10 Everyday Items That Are Toxic to Birds

Birds can be like toddlers: They are both very oral and like to check things out by putting them in their mouths. Just like children, when pet birds are out unsupervised, this habit of tasting things can get them into trouble. As an avian veterinarian, I treat birds every week for getting into toxic substances. Though some foods and objects are clearly potentially toxic to birds, there are others that might not be so obvious. Also, what may be toxic to one bird species may not be to another. Despite some variability in species susceptibility to certain toxins, as well as a lack of scientific studies proving the toxicity of certain substances in birds that are definitely toxic to mammals, there are some items to which birds should never have access. Here are perhaps the top 10 toxins for which I treat bird patients in my veterinary practice.

1. Heavy Metals, Especially Lead, Zinc and Copper

Metals are everywhere in our environments and are an often overlooked source of toxicity in pet birds. Metals can be found in paint, linoleum, soldering, wire, zippers, twist ties and many other objects on which birds love to chew. Even some older bird toys, especially the clappers on metal bells, have been found to contain lead. Birds who may chip away over time at a lead-painted windowsill, lick a metal bell toy, nibble on the soldering of a stained glass Tiffany lamp or chew on a metal zipper are constantly ingesting heavy metals and can potentially become intoxicated. When ingested in large enough quantities, these metals can damage nerves and cause vomiting, maldigestion, neurologic signs, such as imbalance and clenched toes and even seizures. Most cases of heavy metal toxicity in birds are treatable if they are diagnosed early enough before permanent nerve damage has occurred. However, these metals are not routinely tested for in birds unless the owner indicates that his or her bird has been exposed. So, if you think your bird may have ingested any of these substances, speak up to your veterinarian immediately, as it could be the difference between life and death.

2. Avocado

Several parts of the avocado plant, but especially the leaves, contain a fatty acid derivative called persin, which has been reported to cause heart failure, respiratory distress and sudden death in a variety of bird species. It is possible that some varieties of avocado are safe for some bird species, such as Lories, who have been fed avocado without problems. However, no one is sure what types of avocado are okay for which species, so it’s better to be safe and not offer your bird the guacamole.

3. Caffeine

Caffeine may be a pick-me-up for you but a definite downer for your bird. Caffeinated drinks such as coffee, tea and soda are tempting to share with your bird, but even a few sips of these beverages can be extremely hazardous to your feathered pal. Caffeine may cause increased heart rate, arrhythmias, hyperactivity and even cardiac arrest in birds. So stick to water and occasional sips of safe fruit drinks, such as apple or cranberry juice, and keep him heart healthy.

4. Chocolate

Like us, many birds love chocolate. But chocolate can cause vomiting and diarrhea in birds. Even worse, chocolate contains both caffeine and theobromine, which can increase heart rate, cause hyperactivity, induce tremors and seizures, and potentially lead to death in birds. In general, the darker the chocolate, the higher the percentage of cacao (which are the seeds that contain theobromine and caffeine) and the more toxic it is to your pet. Do your birds a favor — give them a sugary fruit treat, like a slice of ripe banana or some juicy grapes, and save the chocolate for yourself.

5. Onions and Garlic

These yummy spices, believed to be heart healthy for people, are well-known toxins to dogs and cats and have caused fatalities in geese and other pet birds. Onions — cooked, raw or dehydrated — contain sulfur compounds that, when chewed, can cause rupture of red blood cells, leading to anemia (inadequate numbers of red blood cells). Onions also can irritate a bird’s mouth, esophagus and crop, and may lead to ulcers. Garlic contains a chemical called allicin, which in rare cases also can cause anemia in birds. Bland is best in birds — keep the spices out of your birdie’s body.

6. Salt and Fat

Salt: Many of us overindulge in this favorite condiment, and birds love it, too. Let’s face it — what bird doesn’t love to munch on a bunch of salty chips, popcorn, crackers or pretzels? But for a small bird, a few chips or pretzels can contain potentially toxic amounts of salt that can upset his electrolyte balance, leading to excessive thirst, dehydration, kidney dysfunction and even death. Similarly, fatty foods, such as large amounts of butter, nuts and fatty meat, can lead to the buildup of fat deposits within arteries (known as atherosclerosis) that can make some birds, like people, prone to heart disease and stroke. Some bird species, such as Amazon parrots and Quakers, seem to be predisposed to high cholesterol and triglyceride levels and to coronary artery disease, just like humans. Also, in general, the smaller the bird, the higher the risk with even a few bites of high fat or high salt foods, so to be safe, simply avoid these foods in birds’ diets.

