Stripe-necked tody-tyrant
The stripe-necked tody-tyrant is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia and Peru.
Taxonomy and systematics
The stripe-necked tody-tyrant has a complicated taxonomic history. It was originally described in 1853 as Todirostrum striaticolle. During different parts of the twentieth century it was placed in genera Euscarthmornis and Idioptilon, both of which were eventually merged into Hemitriccus. Also during parts of the twentieth century what are now Johannes's tody-tyrant and the white-eyed tody-tyrant were treated as subspecies of the stripe-necked tody-tyrant.The stripe-necked tody-tyrant has two subspecies, the nominate H. s. striaticollis and H. s. griseiceps. Some authors doubt the validity of the latter.
Description
The stripe-necked tody-tyrant is long and weighs. The sexes have the same plumage. Adults of the nominate subspecies have a grayish brown crown. They have a large white spot above the lores, a white eye-ring, and grayish brown ear coverts. Their back and rump are olive. Their wings are olive with indistinct yellow edges on the flight feathers. Their tail is olive. Their throat is white with distinct brownish streaks that continue onto the bright yellow breast. The rest of their underparts are mostly unstreaked bright yellow with a greenish tinge and diffuse darker streaks on the flanks. Subspecies H. s. griseiceps has a gray crown and duller green upperparts than the nominate. Both subspecies have a whitish to pale yellow iris, a blackish bill with a paler base to the mandible, and light gray legs and feet.Distribution and habitat
The stripe-necked tody-tyrant has a disjunct distribution. The nominate subspecies has by far the larger range. Its main population is found in central and southern Amazonian Brazil south of the Amazon from the Madeira River east to Maranhão and south to Mato Grosso, Goiás, and Minas Gerais states. That range continues west through northern Bolivia slightly into southeastern Peru's Madre de Dios Department. Small separate populations are also found in Peru's San Martín and Cuzco departments, in Colombia along the border between Meta and Guaviare departments, and in far eastern Brazil's Bahia state. Subspecies H. s. griseiceps has a very limited range along the lower Tapajos River in Brazil's western Pará state.The Amazonian population of the stripe-necked tody-tyrant primarily inhabits somewhat open landscapes including semi-humid to humid secondary woodland and thickets and bamboo along watercourses. In Colombia and parts of Peru it occurs in the undergrowth of wooded savanna. In elevation it ranges between sea level and in Brazil, up to in Colombia, and in Peru to in San Martín Department, in Cuzco, and only in Madre de Dios.
