Zippy?

I don't know if anyone remembers Zippy and Skippy and their mom "Yellowcheeks" from 2012? Here's a photo of them at about 2-3 weeks old:

I lost track of them when Zippy found a mate and I thought she left the lake for good. However, I recently came across an old photo of Zippy that made me realize something. This isn't the old photo, but it's a photo that I'm completely sure is her, so I am posting it. Sorry for the contrast.

Here is the photo I came across this morning that was taken about eight months after the one above.

I just realized that Zippy may be the mother of the two ducklings from near the parking lot earlier this year. They're the ones that the grebe family liked to follow around.
