A few weeks ago I read that almost a million mallards were on the Missouri river in S. Dakota, then that really cold arctic blast hit with ice, sleet and snow. It didn't look like snow it the Dakotas, Nebraska or Kansas but got really cold. So I am wondering have the mallards left S. Dakota or not. I'm sure some did and we get spotty reports of them in Nebraska, Kansas, Oklahoma and Texas. Did they keep flying over Oklahoma or are they still north? This fall I drove through Kansas and could not believe all the agriculture with abundant rainfall over summer...so that makes me think they are feeding and using big water.
The past two years the mallards never really migrated south due to lack of heavy (6+ inches) snowfall that prevents them from feeding in fields.
What you say?
