The American kestrel population in Yukon has dropped by about 90 per cent over the past decade

A well-known Yukon bird biologist says kestrels, the smallest member of the falcon family in North America, are rapidly disappearing from the territory. Dave Mossop says the American kestrel (Falco sparverius) population in Yukon has dropped by about 90 per cent over the past decade. He says the decline is about 65 percent in North America overall. “This is a little bird that sits at the top of the food web in which it lives,” he said. “And so, depending as it does on the whole system below it, it becomes a wonderful indicator species of things that are changing.”
