Buckelwal

大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。

ムジシギダチョウ

The cinereous tinamou (Crypturellus cinereus) is a ground-dwelling bird in the family Tinamidae, found across lowland Amazonia in South America, including Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and the Guianas. It inhabits humid tropical forest interior, particularly terra firme and occasionally várzea, where it walks through the undergrowth foraging for fallen fruits, seeds, and invertebrates. Like all tinamous, it has a round body, reduced wings, and strong legs adapted for a largely terrestrial lifestyle, and it produces a distinctive haunting whistle heard throughout Amazonian forest. The cinereous tinamou is classified as Least Concern by the IUCN, with a wide Amazonian distribution and populations that, while sensitive to hunting pressure, remain abundant in intact forest. Tinamous are among the most ancient lineages of birds, more closely related to rheas and ostriches than to most modern birds. This species is hunted for food by forest communities across its range. Its distribution is entirely within Amazonian South America, and it has no presence in Europe; any Norwegian database record is a data entry error. Conservation of Amazonian forest is the primary need for this species, as it is vulnerable to hunting pressure and habitat loss from deforestation. Males incubate the eggs and raise the chicks, a pattern unusual among birds.
