Abstract
In many bird species the total song repertoire consists of an overt reperto ire normally uttered, and a silent repertoire produced only under special c ircumstances. A silent repertoire can be inferred from specific vocal respo nses of an individual to hearing parts of its own silent repertoire uttered by another bird ('sympathetic song'). The silent repertoire plays a promin ent role in dueting birds, in particular those with sex-specific overt song repertoires, where the overt repertoire of one partner is the silent reper toire of the other. This is here exemplified with a pair of the slate-colou red boubou L. funebris. Silent repertoires should be taken into considerati on when relating the complexity of birds' vocal behaviour to the size or st ructure of their forebrain vocal control areas.
