Figure 1. Seasonal reproductive success of bluebirds as a function of fire ant abundance.

Figure 1

Relationship between fire ant abundance (mean number of ants captured per sample vial) and the seasonal reproductive success (total number of fledged offspring) of eastern bluebirds (R 2 = 0.17, F 1, 31 = 5.98, p = 0.02). Each point represents a single territory (n = 31).
