The streak-headed woodcreeper (Lepidocolaptes souleyetii) is a

Furnariidae. It is found in Mexico, Central America, Brazil, Colombia, Ecuador, Guyana, Peru, Venezuela, and on Trinidad.[2]

Taxonomy and systematics

The streak-headed woodcreeper has these seven subspecies:[2]

Description

The streak-headed woodcreeper is 19 to 21 cm (7.5 to 8.3 in) long and weighs 23 to 31 g (0.81 to 1.1 oz). It is a slim, medium-sized woodcreeper with a longish, slender, decurved bill. The sexes have the same plumage. Adults of the

ochraceous to pale cinnamon-buff. Their iris is pale brown or brown, their bill pale brown or horn with most of the mandible bluish-pink, and their legs and feet grayish olive-green. Juveniles are very similar to adults but with small scattered dusky spots instead of streaks on their underparts.[4][5]

The other subspecies of the streak-headed woodcreeper differ from the nominate and each other thus:[4][6][7][8]

  • L. s. lineaticeps, crown and underparts streaks narrower than nominate's; rufous of rump, wings, and tail darker, dark brownish maxilla
  • L. s. littoralis, like lineaticeps but smaller, paler, less rufescent above and more buffy below
  • L. s. uaireni, like lineaticeps but darker overall, more whitish (less buffy) streaks, blacker edges on underparts streaks
  • L. s. compressus, like lineaticeps but darker with wider streaks above and below, pale buff to whitish throat
  • L. s. guerrerensis, slightly larger, paler red above, grayer below than compressus
  • L. s. esmeraldae, deeper buff throat and underparts streaks than nominate, shorter bill

Distribution and habitat

The subspecies of the streak-headed woodcreeper are found thus:[2][4]

The streak-headed woodcreeper inhabits a variety of wooded landscapes, most of them semi-open to open. These include deciduous and somewhat humid forest, gallery forest, secondary forest, plantations, the edges of humid forest, and open areas with scattered trees. It also locally occurs in mangrove and in arid scrublands. In elevation it reaches 1,500 m (4,900 ft) in Mexico, 1,850 m (6,100 ft) in northern Central America, 1,500 m (4,900 ft) in Costa Rica (though uncommon above 900 m (3,000 ft)), 1,500 m (4,900 ft) in Colombia, and 1,600 m (5,200 ft) in Venezuela. In Ecuador it mostly occurs below 800 m (2,600 ft) but reaches 1,800 m (5,900 ft) locally in Loja Province.[4][5][6][7][8][9]

Behavior

Movement

The streak-headed woodcreeper is a year-round resident throughout its range.[4][10]

Feeding

The streak-headed woodcreeper's diet is mostly non-flying

mixed-species feeding flocks. It captures prey by flaking bark and probing into crevices and moss clumps.[4][5][6][7]

Breeding

The streak-headed woodcreeper forms pairs during the breeding season but is generally solitary outside it. Its breeding season varies across its range, for example in June and July in Mexico and April to October in Colombia. It usually nests in tree cavities, either natural or excavated by a woodpecker, and pads the bottom with wood chips and bark pieces. It occasionally use nest boxes. Nests in trees are typically 3 to 25 m (10 to 80 ft) above the ground. The clutch size is two eggs. The incubation period is about 15 days; the time to fledging is not known. Both parents incubate the clutch and provision nestlings.[4]

Songs and calls

Vocalization

The streak-headed woodcreeper's song has been described as "a simple, descending, clear trill, soft and melodious", "a clear musical descending trill that lasts 1.5-3 seconds", "a high-pitched, thin, flat trill, p'e'e'e'e'e'e'e'eeeaaa, rapid and descending throughout, ca 2-2.5 sec." , and as "a loud, ringing, rapid, descending series of puttering notes: pee'i'i'i'i'i'i'i'i'i'i'i'i'i'i'i'i'ew".[4][5] Its calls include "a harsher, more rattling, shorter trill", "a soft plaintive pyuu", and "a loud, rapidly quavering, descending pee'i'i'u".[4]

Status

The

IUCN has assessed the streak-headed woodcreeper as being of Least Concern. It has a large range and an estimated population of at least 500,000 mature individuals, though the latter is believed to be decreasing. No immediate threats have been identified.[1] It is considered common through most of its range though less so at higher elevations. It "tolerates secondary forest, forest edge and open habitats. As these habitats are often a result of human-altered environments, this species is less sensitive to human activity than other woodcreepers."[4]
