The secondary objective (Objective 2) was to compare historical (1978-1979) and recent (2010-2015) data on bird use at sites that were surveyed during both sampling periods. Both objectives involve comparisons, objective 1 contrasts R2R and reference sites using contemporary data, while objective 2 compares contemporary data with those sampled in the 1970s; albeit the latter with slightly different methodologies.enSt. Louis River Freshwater EstuaryBeneficial use impairmentBird countsBird samplingBird migrationNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
