Giant Hummingbird (Patagona gigas peruviana) 14 December 2017. Valle de Santa Eulalia, Lima, Peru.
This is the world's largest hummingbird reaching a length of up to 9". It flies with extremely slow wing-beats for a hummingbird. It is the only species in its genus and it has no close relatives. Some recent authors (HM4) have placed it in its own subfamily: Patagoninae. I believe this is an immature showing white edges to its flight feathers which adults lack. Bird was defending a territory of bright red flowers (bottom). Canon PowerShot SX50 HS.
