My tiel Cheeko had a mate named Homer, who died from old age just about a year ago, he plucked out most of his feathers, it was quite sad. ..

we got him another cage mate soon after, Spanky *pic in sig* .. Some Tiels dont like to have another teil in their territory. so it is good to have another cage handy just in case. But cockateils are Flock birds so most of them prefure company of another bird, being a budgy or cockatiel ..
