藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

灰頭鵐

The cinereous bunting (Emberiza cineracea) is a small passerine bird in the family Emberizidae, with a breeding range centered on Turkey, the Greek Aegean islands, and parts of the eastern Mediterranean and Middle East. It breeds primarily on arid, rocky hillsides and sparse scrub at low to moderate elevations, and winters in the Arabian Peninsula, northeastern Africa, and the Middle East. The male is a distinctive pale gray-yellow bird with a streaked brown back and yellow-tinged head, while females are more streaked and less colorful. The species favors dry, open habitats with sparse vegetation, often nesting on the ground or in low scrub. The cinereous bunting is classified as Not Evaluated by the IUCN in some assessments, though it has also been assessed as Least Concern in others, reflecting a small to moderate global population concentrated in the eastern Mediterranean and Turkey. It is entirely absent from Norway; any such database record is an artifact of data entry error. Like other buntings, it feeds primarily on seeds outside the breeding season and takes invertebrates during nesting. Habitat loss in its breeding range, particularly degradation of traditional dry-land farming and grazing landscapes in Turkey and Greece, represents the primary conservation concern.
