A few years ago this pair of mallards raised 12 little ducklings on our little landscape pond. You can see the brood they raised in a blog post on June 2, 2010.
In the time since I've glimpsed them occasionally, but this year they are back, strutting around the front landscape staking out their territory.
I think they are fierce enough to keep Dickens at bay and defend their nest. I'm hoping to see a clutch of fuzzy yellow ducklings sometime soon.
