Figure 4: Change in jackdaw nestling body mass from day 5 to
day 30 in reduced (left panel) and enlarged broods (right panel). Raw
means and confidence intervals (bars) are shown for all individuals
(black), or separately for unparasitized (N, grey) and parasitized (Y,
grey) nestlings. The interaction between brood size manipulation andCarnus infestation did not significantly affect mass change.
