%X Primates rarely learn new vocalizations, but they can learn to use their vocaliza-
<br><br>tions in different contexts. Such ‘‘vocal usage learning,’’ particularly in vocal
<br><br>sequences, is a hallmark of human language, but remains understudied in non-hu-
<br><br>man primates. We assess usage learning in four wild chimpanzee communities of
<br><br>Taı
<br><br>
<br><br>¨ and Budongo Forests by investigating population differences in call ordering
<br><br>of a greeting vocal sequence. Whilst in all groups, these sequences consisted of
<br><br>pant-hoots (long-distance contact call) and pant-grunts (short-distance submis-
<br><br>sive call), the order of the two calls differed across populations. Taı¨ chimpanzees
<br><br>consistently commenced greetings with pant-hoots, whereas Budongo chimpan-
<br><br>zees started with pant-grunts. We discuss different hypotheses to explain this
<br><br>pattern and conclude that higher intra-group aggression in Budongo may have
<br><br>led to a local pattern of individuals signaling submission first. This highlights
<br><br>how within-species variation in social dynamics may lead to flexibility in call order
<br><br>production, possibly acquired via usage learning
