Many bird species exhibit sexual dimorphism, i.e., male and female
have differing appearances which can be quite subtle.
The easiest way to tell the sexes of Yellow-tailed Black-Cockatoos
apart is by the colour of the orbital skin around the eyes. In
males, left, it is pink, in females black.
Apart from that, females have larger and brighter yellow ear patches
and their bill tends to be a lighter shade of grey than the males'.

Breeding information |
| Breeding season: May - Jan | Eggs: 2 | Incubation period: 28 days | Fledging age: ca. 77 days |
The breeding season of Yellow-tailed Black-Cockatoos depends on geographic latitude. In the SE of Australia it is restricted to the period from Oct to May.
Usually only one of the two chicks survives. It is brooded by the female for about 3 weeks, before the male, who up to then fed the female, will also feed the chick itself.
| Nest building: Female(?) | Incubation: Female | Dependent care: First female, then female & male |

Yellow-tailed Black-Cockatoos are sociable birds that can often be
seen in small groups or flocks of up to 50 (sometimes hundreds
of) individuals

Food, Diet |
| Adults: Seeds | Dependents: Regurgitated seeds | Water intake: Daily |
Like basically all cockatoos, Yellow-tailed Black-Cockatoos are primarily seed-eaters, where seeds include those in cones and nut-like fruit. The pair shown above showed a strong interest in the cones of a casuarina tree on which they were found sitting; if that is the case, it indicates that their bills are strong enough to crack those cones.

Yellow-tailed Black-Cockatoos have been observed by us chomping on tree branches and young trees, apparently feeding on something under the bark, possibly in the (rotten?) core, see below.
Damage done by a Yellow-tailed Black-Cockatoo to a sapling tree;
Yellow-tailed Black-Cockatos are known to take grubs, such as
e.g. Witchety grubs, that may have caused the initial damage to
the plant's core
