This warbler is endemic to Jamaica. Adults have its namesake arrowhead-like streaking, while first-year birds have a different plumage and lack that pattern.
Adults have black-and-white streaks forming arrowheads from throat to abdomen, plus two white wing bars. Females are similar to males but have greyer streaks; first-year birds are olive-brown with yellowish-buff underparts and lack the arrowhead pattern.
It occurs in woodland and forest from near sea level into humid uplands, usually low in thick foliage or tangled undergrowth. It probes branches, leaves and vines for insects.
An extinction-risk assessment has not been added yet.
In a survey of Cockpit Country, Jamaica, Arrowhead Warblers were associated with sites where forest disturbance was lower.
