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.

[edit] Taxonomy

The Leaden Flycatcher was first described by ornithologist John Latham in 1802, from an illustration in the Watling drawings.[1] Its specific epithet is derived from the diminutive of ruber, Latin 'red'.[2] A local name around Sydney is Frogbird, derived from its guttural call.[3]Other variants of its common name include Blue- or Leaden-coloured Flycatcher.[4] John Gould described and named the Pretty Flycatcher (Myiagra concinna) in 1848, which has since been subsumed into this species.[5]

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,[6] or as a family Monarchidae in its own right.[7] 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.[8] 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.[9]

[edit] Subspecies

Five subspecies are currently recognised:

  • M. r. rubecula is the nominate subspecies originally described by Latham from Southeastern Australia.
  • M. r. concinna, called the Pretty Flycatcher by John Gould, occurs in northwestern Australia.
  • M. r. okyri was described by Schodde and Mason in 1999. It is an unusual non-migratory form from Cape York. The specific epithet is an anagram of yorki. The holotype was collected from Coen in north Queensland.[10]
  • M. r. papuana, from New Guinea and Torres Strait islands was named by Rothschild and Hartert in 1918.[11]
  • M. r. yorki was named by Gregory Mathews in 1912.[12]

The Leaden Flycatcher is 14.5-16 cm (6-6½ in) long and weighs around 10-15 g. It is a shiny lead-grey in colour with a brownish tinge to the wings, a bluish black bill, black legs and dark brown iris. The male has darker grey lores, and a white breast and belly, while the female has an orange-tan throat and breast with a white belly. The juvenile resembles the adult female, but with paler wing-edges.[4]

[edit] Distribution and habitat

The Leaden Flycatcher is found from King Sound in northwestern Australia, across the Top End to Cape York, and then down the east coast to central-southern Victoria. It is rare in Tasmania. It is highly migratory within this range. Sclerophyll forest, rainforest margins, mangroves and coastal scrub are the preferred habitats.[13]

[edit] Behaviour

As its name suggests, the Leaden Flycatcher is insectivorous. A very active and agile bird, it hops between branches and catches insects in flight.[4]

[edit] Breeding

Breeding season is September to February with one brood raised. The nest is a deep cup made of strips of bark and dry grass, woven together with spider webs and decorated with lichen, generally sited on a small branch well away from the trunk of a sizeable tree some 5-10 m above the ground. Two or three white eggs tinted bluish, greyish or lavender and splotched with dark grey-brown are laid measuring 17 mm x 14 mm. They have an unusual swollen oval shape.[13] The species is parasitised by the Brush Cuckoo (Cacomantis variolosus).[13]
