Acoustic niche partitioning operates through both spatial movement and temporal scheduling

Evidence

The mechanisms of partitioning may be either spatial or temporal. Spatial mechanisms require species to move in a way so as to not be masked by other concurrent species. Temporal strategies present more complex mechanisms: for instance, a temporal segregation (calling at a specific time of the day, e.g., dawn, dusk, midday), or a jamming avoidance (inhibition of calling when another species is calling at the same frequency band). — Almo Farina, Soundscape Ecology, 474
