The winter birds were not singing the spring songs as loudly today in the mostly cloudy day. The red-winged blackbirds are often one of earlier arrivals as well as robins and killdeers. This killdeer can blend in with a plowed field and lays its eggs in a depression in the dirt (or cow pie) but right now the fields are still covered in snow. So it may be a few more weeks before seeing any spring arrivals.
