體型 Size
成鳥的頭部和身體長約 6 英吋(15 公分).尾巴長 9 英吋 (23 公分),長度可達身體的 1.5 倍!
The length of an adult's head and body is around 6 inches (15 cm). Their tail, which is nine inches (23 cm) long, can reach a length of 1.5 times that of their body!
形態描述 Morphology
牠們有強壯的後肢、敏銳的聽力和長尾以保持平衡,還有一雙大眼睛,讓牠們有良好的夜視能力.由於有蝙蝠般的聽覺,牠們可以在黑暗中追蹤昆蟲.牠們可以從空中抓住昆蟲或在地上捕捉昆蟲.牠們是敏捷的動物.當牠們在茂密的樹葉中穿梭時,會將脆弱的耳朵向後收以保護自己.休息時,牠們也會把耳朵折起來.除了後腳的第二個腳趾有一個梳理用的爪子外,牠們的大部分腳趾都沒有趾甲.
Together with their strong hind limbs, keen hearing, and long tails for balance, they also have huge eyes that allow them good night vision. They can track insects in the dark because of their bat-like hearing. They can seize insects out of the air or catch them on the ground. They are swift and nimble animals. They tuck their fragile ears back to shield themselves as they bound through the dense foliage. When at rest, they fold them as well. With the exception of the second toe on the hind foot, which has a grooming claw, the majority of their digits are nailless.
生態與棲息地 Habitat & Ecology
他們喜歡稀草林木地帶,也可以在各種環境中找到,包括林地、稀樹草原、山地森林和河流棲息地.
They prefer trees with little grass surrounding them and can be found in a range of environments, including woodlands, savannas, montane forests, and riverine habitats.
食性 Diet
一般而言,牠們吃三種不同數量和組合的食物:樹膠、水果和小生物(主要是昆蟲).
In general, they eat three different kinds of food in different amounts and combinations: gums, fruits, and small creatures (mostly insects).
繁殖 Reproduction
嬰兒出生時半閉著眼睛,經過 110-133 天的妊娠期後,最初無法自行走動.幾天 (6-8 天) 之後,母熊會用嘴叼著小孩,放在樹枝上餵食.雌性會變得相當好鬥,會生下單胎、雙胎或三胎.每個嬰兒的體重都在 5 盎司 (14 克) 以下.在最初的三天,嬰兒和母親有持續的接觸.在母親餵哺六週後,兩個月大的幼鳥就可以開始自己覓食.幼鳥的發育速度很快,常常讓母親抱著牠們走路時很滑稽.成熟後,雄性會離開母親的領地,但雌性會保留與幼仔共享的領地.因此社會群體是由緊密聯繫的雌性和牠們的後代所組成.一隻成年雄性通常會與特定區域內的所有雌性交配.成年雄性會維持與雌性社群重疊的獨特領域.尚未建立領地的雄性偶爾會組成小型的單身族群.
Infants are born with half-closed eyes and are initially unable to move around on their own after a gestation period of 110–133 days. After a few (6–8) days, the mother feeds the child by holding it in her mouth and placing it on branches. Females can become quite aggressive and have singles, twins, or triplets. Every infant is under five ounces in weight (14 g). The baby and mother have continuous touch during the first three days. After the mother feeds them for six weeks, the young can start feeding themselves at two months old. The babies develop quickly, which frequently makes the mother walk funny when carrying them. Once they reach maturity, males leave their mothers' territories, but females keep a territory they share with their young. Social groups are thus made up of females who are closely linked and their offspring. One adult male typically mates with all the females in a given area. Adult males maintain distinct territories that overlap with the social groupings of females. Small bachelor groups are occasionally formed by men who have not yet established such territory.
