Huge flocks of Red-breasted Mergansers
are feeding on Lake Ontario in Durham Region between Frenchmans Bay
in Pickering and Rotary Park in Ajax. These videos give an idea of
the size of the flocks. There must be an abundance of minnows,
but how long will they last with so many birds. Frenchmans Bay on 20
November 2017. Hoping the Northern Gannet will come by to check out
the food supply.
