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.
