茶色蟆口鸱
英文名:Tawny Frogmouth
学名:Podargus strigoides
身长:33-50cm
分布最广泛、最常见的蟆口鸱,分布遍及澳洲各地。不过因为是夜行性,而且颜色通常和环境混为一体,所以并不容易见到。
Tawny frogmouths are birds that are awake at night.
They are not owls.
They eat insects, frogs and small animals.
Their covering is feathers.
To hide, they sit very still and look like a tree branch.
The Tawny Frogmouth is often thought to be an owl, but is in fact related to nightjars. There are 14 species, or kinds, or frogmouth.
Habitat and Distribution (where they are found)
Frogmouths are commonly seen throughout Australia, but not in rainforests or deserts. Tawny frogmouths prefer open eucalyptus woodland.
Appearance and Behaviours
Frogmouths do not have strong talons (claws) like owls.
Males and females look alike, and are 35-50 cm long.They have yellow eyes and a wide beak topped with a tuft of bristly feathers. They make loud clacking sounds with their beaks and their call sounds like drumbeats.
Owls fly around at night hunting food, but Tawny Frogmouths generally remain sitting very still on a low perch, and wait for food to come to them. They catch prey with their beaks, and sometimes drop from their perch onto the prey on the ground.
Tawny frogmouths hunt at night and spend the day roosting on a dead log or tree branch close to the tree trunk.
Their camouflage is excellent - staying very still and upright, they look just like part of the branch.
Diet
The Tawny frogmouth feeds on rats, mice, cicadas, beetles, frogs and other small prey. They catch their prey with their beaks rather than with their talons, another way in which they are different from owls.
Life Cycle
Tawny frogmouth pairs stay together until one of the pair dies. They breed from August to December. They usually use the same nest each year, and must make repairs to their loose, untidy platforms of sticks. After mating with the male, the female lays two or three eggs onto a lining of green leaves in the nest. Both male and female take turns sitting on the eggs to incubate them until they hatch about 30 days later. Both parents help feed the chicks.The chicks move to the edge of the nest and direct their droppings over the edge. About 25 days after hatching, the chicks are ready to leave the nest and lead their own lives.




茶色蟆口鴟,又名褐蟆口鴟、茶色蛙口鷹、茶色夜鶯或茶色夜鷹,是一種蟆口鴟,主要分佈在澳洲、塔斯曼尼亞及新畿內亞南部。茶色蟆口鴟一般都被認為是貓頭鷹。
雄鳥與雌鳥相似,約長35-150厘米。牠們的眼睛是黃色的,闊喙上有一束羽毛。牠們可以用喙發出響聲。
茶色蟆口鴟偽裝成樹幹。
茶色蟆口鴟於夜間飛行獵食,早上會留在樹上,等待獵物的到來。牠們會用喙捕捉獵物而不用鈎爪,有時從樹上衝往地上捕捉獵物。牠們的偽裝很好,當不動時,會以為牠們是樹幹的一部份。茶色蟆口鴟吃老鼠、蟬、甲蟲、青蛙及其他細小的獵物。
茶色蟆口鴟成雙成對的生活,直至另一方死去。牠們於每年的8月至12月交配。牠們會住在同一個巢中,並會修理鬆散及不整齊的部份。雌鳥與雄鳥交配後,會在巢中產下2-3顆蛋。雄鳥及雌鳥會輪流看守蛋,約於30日就會孵化。牠們會一同的哺育雛鳥。雛鳥孵化後25日就可以離巢過自己的生活。
