Gerygone sulphurea

Identification

9·5–10·4 cm

  • upperparts greyish-brown
  • moustachial stripe thin, white, often obscured
  • loral regon may be whitish
  • underparts yellow, generally paler on lower belly
  • vent area often off-white

  • bill black, generally robust
  • legs and feet black

Distribution

Southeast Asia: found in Indochina, Vietnam, Cambodia, Thailand, Malaysia, Borneo, Singapore, Philippines, Indonesia, Greater Sundas, Sumatra, Java, Bali, Sulawesi, Lesser Sundas

Taxonomy

Vocally the subspecies are quite different which may indicate the need to split into several species. Reference [3] suggests elevating subspecies sulphurea as "Sunda Gerygone", G. sulphurea, flaveola as "Sulawesi Gerygone", G. flaveola and subspecies rhizophorae and simplex as "Philippine Gergyone", G. simplex

Subspecies

Clements recognises the following subspecies [1]:

  • G. s. flaveola: "Sulawesi Gerygone". Sulawesi, Salayar and Banggai Islands (Peleng and Banggai) [underparts more saturated, tail tips indistinct]
  • G. s. sulphurea: "Sunda Gerygone". Malay Peninsula, Greater Sundas and Lesser Sundas
  • G. s. simplex: "Philippine Gergyone". Lubang, Luzon, Mindoro, Verde, Negros, Bohol and Cebu
  • G. s. rhizophorae: "Philippine Gergyone". Southern Philippines (Mindanao, Basilan and Sulu Archipelago)

Some authorities (e.g. [4], [5]) recognise subspecies muscicapa from Enggano Island (off Sumatra: described as smaller, underparts more saturated, neck and head paler).

Habitat

Open country, second growth, mangroves and residential areas.

Behaviour

Diet

Little known, but they eat insects gleaned from leaves higher up in the trees.

Movements

A resident species.
