I live in a semi-rural area with several lakes with waterfowl on, quite close to my house. Usually there are lots of ducklings and goslings around by now, but I've only seen three ducklings this year and they were on a pond in a town. The more rural ponds have plenty of adult ducks and geese swimming around in pairs, but no babies.
Has anyone else noticed this? Is it bird flu? Could the warm weather have somehow affected breeding success?
