The stripe-chested antwren (Myrmotherula longicauda) is a species of bird in subfamily Thamnophilinae of family
Taxonomy and systematics
The stripe-chested antwren has these four subspecies:[2]
- M. l. soderstromi Gyldenstolpe, 1930
- M. l. pseudoaustralis Gyldenstolpe, 1930
- M. l. longicauda Berlepsch & Stolzmann, 1894
- M. l. australis Chapman, 1923
Gyldenstolpe treated subspecies M. l. australis as a separate species but that treatment was not otherwise accepted.[3]
Description
The stripe-chested antwren is 9 to 11 cm (3.5 to 4.3 in) long and weighs 8 to 9.5 g (0.28 to 0.34 oz). It is a smallish bird with a somewhat longer tail than other members of its genus. Adult males have a black and white streaked face and neck. Their crown, back, and rump are black with white or pale gray streaks. Their tail is black with white edges and tips to the feathers. Their wings are black with wide white edges on the
Distribution and habitat
The stripe-chested antwren is found in a disjunct distribution along the eastern slope of the Andes. The subspecies are distributed thus:[4]
- M. l. soderstromi: southern Colombia's Putumayo Department south and northern Ecuador's Napo Province
- M. l. pseudoaustralis: from southern Ecuador's Morona-Santiago Province south into Peru as far as the Department of Pasco; also separately in Peru's Department of Loreto[8]
- M. l. longicauda: Peru's Department of Junín
- M. l. australis: from Cusco and Madre de Dios departments in southern Peru south into northwestern Bolivia as far as Cochabamba Department
In most of its range the stripe-chested antwren inhabits the edges of humid evergreen forest and also secondary forest and bamboo stands. In elevation it ranges between 400 and 1,550 m (1,300 and 5,100 ft) though only as high as 1,100 m (3,600 ft) in Colombia and mostly below 1,000 m (3,300 ft) in Ecuador.[4][5][6] The disjunct population in Loreto, Peru, inhabits permanently flooded forest around blackwater lakes at an elevation of about 150 m (500 ft).[4][8]
Behavior
Movement
The stripe-chested antwren is believed to be a year-round resident throughout its range.[1]
Feeding
The stripe-chested antwren's diet has not been studied in detail but is known to include insects and spiders. It typically forages singly or in pairs and seldom joins
Breeding
Nothing is known about the stripe-chested antwren's breeding biology.[4]
Vocalization
One description of the stripe-chested antwren's song is "a fast repetition of a musical phrase, 'chidu-chidu-chidu-chidu...' with up to 12 or so notes". Its call is "a doubled note followed by a short descending trill, 'chiwi-chrrrrrrt' ".[5] Other descriptions of its song and calls are respectively "a slow, even-paced, monotone series of musical couplets: tee-tip tee-tip tee-tip tee-tip tee-tip" and "a descending tew, quiet sick-sick notes, and ringing, harsh rattle".[4]