7. Fruit Pits and Apple Seeds

Most birds love fruit, and most fruit is safe for birds. But when offered certain fruits with seeds (like apples and pears) and pits (like cherries, apricots, peaches, nectarines and plums), birds should never be allowed to eat the seeds and pits, as they contain small amounts of cardio-toxic cyanide. The seeds found in other fruits, such as grapes, citrus fruits, squash, pumpkins, tomatoes, melons, mangoes, pomegranates and berries, all are safe for bird consumption. Just core out the seeds and pits of cyanide-containing fruits and let your birds enjoy the rest.

8. Xylitol

Though this artificial sweetener, found in sugarless gum and many diet foods, hasn’t been studied extensively in birds, it causes severe hypoglycemia, liver damage and potential death in dogs. Consequently, it’s best not to take chances in birds who have a higher metabolism than most mammals and who could potentially be affected by very small amounts of this chemical. Birds don’t need to chew gum or eat artificially flavored low-cal foods. Overweight birds can munch on low-starch veggies to keep calories down. Keep the sugar-free stuff away.

9. Smoke and Other Aerosols

Along with the edibles, there are some other things that can be highly toxic to birds. For example, smoking is unhealthy enough for people, but it’s even worse for birds, whose airways actually inhale and exhale simultaneously with every breath and who are extremely sensitive to smoke and other aerosols. Spray cleaners, hair spray, perfumes, incense and even candle fumes can irritate birds’ lungs and air sacs (little clear membranes birds have throughout their bodies under their skin to help them breathe). These products should never be used around birds, and if birds are accidentally exposed to them, they should be moved to well-ventilated areas immediately. Exposed birds who do not start to breathe at a normal rate and with normal effort simply with better ventilation should be brought to a veterinarian as soon as possible for supportive therapy, such as fluids and oxygen. The moral is: If you’re going to spray, keep the birds away.

10. Teflon

Most bird owners know, but a few still do not, the dangers of nonstick cookware around birds. When Teflon and other nonstick surfaces are heated to very high temperatures, they emit microscopic vapors that when inhaled by birds’ exquisitely sensitive respiratory tracts can cause instant death. Numerous birds within a single household have been reported to die simultaneously when Teflon pans are burned near them. In general, all nonstick cookware and other nonstick coated appliances, including some stoves (in particular, the self-cleaning oven feature) and toasters, should be avoided in homes with birds. If birds are exposed accidentally to fumes from these pans or appliances, they should be brought to a well-ventilated area, such as the outdoors, immediately to help clear their airways. Unfortunately, even with immediate relocation to a better ventilated area, most birds exposed to these fumes die quickly without any signs before they can be brought to an animal hospital for oxygen therapy and other treatment. The manufacturer of any questionable appliance should be contacted before these appliances are used around birds. In general though, the rule is for bird owners is: Just say no to nonstick.

Of course, there are many other toxic items potentially toxic to birds, such as certain plants, lurking in our homes. If we just use common sense, supervise our beloved birds when they’re out of their cages, and offer them only nontoxic foods and toys to chew on, they are more likely to remain safe and happy. As always, if you have any questions about whether something could be potentially toxic to your pet, consult a bird-savvy veterinarian.

Most Common Obese Exotic Pets: No. 1 Parrots

Does Polly want a cracker? Maybe. But should Polly have a cracker? The answer is no. Polly, like many pet birds and other types of exotic pets, is prone to obesity. With little exercise and too much time to sit around and eat out of boredom, too many captive animals become overweight. With the extra pounds, these animals, like overweight people, can develop numerous health problems. The battle against the bulge has become the litany not only of physicians but also of veterinarians across the U.S., and it’s not a problem limited to pet dogs and cats. Species of all kinds can suffer from being fat, and as an exotic animal veterinarian, I constantly tell my patients’ owners to increase their pets’ exercise and limit their junk food consumption. As everyone tries to make good on their resolutions for a happier, healthier life in the New Year, let’s not forget our exotic friends. This week, we’ll look at the top five species I treat for obesity.

In my weeklong countdown, No. 1 for today are parrots!

