The coots built the first nest, which eventually contained 10 eggs.

The grebes started building their nest next to it later on. Several grebe eggs fell into the water because they were lying on the edge or were crushed during fights with the coots.

After this brief skirmish, the grebes chased the coots away.

The number of eggs in the coot’s nest decreased, but now I saw that the grebe had laid two in her own nest.
