One of four Mottled Duck ducklings I saw together with no mom in sight.
Perhaps the mom has gone missing. If so, the ducklings are perfectly capable of feeding and caring for themselves. But they are more vulnerable to attacks by predators.
Hopefully mom will return. Or the ducklings will attach themselves to another family.
My best to you ducklings and while waiting for help to arrive, stick together ... there is safety in numbers.
