Field notes

  • Its extremely decurved bill was a specialized adaptation for extracting nectar from the deep, tubular flowers of endemic lobelioids.
  • The species was first described by science in 1893 and was last recorded only 14 years later in 1907, representing a remarkably rapid extinction following discovery.
  • Unlike its relative, the Hawaiʻi Mamo, this species lacked any yellow feathers and was almost entirely soot-black.
  • It was endemic strictly to the island of Molokaʻi, occupying the high-elevation forest canopy and understory.
  • The primary causes of its extinction are attributed to habitat destruction by feral livestock and the introduction of avian malaria via mosquitoes.
Habitat
Dense, humid montane rainforests and high-elevation bog margins.
Range
Molokaʻi, Hawaiian Islands (Extinct).
