Taxonomy and species list

The genus Chalcostigma was introduced in 1854 by the German naturalist Ludwig Reichenbach.[1] The type species was subsequently designated as the bronze-tailed thornbill by George Gray.[2][3] The name of the genus is derived from the Greek khalkos meaning bronze and stigme for a spot or mark, a reference to the beard on the bronze-tailed thornbill.[4]

The genus contains the following five species:[5]

• Rufous-capped thornbill (Chalcostigma ruficeps)
• Olivaceous thornbill (Chalcostigma olivaceum)
• Blue-mantled thornbill (Chalcostigma stanleyi)
• Bronze-tailed thornbill (Chalcostigma heteropogon)
• Rainbow-bearded thornbill (Chalcostigma herrani)
