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。
ノドジロセッカ
The churring cisticola (Cisticola njombe) is a small insectivorous warbler in the family Cisticolidae, endemic to the highlands of East Africa. It inhabits montane grasslands, bracken-fern slopes, and the margins of high-altitude forest patches, primarily in the Nyika Plateau, the Njombe highlands of southern Tanzania, and adjacent areas of Malawi and Zambia. The species occupies elevations typically between 1,500 and 2,500 meters, where it forages low in dense grass and sedge clumps, gleaning insects and small invertebrates. The churring cisticola is named for its distinctive mechanical churring song, which males produce from low perches or during short display flights. It is a compact, streaked brown bird with a rufous-washed tail and pale underparts, closely resembling related montane cisticolas. The species is classified as Least Concern by the IUCN, with populations considered stable across its restricted highland range. Like other afromontane endemics, it depends on the persistence of intact highland grassland ecosystems, which face ongoing threats from agricultural encroachment, fire management changes, and human settlement. Taxonomic relationships within the Cisticola genus are complex, and the njombe cisticola has been subject to periodic revision. Conservation of afromontane grasslands in Tanzania and Malawi is critical for this and many co-occurring endemic species.
