The Monarch Flycatchers comprise a family of passerine birds which includes Boatbills, Paradise Flycatchers and Magpie Larks. They occur across sub-Saharan Africa, south-east Asia, Australia and a few Pacific Islands. Hybridization has been documented in one genus, Terpsiphone. Chapin (1948) discusses hybridization dynamics between Red-bellied Paradise Flycatcher (T. rufiventer), Rufous-vented Paradise Flycatcher (T. rufocinerea) and African Paradise Flycatcher (T. viridis) in Africa. In Northern Congo, hybridization between Red-bellied Paradise Flycatcher (T. rufiventer) and Bates’ Paradise Flycatcher (T. batesi) is common. About 35% of the territories are held by hybrids (Dowsett-Lemaire, 1999).
