The Grey‑streaked flycatcher (Muscicapa griseisticta) is a small passerine bird in the family Muscicapidae, commonly referred to as an Old World flycatcher.
Taxonomy
- Family: Muscicapidae
- Genus: Muscicapa
- Species: M. griseisticta
- Authority: (R. Swinhoe, 1866)
Description
- Length: approximately 13 cm (5 in).
- Weight: 9–12 g.
- Plumage: Upperparts are olive‑brown with prominent grey streaks on the crown, mantle, and back. The underparts are pale whitish with faint streaking on the breast. The bill is short and black; the eyes are surrounded by a pale eye‑ring.
Distribution and Habitat
- Breeding range: Northeastern Asia, including the Russian Far East (Siberia), northeastern China, the Korean Peninsula, and parts of Mongolia.
- Wintering range: South‑east Asia, encompassing Myanmar, Thailand, Laos, Vietnam, Cambodia, peninsular Malaysia, Indonesia (Sumatra, Borneo), and the Philippines.
- Habitat: Breeds in mixed and coniferous forests, often near water bodies or in forest clearings. In winter it occupies forest edges, secondary growth, plantations, and lowland broad‑leaf forests.
Behavior and Ecology
- Migration: Long‑distance migrant; individuals move southward from breeding grounds in late summer and return north in spring.
- Diet: Primarily insectivorous, capturing flies, beetles, and other small arthropods by sallying from perches (fly‑catching behavior).
- Vocalization: Emits a soft, high‑pitched trill or series of thin “tsee” notes, used in territorial and courtship contexts.
- Breeding: Constructs a cup‑shaped nest on a horizontal branch or in a fork, typically using moss, leaves, and spider‑web silk. Clutch size is generally 3–5 eggs; incubation is performed mainly by the female.
Conservation Status
- The International Union for Conservation of Nature (IUCN) classifies the Grey‑streaked flycatcher as Least Concern. The species has a broad range and a relatively stable global population, though localized declines have been noted in areas experiencing extensive forest loss.
