Millie and Roy are constantly on the lookout for predators. In the summer of 2015, ravens were the most common threats in the early season and a cross-fox was a frequent visitor in June and July.
On July 20, the ducks raised a noisy alarm with one mother duck attacking something in the tall grass. We suspect that the fox had "harvested" a duckling close to the shore in Bog Central.
Millie and Roy signalled Arrow to "Flee and Hide" and came to Bog Central on Tall Alert. They used running Droop Wing displays to pursue the fox across Bog Central, into the underbrush, and out of their territory.
This is part 5 of Millie and Roy's 2015 nesting chronicle.
