That was with a dose equivalent to eating only a few pesticide-treated seeds.

Morrissey also found that a pesticide found in dozens of commercial products left the birds with no idea of where north was.

Morrissey says her findings, published yesterday, may suggest why migratory songbird populations have been plummeting.

Health Canada is re-evaluating the use of some of the pesticides. (The Canadian Press)

(Brazil-Abortion)

In Brazil, a congressional committee has voted to make abortion illegal -- without exception.

Brazilian law currently allows abortions in cases of rape, when the mother's life is at risk or in cases of anencephaly, a birth defect involving the brain.

In practice, wealthy women tend to have access to safe abortions in private clinics, while the poor often rely on risky procedures.

An academic survey partially funded by the Ministry of Health estimates that more than 400 thousand women had an abortion in Brazil in 2015. …
