Guaruba guarouba


金黃鸚鵡学名Guaruba guarouba),舊稱金黃錐尾鸚鵡金色錐尾鸚鵡,又名黃金鸚鵡金色長尾鸚鵡,俗稱大金黃,是一種鸚鵡。牠們的身體大部份呈黃色,故得此名。牠們棲息在巴西亞馬遜盆地較乾旱的高地雨林內。牠們受到伐林及水浸的威脅,非法捕獵也令牠們野外的數量下降。[2]

野生的金黃鸚鵡愛好玩耍及社交,甚至會照顧無關的雛鳥。不過,飼養下的金黃錐尾鸚鵡卻很少會有這種行為,有時會將雛鳥丟下3個星期。[2]牠們吃果實花朵、芽、種子玉米。食物當中包括芒果巴西莓[3]

金黃鸚鵡1歲就達至性成熟,繁殖季節是介乎11月至翌年的2月。牠們在樹洞裡面咬巢,並會保護鳥蛋。蛋長37.1毫米及闊29.9毫米,孵化期為30日,雄鳥及雌鳥會輪流孵蛋。性成熟後的頭幾年,雌鳥會生一些未成熟的蛋,直至6-8歲。飼養的金黃鸚鵡雛鳥若被帶走,雙親會再次進行繁殖。[2][4]

初生的金黃鸚鵡有一層白色絨毛覆蓋,這層絨毛一星期後就會變深色。到了第三星期,飛羽開始生長。雛鳥很愛玩耍,但也會欺負同輩。[2]

保育狀況

[编辑]

金黃錐尾鸚鵡被世界自然保護聯盟列為瀕危[1]這是因伐林及被捕獵所致。當地認為牠們是害鳥,因牠們會吃農作物,故被獵殺。[2]牠們是《瀕危野生動植物種國際貿易公約》附錄一所保護的物種[5]
