Stripe-necked Tody-Tyrant

The stripe-necked tody-tyrant (Hemitriccus striaticollis) 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.

Also during parts of the twentieth century what are now Johannes's tody-tyrant (H. iohannis) and the white-eyed tody-tyrant (H. zosterops) were treated as subspecies of the stripe-necked tody-tyrant. The stripe-necked tody-tyrant has two subspecies, the nominate H. s. striaticollis (Lafresnaye, 1853) and H. s. griseiceps (Todd, 1925). Some authors doubt the validity of the latter. == Description == The stripe-necked tody-tyrant is 11 to 12 cm (4.3 to 4.7 in) long and weighs 7.8 to 11 g (0.28 to 0.39 oz).

Their back and rump are olive. Their wings are olive with indistinct yellow edges on…
