Bird cages will feature bars as a way of enclosing your pet. It's imperative that you pick the right spacing between the bars. If it's too narrow, then you'll have lesser visibility. On the other hand, if it's too wide, then your beloved pet can escape.
The size of your pet bird is the primary determining factor for finding the right bar spacing.
For small birds, the ideal bar spacing is one-half to five-eighths of an inch. Cockatiels, budgies, parrots, lovebirds, finches, parakeets, and canaries are often categorized as small birds.
Cockatoos, smaller amazons, smaller African greys, mini macaws, Senegal, Pionus, lories, and Quakers are typically considered as medium-sized birds. For such birds, a bar spacing of one-half to three-fourths of an inch is ideal.
Large birds include African Greys, toucans, Hyacinth macaws, and Congos. The bar spacing of three-fourths of an inch to one inch is ideal for these large-sized birds.
