eBird is a good resource for new birders.
You can see a list of Nebraska hotspots at this
link. This is for the entire state.
You can also view a map of hotspots at this
link. You can either zoom in on your location on the map, or enter your county and state in the "location" box. When you have zoomed in far enough you will see markers indicating how many species have been seen there. If you click on the marker you will get more information about the species seen there.
You don't have to be an member to use the "Explore Data" feature, but If you do join eBird it is a great place to keep track of what birds you have seen.
