10. Seed input relative to birds and vegetation
There was no correlation between numbers of observations of frugivorous birds and seed
input per month (r = 0.06, P > 0.05). The perches were, however, more attractive to birds when they
were taller than the surrounding vegetation. When other natural perches became available, artificial
perch use declined as a proportion of total plot usage. However, overall seed input appeared to increase
with time as the vegetation regenerated or the plantations matured (Fig. 7). Total seed input was greater
at perches than those at control points by a ratio of approximately 5.4:1. The ratio of seed input, perches
to controls was highest for plot 1 (927 to 1) and was lowest on plots 5 and 8 (1.5 to 1) (Table 4).
