Figure 2.

Seasonal changes on Wicken Fen in the proportion of reed warblers that (A) were parasitized by cuckoos; (B) mobbed an adult cuckoo model at the nest; and (C) rejected nonmimetic model eggs, with week 1 beginning May 14. White circles (with short dashed lines) represent data from 1985 to 1986, gray circles (with long-dashed lines) represent data from 1996 to 1997, and black circles (with solid lines) represent data from 2010 to 2012. Circle diameters are relative to sample size and an x-axis jitter of 0.1 was applied to display overlapping data.
