Figure 3
The effect of model egg treatment on corticosterone levels. Females
experimentally parasitized with non-mimetic beige eggs (n=21) did not
differ in baseline corticosterone levels compared to females
experimentally parasitized with mimetic blue eggs (n=22). Black dots
indicate females that had had not rejected the egg within two hours,
while red dots indicate females that rejected the egg. Within the
non-mimetic egg treatment, females that rejected and accepted the eggs
did not differ in their corticosterone levels.
