白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

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.
