Just like humans, cockatiels can also suffer from allergies. Some signs of allergies in cockatiels are wheezy breathing, sneezing a lot, and watery eyes. It's very important that you do not mistake allergies with your bird having a cold.
If you suspect your cockatiel might have allergies, you might want to develop a checklist to rule out what your cockatiel might be allergic to. Things like a perfume you wear, or a cockatiel food treat can provoke allergies on your cockatiels. What kind of material is the cage cover made of? Certain materials might not be welcome by your cockatiel.
Also, when you wash the cage or the cage cover, you might be using a strong detergent that might make your tiel have an allergic reaction.
Do take a close look at your cockatiel diet. Put your cockatiel on an allergen-free diet (no wheat, no peanuts, no dairy, no chemicals -tap water, preservatives- etc) go over every single thing your cockatiel eats and look at the ingredients (most treats have peanuts or peanut butter or wheat products in them) and put your tiel on a health diet (everything organic, distilled water, no preservatives, etc).
Cockatiels can produce large amounts of dust. This fine white dust can cover pretty much everything near your cockatiel's cage, especially objects that draw dust with static, like the television. This dust comes from white powder-down feathers that grow close to the bird's skin. This powder helps keep your bird's feathers soft and silky. If you are susceptible to fine dust that might trigger allergies then you might want to rethink if a cockatiel is right for you. This dust can also create respiratory issues for people suffering from asthma.
To alleviate cockatiel dust in your house you can try to implement the following tips:
• Bathe your cockatiel once a week. Use a clean atomizer reserved only for this purpose and fill it with clean, warm water. Spray a light mist up in the air so that it gently falls down upon your cockatiel.
• Use an air filter in the same room where your cockatiel's cage is located. Continuous HEPA Filtration Takes the particles out of the air, and it is important for the health of both birds and their owners. Since this is a particulate problem, the best type of filtration is high efficiency particle arresting (often shortened to HEPA) filtration.
• Clean Regularly. A regular cleaning schedule will greatly help reduce the amount of irritants that can be inhaled.
