TORONTO - A huge proportion of Canada's bird species are in serious decline, threatened by disappearing habitat and climate change, the first comprehensive report on the health of the country's avian populations has found.
Overall, there's been a 12 per cent drop in bird populations since 1970, says the 36-page report, entitled The State of Canada's Birds 2012.
While some species have stayed at relatively stable levels over the last four decades — and some have even taken flight to a point — 44 per cent of Canada's 460-plus species have fallen in number, 66 of them so dramatically they are considered endangered.
