    Summary
    Recent work suggests that animals combine sounds in meaning-generating ways. Adding to this body of data, we demonstrate that pied babblers produce 2 variants of a stereotyped structure when recruiting group members during group travel, with internal acoustic variation refining the signal's meaning, specifying whether receivers should approach or follow the caller (i.e. come to/with me). Ultimately, examples of combinatorial mechanisms in nonhuman vocal systems can provide insights into the evolution of human language's combinatorial system.
