The mean weight of the 51 galls preyed upon by birds (1.31g with standard error ±0.06g and standard deviation ±0.46g, range 0.4g-2.4g) was larger than the mean weight of the 33 galls that were not preyed upon by birds (1.12g with standard error ±0.06g and standard deviation ±0.32g, range 0.4g-1.8g, p=0.0304) (Figure 4). The mean weigh of the galls preyed upon by birds was found to be significantly larger than the weight of the galls not preyed upon by
