Ducklings

Saw these eight ducklings (funny triangular forms in photo on right) at the weekend near the willow tree in the pond. Today I could only see one chick but maybe it was another batch. But then where are the other ducklings?

And where, BTW, are the kingfishers? I haven't seen them for 2 weeks, whereas for the last few months I'd see them every time I visited the site. Has anyone seen them recently?
