mosambikapalis Apalis ruddi

A slender warbler that is gray and green above and pale below with a distinctive black throat band (narrower in the female), a short eyebrow, and a dark eye. Pairs are resident, occasionally joining flocks, in sand dune and riverine forest, thickets, and dense thorn scrub. The species is inconspicuous unless vocalizing: the male sings 5-15 rapid, repeated clucking “truk” notes that run together, and the female often joins in a duet with a more melodious trill. The similar Bar-throated Apalis differs from Rudd’s Apalis by having a pale eye and lacking an eyebrow.
