Leaden flycatcher
The leaden flycatcher (''Myiagra rubecula'') is a species of passerine bird in the family Monarchidae. Around 15 cm (6 in) in length, the male is a shiny lead-grey with white underparts, while the female has grey upperparts and a rufous throat and breast. It is found in eastern and northern Australia, Indonesia, and Papua New Guinea. Its natural habitat is subtropical or tropical mangrove forests in the northern parts of its range, in the south and inland it is eucalypt woodland.
==Taxonomy==
The leaden flycatcher was first described by ornithologist John Latham in 1802, from an illustration in the Watling drawings.〔Boles (''The Robins and Flycatchers of Australia''), p. 322〕 Its specific name, ''rubecula'', comes from the Latin for robin. A local name around Sydney is ''Frogbird'', derived from its guttural call.〔Boles (''The Robins and Flycatchers of Australia''), p. 320〕 Other variants of its common name include blue- or leaden-coloured flycatcher.〔 John Gould described and named the Pretty Flycatcher (''Myiagra concinna'') in 1848, which has since been subsumed into this species.
The leaden flycatcher is a member of a group of birds termed monarch flycatchers. This group is considered either as a subfamily Monarchinae, together with the fantails as part of the drongo family Dicruridae, or as a family Monarchidae in its own right. They are not closely related to either their namesakes, the Old World flycatchers of the family Muscicapidae; early molecular research in the late 1980s and early 1990s revealed the monarchs belong to a large group of mainly Australasian birds known as the Corvida parvorder comprising many tropical and Australian passerines.〔Sibley, Charles Gald & Ahlquist, Jon Edward (1990): ''Phylogeny and classification of birds''. Yale University Press, New Haven, Conn.〕 More recently, the grouping has been refined somewhat as the monarchs have been classified in a 'Core corvine' group with the crows and ravens, shrikes, birds of paradise, fantails, drongos and mudnest builders.
