Alright, time to bump this one up.
The bulk of the Central Flyway's birds seem to be hung up in Montana and the Dakotas. While some nasty weather in September and October pushed down quite a few the majority are still up north, with reports that even the prairie provinces are still holding good numbers of birds.
I'm not saying that Wyoming, Nebraska, Colorado, Iowa and Missouri don't have birds but they don't have all their birds yet. It's gonna take some cold weather to push down the rest and kick the migration into high gear.
If I could travel to kill birds my itinerary would include Eastern Montana, NoDak, SoDak and Northern Nebraska right now... I wouldn't turn down a trip to Central Wyoming either.
Just the skinny from my neck of the marsh... what have you heard?
