice should be examined by a veterinarian. A biopsy may be used to confirm the doctor’s diagnosis if there is any doubt as to the nature of the problem.

Next time we’ll complete our review of noxious bird bumps with a look at feather cysts and cloacal swellings. Until then, please write in with your questions and comments.

The possibility of a flea or mite infestation in one’s home is a very troubling concern…pet-owners’ fears about this have been the source of many distressed calls for assistance that I have received over the years. The good news for bird keepers is that external parasites are not all that common among our feathered friends, and most are very specific in their host preferences. The few that do crop up from time to time are of concern, but all can be eliminated fairly easily, especially if detected early.

The Daily Health Check
A careful daily check of your bird is the key to early detection of a parasite problem. This is particularly important if you keep several birds, have recently added a new individual to your collection, or have brought your bird to a pet store for wing or nail clipping.

Bear in mind that not all feather and skin abnormalities are caused by parasites – feather chewing, poor nutrition and viral, bacterial or fungal disease are all possibilities (and, indeed, more likely than parasitic infestation).

First Steps
If you do discover mites or lice, a good first line treatment is Scalex Mite and Lice Spray . While this pyrethrin-based medication is often successful in eliminating the invaders, a visit to your veterinarian for a positive ID of the species involved is important (also, secondary problems, such as bacterial infections, are often associated with parasites). As most parasite eggs are unaffected by medications, you’ll need to space out the application of the spray as directed in the instructions in order to eliminate the pests as they hatch.

Red Mites
Small Arachnids (spider and tick relatives) known as red mites, Dermanyssus gallinae and related species, are the most troublesome pests in terms of transmission to other pets and people. These mites are not choosy as to their host and, unlike most avian parasites, leave the bird at night to deposit eggs in perches, nests, furniture and rugs. They can be observed crawling about the afflicted bird at night, or attached to a white sheet that has been draped over the cage.

You veterinarian will likely use Ivermectin as a treatment; red mites feed upon blood, so tests for anemia and bacterial infection are also recommended.

You should consult with your doctor and a professional exterminator concerning how best to eliminate lice that might possibly have taken refuge in your home or if you observe any upon your skin.

Scaly Face Mite
The mite most commonly found on pet birds is scaly face mite, Knemidokptes pilae. It is almost entirely limited to budgerigars, only rarely afflicting other parrots or, less commonly, finches, and does not establish itself on other pets or people.

Scaly face mites are usually found around the cere (the area just above the beak), vent and legs. They burrow into theses areas, leaving tiny holes in the skin and a powdery plaque in their wake. As you can imagine, the unfortunate bird becomes extremely uncomfortable and scratches at the affected areas. In severe infestations, the bill itself may be damaged. The mites themselves are not visible to the naked eye.

In finches, a related mite tends to focus on the feet – birds so afflicted are said to have “tasselfoot”.

Mineral oil spread about the skin to suffocate the mites is often effective, but treatment with Ivermectin is preferable.

Air Sac Mites
Air sac mites remain within the respiratory tract and are most frequently seen in canaries and other finches. Birds parasitized by these mites usually breathe heavily, with their beaks wide open. Related species, termed tracheal mites, cause “gape mouth”, a condition seen in turacos and other species commonly kept in zoo collections.

Ivermectin is the drug of choice, but it must be administered carefully – a die-off of large numbers of mites at once can cause the host bird to suffocate.

Lice
Lice are parasitic insects. Less commonly seen in pet birds than mites, various types feed upon blood, feathers or skin. Some types concentrate at the bases of the feathers, while others attach to the feathers’ lower surfaces or the skin itself.

Nearly all lice are very specific as concerns host selection, feeding upon only one particular bird species. Bird lice will not attack people or other pets, and are sensitive to Scalex (pyrethrin spray) and Ivermectin. Because lice damage the skin, a veterinarian should be consulted to rule out the possibility of a secondary bacterial infection.

Always wash well with warm water and anti-bacterial soap after handling a bird that is parasitized by mites or lice, and launder your clothes in hot water. Consult your doctor and a professional exterminator if you observe these invertebrates on your person or in your home.
