Legend to figures:
Figure 1: Temporal distribution of broods of each focal host species
along the breeding season. Data from 8 consecutive breeding seasons.
Blue dots and red triangles represent non-infected and infected broods,
respectively. Week 0 refers to the week of the spring equinox (September
in the southern hemisphere). Pi. sulphuratus (Great Kiskadee) is
the optimal host, Ph. sibilatrix (Little Thornbird) the bad
alternative host and Ph. ruber (Greater Thornbird) the good
alternative host.
Figure 2: Predicted burdens of first instar larvae (L1) on bad
alternative hosts (Little Thornbird) (a and b ) or good
alternative hosts (Greater Thornbird) as a function of host demand
(parasite abundance) and the co-existing number of broods of optimal
hosts (Greater Kiskadee) (a and c ) and good
alternative hosts (b ).
