Figure 1 The latency (s) for individuals to enter a novel
environment increased with age, suggesting a decrease in exploration
with age. The plot only contains data of individuals that left the box
and entered the novel environment during the 10 minute test period. This
corresponds to 29 of 50 individuals tested during incubation (black),
but only 18 of 58 individuals tested during the pre-laying period
(grey). Points represent mean latency and whiskers represent the
standard error. Sample sizes for each age-class and annual cycle stage
are presented in the plot.
Figure 2 Barplot showing the frequency of unreactive (black)
and/or reactive (grey) responses for each individual on extraction from
the nest. A higher proportion of reactive extraction scores were
recorded from migratory males compared to residents.
