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。

Christmas-flower

The Christmas flower (Euphorbia pulcherrima), universally known as the poinsettia, is a shrub or small tree in the family Euphorbiaceae, native to Mexico and Central America. In its native habitat it can reach heights of several meters, growing in seasonally dry tropical forests and woodland margins. The species is globally recognized as the quintessential Christmas ornamental plant, grown commercially on a massive scale for the holiday season in the Northern Hemisphere. What appear to be colorful flowers are in fact specialized leaf bracts — modified leaves in red, pink, white, or multicolored forms — that surround the small, true flowers called cyathia. Flowering is triggered by short days and long nights, a photoperiodic response that in nature aligns with the shortening days of autumn and winter. The milky white latex sap of poinsettias is mildly irritating to skin and mucous membranes, though contrary to popular belief the plant is not highly toxic to humans or most animals. In Mexico, the poinsettia has been cultivated for centuries and holds cultural and medicinal significance in traditional practices. Wild populations in Mexico face some pressure from habitat loss, though the species is not considered globally threatened.
