The budgerigars diet consists of grass seeds, fresh green foods and some fruit now and again. You can find good grass seeds for your budgie in most pet shops, they will sell packs of mixed seeds that contain all the nutrients, vitamins and minerals your budgie needs for its diet. Buy the packs that are specifically named "budgerigar seeds" not just "bird seeds". Always buy fresh seeds, so don't buy enough food to store for a year, as it will only dilute in nutritional value. Buy enough food for around 2 months and store it in a dry place that gets plenty of air as to ensure it does not go mouldy. Try to buy a container to store the food with air holes or put it in a cloth bag and store in a cool dry place.
When you first have your budgie they may not want to eat any green foods or fruits, as they may have never been given any of this food before as it has lived in captivity. You can continue to put the green foods out even if they do not eat it at first, as they will more than likely build up the courage to eat it sooner or later. Try a variety of fruits, as they will soon learn to have favourites and remember to remove the food after a couple of hours before it goes off and mouldy. Do not over feed the fruit, one piece every other day is sufficient.
Budgerigars need more nourishment during the winter months when they start to moult and breed. At these times they will enjoy sunflower seeds, wheat germs, oats and other nutritional treats. You can even try giving them a slice of boiled egg or cottage cheese once a week.
Millet spray is a very nutritious food but is also fairly fattening, so try to limit them to a couple of inches of millet a day. Make sure your budgie is never left without seeds, keep an eye on the food container as what looks like a full tray could be disguised as a tray of empty husks, which look very much like the whole seeds.
Green plants and vegetables your budgie could enjoy are:
Fruits they may enjoy are:
Remember these foods can be very rich so always limit the amount you give to your bird, overfeeding them can cause stomach upsets and diarrhoea.
