DOUBLE-CRESTED CORMORANT VS. RED-NECKED GREBES, COLONEL SAMUEL SMITH PARK, TORONTO, ON

   In the first five photos you can see the two mated Red-necked Grebes peacefully building their nest.  They are bringing twigs for the nest.  Then all of the sudden a Double-crested Cormorant lands on the nest and tries to chase them away.  It actually throws some of the nest back into the water.  Meanwhile the Grebes continue to bring twigs to the nest.  We never did see the end of this saga.
