Stripe-necked Tody-Tyrant
Hemitriccus striaticollis
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). 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. Voice: In Brazil the stripe-necked tody-tyrant's song is a "very high, fast, liquid, yet sharp 'Didrdr', 'Wic', or sweeping 'Wheet' ". What appears to be different song in Peru is "a loud, ringing, phrase...PEE-ti-ti-ti".