The Feathered Shouldn’t be Fat

Many bird species, particularly Amazon parrots, African gray parrots, budgerigars and Quaker parrots, tend to gain weight, especially as they age. Their sedentary lifestyles; lack of purposeful activity; and consumption of high-fat, often all-seed diets lead them to overeat and gain weight. The problem is worse in birds as they reach their late teens and 20s and hard to correct unless their owners are willing to change their pets’ diets and encourage them to exercise. Like obese people, these obese birds are prone to developing significant, often life-threatening health problems, such as atherosclerosis (the deposition of cholesterol within major blood vessels exiting the heart that can obstruct blood flow, predisposing to heart attacks, and break off, blocking oxygen delivery to tissues and leading to strokes). In addition to circulatory issues, obese birds can develop joint problems, such as arthritis, from the stress of extra weight on the joints, and metabolic problems, such as fatty liver disease and diabetes.

To help combat obesity in their pets, bird owners must convert their pets to a predominantly pelleted diet, supplemented with some fresh produce and little to no seed, and increase their birds’ exercise level by allowing them to fly around the house or at least to walk around and flap if their wings are clipped. Weight loss in birds should be a slow and gradual process, and good eating and exercise habits must be maintained lifelong, or weight gain will recur, just as it does in people. It’s often hard to tell just by looking at birds if they have gained or lost weight as they can fluff up their feathers and look “big” even though they might be thin. Weighing birds on a scale that measures in one-gram increments is the best way to monitor weight gain or loss. For help with this and before starting any diet or exercise plan with your feathered friend, be sure to consult with your veterinarian first, so you know how to help your pet bird lose weight safely.

5 Things You Don’t Know About Cockatiels

Cockatiels are phenomenal birds and perhaps the most popular bird I see in my veterinary practice these days. Why are these little animals so beloved? Here are five facts about cockatiels that may surprise you.

1. Cockatiels make great first pets — feathered or otherwise.

Without a doubt, cockatiels, which are one of the smaller species of pet parrots, are the first bird I recommend for new pet owners or families, especially those with elementary school-age children or older. They are large enough to be sturdy in the hands of a child (although always under adult supervision, please!) but not so large that they are daunting. They are extremely social and love spending time with their human flock mates. They clearly recognize their caretakers and are responsive to their voices. They are fairly easy to care for, so they can be perfect first birds for people or families learning about the responsibilities of having a pet and/or the unique care needs of birds.

2. Cockatiels are extremely smart and can be taught to talk and do tricks.

Search YouTube, and you’ll find hundreds of videos showing cockatiels dancing, singing and hamming it up. People love to see birds do silly things, and cockatiels love to perform for rewards. Simply offer them a treat right after they complete a behavior, and the performance of the behavior will be reinforced. Reward this behavior repeatedly over time, and the bird will eventually perform it in anticipation of the treat.

3. Cockatiels are relatively long lived.

Many people think that only large parrots can live a long time, but when cared for properly with proper nutrition and preventive medical care, cockatiels can live to be 20 or older. The oldest reported cockatiel is nearly 30 years old. The longevity of these birds makes them attractive as pets for people who want a long-lived pet with whom they can bond like a family member.

4. Cockatiels come in a variety of feather patterns and colors.

When you hear “cockatiel,” most people picture the typical wild-type gray-and-white-feathered bird with a yellow head and pretty orange cheek patches. Though wild-type birds are certainly the most common type of cockatiel, these attractive birds can actually have many different feather colors and patterns. The variety is due to genetic mutations of the gray wild type. Cockatiels can have not only varied feather colors but also varied eye and skin colors. For example, some cockatiels have red eyes, while others have dark, or may have gray skin on their feet, while others have pink.

5. Cockatiels need preventive medical care, just like dogs, cats and people.

Most of us take our dogs and cats (and, I hope, ourselves) to the doctor for checkups regularly, so why not our birds? As they age, birds are subject to developing many of the same conditions we develop, such as kidney failure, atherosclerosis (hardening of the arteries with fat deposits) and arthritis. Many of these conditions can be prevented or at least treated when caught early with diagnostic testing, such as blood analysis and X-rays. Unfortunately, many cockatiel owners wait to take their pets to the vet until they are showing signs of illness, and at that point, disease may be so far advanced that it’s difficult to treat. To stay happy and healthy, cockatiels need to be fed proper nutrients, including calcium and protein, and should be screened annually for disease.

The bottom line is this: With advice from a bird-savvy veterinarian on how to provide appropriate daily at-home care and regular veterinary attention, these feisty little birds can make wonderful and long-lived companions!
