桂紅腹刺花鳥

The cinnamon-bellied flowerpiercer (Diglossa baritula) is a small, specialized bird in the family Thraupidae, found in montane cloud forests of Mexico and Central America, from the Sierra Madre del Sur in southern Mexico south through Guatemala, El Salvador, Honduras, and Nicaragua. It inhabits humid montane forest, cloud forest, and forest edge vegetation at elevations from approximately 1,000 to 3,000 meters. True to its name, the flowerpiercer uses its specially adapted, hooked bill to pierce the base of tubular flowers and extract nectar without pollinating the plant—a form of nectar theft. The male has gray-black plumage with a cinnamon-rufous belly, while females are brownish. The species is classified as Least Concern by the IUCN, with populations considered stable across its Mesoamerican mountain range. It is a resident of Central American and Mexican highland forests and is entirely absent from Europe; Norwegian database records are data entry errors. The flowerpiercers (Diglossa) represent a fascinating adaptive radiation in the Neotropics, with each species evolving slightly different bill morphologies for exploiting different flower types. Cloud forest habitats in Mesoamerica face ongoing deforestation pressure, but the species' broad elevation range provides some resilience.

白胁刺花鸟

白胁穿花鸟（Diglossa albilatera）是栖息于哥伦比亚至玻利维亚安第斯云雾林和林缘的中型穿花雀，具有深灰蓝色羽毛与独特白色胁斑的鲜明对比。与所有穿花雀一样，其尖锐钩状微上翘的喙可刺穿管状花基部盗取花蜜而不授粉，因此有「蜜贼」之名。见于海拔1,500至3,500米，在安第斯花园和林缘常能见到。
