Here's one of Hissy and Seraphim's babies... this year, they managed to raise three. They are as big as their parents, but still retain the brown feathers of their babyhood, and make little squeaky toy noises when they get near.
Hissy, the mom, doesn't mind when they swim near, but Seraphim, the dad, will drive them away almost as rivals or as though they are invading his territory. They look confused and don't seem to know what to do.
I haven't seen the kids in the past few days, they may have had to fledge completely and move on to another lake before moving South for the winter. Hissy and Seraphim have stayed at Avalon and have been busy eating, no doubt building up stores for the winter.
