Black-headed Tody-Flycatcher
Todirostrum nigriceps
The black-headed tody flycatcher is a small bird with a glossy black head and a white throat. The black coloring continues down the sides of the neck. It has bright yellow underparts and olive-yellow upperparts. The wings are black with two yellow wingbars and yellow streaking and the tail is short and black. Its head is relatively large, as is its straight black bill. It has dark irises and no eye-rings. Its legs are blueish-gray. The females and males have the same coloring. Adults are between 8–10.2 cm long and weigh 6–6.5 g. Voice: This species' call is a single high-pitched "peep". Its song is a series of 5 to 8 high-pitched "jyip" notes that are quickly repeated. They start evenly spaced and accelerate slightly at the end, increasing in pitch slightly. It often calls repeatedly, which can be easily confused with their song. The chirps also sound insect-like.
