Yellow-browed Tody-Flycatcher
Todirostrum chrysocrotaphum
The yellow-browed tody-flycatcher is 8.6 to 10 cm (3.4 to 3.9 in) long and weighs about 7 g (0.25 oz). The sexes are alike. Adults of the nominate subspecies T. c. chrysocrotaphum have a mostly black head with a white spot above the lores and a wide yellow supercilium that extends to the nape. A faint narrow yellow band separates their nape from their olive back, rump, and uppertail coverts. Their wings are black with yellow edges on the flight feathers. The wing coverts have thin yellow edges and wide yellow tips; the latter show as two wing bars. Their tail is black. Voice: The yellow-browed tody-flycatcher's song has been described as a far-carrying "series of sharp emphatic 'tsip' notes" numbering eight to twelve. Another author describes it as "an easily overlooked, insectlike high, accelerating chipping series: tchit... tchit... tchit tchit tchit tchit-tchit-tchit-tchit-tchit".
