Temporal Pattern Shifts to Avoid Acoustic Interference in Singing Birds

Temporal Pattern Shifts to Avoid Acoustic Interference in Singing Birds

Two species of forest birds, the least flycatcher and the red-eyed vireo, when breeding in the same season in the same habitat, adjust their temporal pattern of singing to avoid the overlapping of songs. The avoidance of acoustic interference is more marked in the flycatcher, which has a briefer son...

The avoidance of acoustic interference is more marked in the flycatcher, which has a briefer song than the vireo.
