"If you like your house to smell nice, but don't want to use potentially toxic commercial air freshener sprays, here's a natural alternative that smells great & is totally bird safe. (Remember, scented candles, potpourri, incense & essential oils can all be potentially toxic to birds, as well).
Fill a small saucepan ½ full with water. Toss in a cinnamon stick, a Tb of cloves, tsp of rosemary, & slice of orange and/or lime (with peel).
Bring to a boil, then simmer uncovered for ½ hour or so. You can get creative by adding fresh grated ginger, fresh spearmint or peppermint leaves, or some nutmeg and allspice for variation. Your house will smell great & your birds will be safe! It's especially nice around the holidays. You can put it in a spray bottle & spritz the air, or leave the pan on the stove & add a little water, then re-simmer over the next few days to continue keeping your house sweet!"

"The use of commercial air fresheners is dangerous to parrots.
The only way to really freshen the air is to open windows and circulate fresh air with a fan or air conditioner.
Set out a dish of cut lemons or baking soda to absorb odors.
Simmer on the stovetop or in a slow cooker: water, slices of ginger, spices such as cinnamon, cloves, allspice, vanilla and almond extracts, and lemon and other citrus fruit slices to make your house smell fresh."
