In 2008 we had 2 downy chicks on the back of mom on the 1st of October.
In that year the pair produced four clutches starting in May.

Unfortunately, no pied-bill grebes nested on Green Lake in 2010. One
pair nested four times in 2009. We think that only one chick survived
into the fall. In 2008 there were four pair nesting on the lake. Prior
years had as many as a dozen pairs nesting on Green Lake.
