Description (10)
Image of Streaked Antwren
 

Family
Thamnophilidae (Typical Antbirds)

Size
9.50 cm

First Described (Guide)

Range (Guide)
Brazil, French Guiana, Guyana, Suriname, Venezuela.

Southern Venezuela (southern Delta Amacuro, Bolí­var, Amazonas), the Guianas and northern Brazil (eastern Roraima east to Amapá).
 
Population
Estimated population is unknown (2013) and stable.

Status VU
Habitat destruction and degradation through accelerating deforestation as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network, is the main threat.

For more information see BirdLife International Species Factsheet.

Habits
Forages in tangles and other dense foliage overhanging water, usually solitarily or in pairs, but occasionally in mixed-species flocks.

Subspecies
Myrmotherula surinamensis (Sibley and Monroe 1990, 1993) has been split into Streaked Antwren (Myrmotherula surinamensis), Pacific Antwren (Myrmotherula pacifica) and Amazonian Streaked Antwren (Myrmotherula multostriata) following SACC (2005).

Considered a sister-species of Amazonian Streaked Antwren (Myrmotherula multostriata) and until recently was treated as conspecific with that and also with Pacific Antwren (Myrmotherula pacifica), but vocal and plumage characters indicate that they are all separate species. Genetic and morphological analyses indicate that all three species are part of a monophyletic group that also includes Pygmy Antwren (Myrmotherula brachyura), Moustached Antwren (Myrmotherula ignota), Cherrie's Antwren (Myrmotherula cherriei), Klages's Antwren (Myrmotherula klagesi), Stripe-chested Antwren (Myrmotherula longicauda), Sclater's Antwren (Myrmotherula sclateri) and Yellow-throated Antwren (Myrmotherula ambigua) (the "streaked antwren assemblage").

No subspecies.

Similar Species
Male Cherrie's Antwren (Myrmotherula cherriei) is more heavily streaked black, and hence looks blacker. Female Cherrie's Antwren (Myrmotherula cherriei) has a much paler orange colouration than that of Streaked Antwren (Myrmotherula surinamensis).
