澳洲野生白鸚鵡 Australian Wild White Cockatoo 在我住屋側拍攝
阿爾巴Cacatua(又稱雨傘鳳頭鸚鵡或U2),白鸚鵡,是中型,約46厘米(18英寸)長,印度尼西亞群島也有。白鸚鵡有棕色或黑色的眼睛和一個暗灰色的喙。驚訝時,它擴展了一個大的和引人注目的波峰,其中有一個半圓形的形狀類似雨傘,因此替代名稱。白鳳頭鸚鵡寵物可以培訓,翼和尾的底面有淡黃色或檸檬的顏色,當它們飛走時會閃爍
白鸚鵡可以活丘100年。
鸚鵡喜歡吃種子,塊莖,球莖,水果,花卉和昆蟲。他們經常大群一起取食物,鸚鵡是一夫一妻制,在樹洞築巢。一些鸚鵡種已受到不利還境影響喪失了棲息地,一些物種已經適應人的變化,被認為是農業害蟲。
鸚鵡是流行的養鳥,在野外捕捉鳥類及非法貿易 ,減少鸚鵡在野外的數量。
The White Cockatoo, Cacatua alba (also known as the Umbrella Cockatoo or U2), is a medium-sized, approximately 46 centimetres (18 in) long cockatoo endemic to the islands of Halmahera, Bacan, Ternate, Tidore, Kasiruta and Mandiole in North Maluku, Indonesia. This threatened white parrot has brown or black eyes and a dark grey beak. When surprised, it extends a large and striking crest, which has a semicircular shape (similar to an umbrella, hence the alternative name). Pet White Cockatoos may raise their crests upon training, or when something catches their interest such as a new toy or person. The undersides of the wings and tail have a pale yellow or lemon color which flashes when they fly.
The White Cockatoo can live up to, and perhaps beyond, 100 years.[citation needed]

Cockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly when ground-feeding. Cockatoos are monogamous and nest in tree hollows. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable nesting hollows after large mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests.
Cockatoos are popular birds in aviculture but their needs are difficult to cater for. The Cockatiel is the cockatoo species that is easiest to care for and is by far the most frequently kept in captivity. White cockatoos are more commonly found in captivity than black cockatoos. Illegal trade in wild-caught birds contributes to the decline of some cockatoo species in the wild.
