Symposiachrus verticalis
The Bismarck Monarch (Symposiachrus verticalis) is a striking, medium-sized passerine, measuring approximately 15-16 cm (6 inches) in length, endemic to the Bismarck Archipelago.

It employs a classic monarch foraging strategy, sallying from a prominent perch to snatch flying insects (flycatching) or gleaning invertebr...
