Great crested grebe (possibly a female) on Pool House fishing lake with three recent chicks last weekend.
One chick is swimming behind her. Slightly larger than the others, it probably hatched first. The other two, which also have the striped, “tapir-patterned” plumage, are on her back.
The other adult, presumed to be the male, was staying in one position on the water a little further away, watching that this group were safe.
