The monotypic Eulacestomatidae family, consisting of a single species, the Wattled Ploughbill, is endemic to the montane forests of New Guinea.

Overview of Eulacestomatidae

The Wattled Ploughbill (Eulacestoma nigropectus), whose name means “ploughshare-bill,” is an enigmatic songbird from the highlands of New Guinea. The male, with two large pink wattles below its uniquely shaped bill, is unmistakable. These active foragers often join mixed-species flocks, searching all sides of branches and branchlets for insects. Their song is a long, high, ringing whistle. Surprisingly, very little is known about the breeding biology of the Wattled Ploughbill, making it one of the most mysterious birds.
