My sister's husband's cockatoos (Major Mitchells) in Balmain used to 
quietly wait and watch the House Sparrows come down and poke their heads 
through the cage wires to get at the cockatoo's spilt grain - a quick 
grab and a headless sparrow. The head was eaten. No cage is safe, inside 
or outside it seems.
