This hypothesis was tested by concurrent measurments of net insect emergence (total emergence minus adults returning to the stream) and densities of birds at six sampling sites from June to August 1987 and May to June 1988. Significant positive correlations with emergence were found for flycatchers (r=0.93) and gleaners (r=0.91), the two insectivore guilds containing the majority of individuals along Kings Creek. Observations also showed that flycatcher and gleaner populations rapidly respond to temporal changes in insect emergence.
