CONSERVATION STATUS

Endangered

The Mariana Swiftlet is small swift that occurs on Guam, the northern Mariana Islands, and has been introduced to the Hawaiian island of Oahu. It forages for small arthropods while flying over forest, mangroves and grasslands. This species is thought to have a population of around 3,000 individuals and is in decline due to pesticide use and depredation by an introduced species, the Brown Tree Snake. It has been given a conservation rating of Endangered by the IUCN.

INTERESTING FACTS

  • Aerodramus swiftlets use a simple form of echolocation to navigate through the caves they roost and breed in. Unlike a bat, their clicking noises are easily heard by humans.
  • The Mariana Swiftlet was first described in 1909 by American ornithologist Edgar Alexander Mearns.
  • Their nest is composed of their gummy strands of saliva, which harden when exposed to air. The Chinese delicacy, bird's nest soup, is made from the harvested nests of swiftlets.
  • A group of swifts are collectively known as a "box", "flock", "screaming frenzy", and "swoop" of swifts.
