It might be helpful to potential owners to know how much to budget for their birds each year. A budget should include food, toys, insurance and vets bills, consumables such as full spectrum light bulbs, cleaning materials, etc. It should also have an allowance for capital items such as new cages (main and travel) and air purifiers which need replacement every ten years (ish) so add them up and divide by ten. Anything I have forgotten?
Obviously, need to know what type of birds as the bigger the bird, the bigger the budget I presume - this could be interesting.
