Peltopses include two unusual New Guinea endemic species of uncertain affinities. They are currently classified in the subfamily Peltopsinae within the Woodswallows and Butcherbirds (Artamidae). In the past they have been considered members of the Monarchidae or the Cracticidae (now merged with Artamidae), but may deserve full family rank. This thick billed species is also known as the Clicking Shieldbill for its dry clicking call notes. Their appearance and behavior remind me of the unrelated Swallow-winged Puffbird of South America.
