TaxonomyEdit

The genus Margarornis was introduced in 1853 by the German naturalist Ludwig Reichenbach.[1] The name combines the Ancient Greek margaron meaning "pearl" with ornis meaning "bird".[2] The type species was designated by George Robert Gray in 1855 as Sittasomus perlatus Lesson. This taxon is now considered to be a subspecies of the pearled treerunner (Margarornis squamiger perlatus).[3][4]

SpeciesEdit

The genus contains four species:[5]

Image Scientific name Common Name Distribution
  Margarornis rubiginosus Ruddy treerunner Costa Rica and western Panama.
  Margarornis stellatus Star-chested treerunner Colombia and Ecuador.
Margarornis bellulus Beautiful treerunner Panama
  Margarornis squamiger Pearled treerunner Argentina, Bolivia, Colombia, Ecuador, Peru, and Venezuela

The white-throated treerunner is placed in the monotypic genus Pygarrhichas.[5]
