I think like any state it has a lot to do with the winter/spring/summer weather. We all know that even 10 miles can make a big difference in weather and how the birds handle it. It also has a lot to do with the pockets of habitat, if you find large areas with good habitat or counties with large amounts of habitat I think that plays on in the bird numbers you see in the survey results.Anecdotally between eastern iowa and NW IA, I have not really been seeing any more birds than any time the past 5 years either out driving or running the dogs. I hope they are right, but I'm not convinced yet. I think it will be a good year regardless, but I don't think it is as good as the DNR believes.
No question. From talking with folks in the DNR who do the surveys, it does sound like they had several routes along poor habitat that usually prodcue just a few bird sightings that produced multiples of that this year.I think like any state it has a lot to do with the winter/spring/summer weather.
