Taxonomy and systematics
editThe moustached woodcreeper has two subspecies, the nominate X. f. falcirostris (Spix, 1824) and X. f. franciscanus (Snethlage, 1927).[2] The latter has sometimes been treated as a separate species ("Snethlage's woodcreeper") and by at least one author as a subspecies of the white-throated woodcreeper (X. albicollis). Subspecies X. a. villanovae of the white-throated has sometimes been assigned to the moustached woodcreeper.[3][4]

Description
editThe moustached woodcreeper is one of the largest members of its subfamily. It is heavy-bodied, with a shortish tail and a long thin bill. It is 28 to 32 cm (11 to 13 in) long and weighs about 110 g (3.9 oz). The sexes have the same plumage. Adults of the nominate subspecies have a brown face with a buffy supercilium, lores, and moustachial stripe. Their crown is cinnamon-brown to dark olive-brown with thin buff streaks. Their back is rufous-brown and their rump, wings, and tail are cinnamon-rufous. Their throat is pale buffy to whitish and their underparts light brown to cinnamon-buff. Their flanks have faint buffy streaks and their central belly has faint grayish brown bars. Their iris is dark reddish to brown, their maxilla dark gray to black, their mandible pale gray to horn colored, and their legs and feet olive-gray to dark gray. Juveniles are similar to adults with wider and blackish streaks on the belly and a dark mandible. Subspecies X. f. franciscanus compared to the nominate has on average a shorter tail and a longer bill, darker and more olive underparts, weaker streaks on the crown, and narrower streaks on the belly. The subspecies overlap in all characteristics.[3]
Distribution and habitat
editThe nominate subspecies of the moustached woodcreeper is found in northeastern Brazil, from eastern Maranhão, Piauí, and northwestern Bahia east as far as western Paraíba and central Pernambuco. It occurs only locally within that area. Subspecies X. f. franciscanus is found in eastern Brazil west of the São Francisco River in western Bahia and northern and northwestern Minas Gerais. The species inhabits deciduous and semi-deciduous woodland, wooded caatinga, and gallery forest. It favors the interior of intact and slightly altered forest, tending to stay in the tallest growth. It occasionally occurs at the edges of the forest. In elevation it mostly occurs below 500 m (1,600 ft) but reaches as high as 800 m (2,600 ft) at sites in the northern part of its range.[3][5]
Behavior
editMovement
editThe moustached woodcreeper is a year-round resident throughout its range.[3]
Feeding
editThe moustached woodcreeper's diet is primarily insects, though it has been observed eating snails. It typically forages singly, in pairs, or in what are thought to be family groups; it shuns mixed-species feeding flocks. It is not known to follow army ant swarms. It mostly forages from the forest mid-level to the canopy but sometimes on the ground as well. It hitches along trunks and branches, probing cavities, bark, and especially bromeliads.[3]
Breeding
editThe moustached woodcreeper is thought to breed in the austral summer, roughly between October and December. No nest has been found, so the clutch size, incubation period, and time to fledging are not known. Both males and females have been found with brood patches, so both parents are thought to incubate eggs and care for nestlings.[3]
Vocalization
editThe moustached woodcreeper's song is a "series of 4-7 double-notes, like 'wèèè-TJUH wèèè-TJUH - -'." The notes often gradually change to "Tu-Tjuh". Its call is a "whining, drawn-out 'wèèè-tuh' " with the "tuh" being "high and dry".[5]
Status
editThe IUCN originally assessed the moustached woodcreeper as Threatened but since 1994 has classed it as Vulnerable. It has a fairly large overall range but is spottily found within it. Its estimated population of between 2500 and 10,000 mature individuals is believed to be decreasing. "The widespread destruction of dry forest in interior Brazil has rapidly reduced the now small population of this species. Remaining populations are severely fragmented and continuing to decline."[1] The species is considered uncommon to rare and very local. It is "[l]egally protected in Brazil, and conservation measures have had some success in setting aside key sites as parks and reserves."[3]
