Black-throated Mango

A large, striking hummingbird of tropical forests from southern Mexico to Argentina, black-throated mangos have dramatic sexual dimorphism — males display glittering black throat and breast with violet and green flanks and a bold purple tail, while females are white below with a central black stripe. Inhabiting forest edges, clearings, and gardens, they aggressively defend flowering trees. Males perform spectacular aerial display flights at treetop height. Listed as Least Concern across their broad neotropical range.
