It depends on whether you offer any other source of calcium. If you do, it's not necessary but, if you don't, it is (mind you, calcium alone doesn't work because they need vit D3 to absorb it).
All my birds have cuttlebones (I get them by the pound in three different sizes, small for the canaries and finches, medium for the cardinals and small parrots and large for the large ones). Now, my canaries, finches, cardinals and quails also get a 99% soluble mineral grit (a treat cup once every two weeks or so) that also has calcium as well as getting raw broccoli (a good natural source of it) once a week, and all my parrots get broccoli every day (in the gloop) as well as other sources of it (kale, oranges, almonds, sesame seeds- only during breeding and molting season, white beans, figs) and all the hens get a couple of doses of calciboost when they lay so it's not as if they actually need the cuttlebone for the calcium but they do love to chew on it -especially the amazons and the cockatoos, give them a new one and, in a matter of minutes, it's chewed into tiny little pieces. I've tried mineral blocks but they don't seem to like them much so I went back to the cuttlebone. My budgies always have cuttlebone and, although they are not maniacs about it like the zons, they do chew on it until there is nothing but the hard shell of it left.
