“…This can be inferred, considering that, despite the lack of consumption of blue color seeds in some experiments (Hartley et al, 1999, 2000, Almeida et al 2010b) the use of carbofuran in the granular formulation of the same color has been banned in Virginia, USA and Canada, due to bird mortality caused by direct ingestion of the product (Almeida et al, 2010b). Moreover, there has been no communication observed between poisoned birds and healthy ones, that could stop the consumption, even when expressive mortality rates occur and in the presence of obvious agonistic behaviors caused by the ingestion of seeds treated with carbofuran, methiocarb carbosulfan or in combination with conspicuous colors such as beige and red (Almeida et al, 2010a;Almeida & Almeida, in press). In these experiments, it was noteworthy that gustative repellents (carbosulfan and methiocarb) were superseded by the fact that carbofuran has the unpleasant distinction of being so hazardous to wildlife, that it simply cannot be effectively regulated or managed accordingly without mortality risk occur (Richards & Mineau, in press).…”
