Three subspecies are distinguished in the form, the range of which differs from one another, but they are all common in the countries of Central and South America [3] , where they inhabit subtropical and tropical low-lying , mountainous, and highly degraded forests , at an altitude of 600 to 1800 meters above sea level , sometimes up to 2250 meters above y. m. [4] [5] . The nominative subspecies is T. i. icterocephala , found in forests on the slopes, from the Pacific Ocean , eastern Peru in the province of Darien and the Andes in Colombia (in the department of Antioquia ) and western Ecuador (from the southern border to the provinces of El Oro and western Loja , inclusive), possibly in the northeast of Peru in the east of the Tumbes region [1] . Subspecies - T. i. frantzii - in the north-east of Costa Rica south to the slopes of the mountains of the province of Veraguas in western Panama [1] . T. i. oresbia - in the mountains of the province of Kokle and western Panama [1] .
Body length 13–13.5 cm [6] [7] , weight 18–25 grams [8] . The plumage is mostly golden yellow, with black yellow-bordered feathers on the back. Feathers of wings and tail are black with green bordering. The plumage of the throat is grayish-silver-white, on the side of the cheekbones delimited by a long narrow strip of black feathers [5] . Females from males are more dull in color, often having black stripes on their heads [5] . Immature individuals have even dimmer plumage [5] .

Adult males are not difficult to determine. Females and immature individuals are similar in females of Chrysothlypis chrysomelas , but differ from them in the striped plumage of the dorsal side and are always obscure by the white feathers of the throat [5] .
Voice
Voice signals consist of high, loud “jiit” and “dzrt” [6] [7] .
Active and inquisitive birds [7] . They move in the crowns of trees in the thick of foliage and jumping from branch to branch, in search of food [7] - fruits of various plants, including Miconia , ficus , Souroubea , Cecropia , as well as caterpillars and spiders and insects [9] . Birds can join other species on fruit trees, sometimes found in flocks from various species of small birds [5] [7] .
