It kind of happens over night...
The duck population at the park goes from lots of drakes and hens,
To just a few of each. It's nesting season! Soon the little black and yellow striped ducklings appear with mom and dad.
Mostly guys on the pond...the ladies are on the nest down along the creek bank.
I came home from my walk, looked out at the pond and found...
this has never happened before, four in the pool at once. If two show up at the same time they fight...these four just sort of floated in formation, yellow eyes watching each other at all times.
Maybe they are a synchronized swim team?
