The Yemen warbler nests in bushes or trees, normally at a low height (2) (3). Mated pairs are monogamous and breed from March to July, although partners are thought to remain together for most of the year. Clutches typically contain three eggs (2).
The diet of the Yemen warbler consists primarily of insects, but fruits will also be taken when available. Feeding on nectar has also been suggested, although no detailed information exists on this (2).
