Recently I have found it much more difficult to
locate Blue-faced Parrot-Finches on the southern Atherton
Tablelands, where they are common locally all year.
This is coincident with a
policy (by the Wet Tropics Management Authority ??) of spraying herbicide on
roadside grasses. In particular, the favoured Guinea Grass Panicum
maximum has been killed over many kilometres.
The paucity of finches may simply result from habitat
loss.
I would like to contact toxicologists that know whether
sprayed seed could have deleterious effects upon granivores. Presumably
the chemical used would be "Roundup" or its
equivalent.
