Green-backed Hillstar Urochroa leucura

Large hummingbird with limited range on east slope of Andes from southern Colombia to Ecuador. Overall bronzy-greenish with blue throat. Very long, straight bill. Look for bold white flashes in tail, especially visible in flight. Could be confused with Lazuline or Napo Sabrewing, but note straighter bill and white tail. Uncommon; occasionally visits feeders but equally likely to be found within forest, especially around streams and waterfalls. Occurs from around 1,100 to 2,000 m.
