Tasmanian Masked Owl
Tyto novaehollandiae castanops
Aboriginal name -Bok-Bok
Our Masked Owls, Owlbert and
Hootie, are unable to be released due to wing damage and amputation from road
and power line accidents. We hope they will breed in the future so we can
release the young to maintain good numbers of this beautiful Endangered creature
in the wild.
Female Tasmanian Masked Owls are the largest Barn Owls in the world. Masked Owls
display extreme Reversed Sexual Dimorphism, where the female is much larger than
the male. Females are 1.4 to 2 times the weight of the male.
They love to eat Quolls, Possums, Pademelons,
birds species and Antechinus. Masked Owls have a relatively large gape and
usually swallow prey in large pieces or whole. Their pellets often contain large
bones and whole skulls.
Caves and tree hollows and thick heavy foliage are favourite roosting places by
day. Masked Owls nest predominantly in large old. eucalypt tree's, preferably
with large hollows, in dry open forests.
The female lays 2 - 4 eggs in mid to late
October. They will hatch in 42 days, usually in very late November to early
December. Masked Owls are fledged in mid to late February.
Masked Owls have a deep. loud and harsh call similar to a Barn Owl and other
calls which are associated with breeding.
Sulphur-crested Cockatoo

FAMILY: Cacatuidae GENUS: Cacatua
SPECIES: galerita
The Sulphur-crested Cockatoo is a large
white parrot, measuring 45cm - 50cm. It has a dark grey-black bill, a
distinctive sulphur-yellow crest and a yellow wash on the underside of the
wings. Sexes are similar, although the female can be separated at close range
by its red-brown eye (darker brown in the male)
Sulphur-crested Cockatoos are common and
familiar in Australia. Their range extends throughout the northern and eastern
mainland, and Tasmania. Sulphur-crested Cockatoos are found in a variety of
timbered habitats and are common around human settlements. The birds stay in
the same area all year round.
The Sulphur-crested Cockatoo's normal diet
consists of berries, seeds, nuts and roots. Feeding normally takes place in
small to large groups, with one or more members of the group watching for
danger from a nearby perch.
When not feeding, birds will bite off
smaller branches and leaves from trees. These items are not eaten, however.
The activity may help to keep the bill trimmed and from growing too large.
Sulphur-crested Cockatoos breed in August to January in the south of their
range, and May to September in the north. The one to three eggs are laid in a
suitable tree hollow, which is prepared by both sexes. Both birds also
incubate and care for the chicks, which hatch after about 30 days. The chicks
leave the nest after a further 60 to 70 days, but remain with the parents all
year round. Family groups will stay together indefinitely
Pink (Major Mitchell) Cockatoo
FAMILY:
Cacatuidae GENUS: Cacatua SPECIES:
leadbeateri
Medium sized pink cockatoo with
distinct yellow and red bands in crest which is raised in alarm or display.
Very slight sexual dimorphism. Females have a (light) reddish-brown iris with
males a (dark) brown to black iris. Females also tend to have a wider yellow
band in the crest.
Length: 320-360mm.
Their distribution ranges
across the arid interior of mainland Australia. Status- Common Their favoured
habitat is Desert scrub, open woodland (mallee, Mulga and callitris) and
adjacent agricultural land.
Major Mitchell
Cockatoos eat a diet of mainly seeds,
grains, fruits, tubers and some insects. Theit time for breeding of this
species is July-January. Usual nesting site is a large hollow limb - often
bordering water courses - ranging in height from 3 to 20m. Both sexes
involved in nest preparation. Nest material may be chewed wood and bark. Both
sexes incubate the eggs and care for the young.
Like so many cockatoos, Male Major Mitchells
approach females with the body and crest erect. He bobs and flicks his head
from side to side excitedly and utters his normal call (also excitedly).
Females normally respond to this by ruffing her crest and bobbing the head.
Major Mitchells form strong pair bonds. Birds in a pair mostly enjoy each
other's company and sit close together. Mutual preening is practised all year
round.
Major Mitchells usually become sexually mature
at about 3-4 years of age, although younger birds (2yrs) have been known to
breed. Clutch: 1-3 white oval eggs. Incubation period: 26 days. Fledging
usually occurs at 56 days. .
