Restoration of Common Loons in Minnesota

During the breeding season (late March to early September), common loons can be found in the northern United States, and portions of Alaska and Canada. Common loons nest in lakes that range in size from 12 acres to over 10,000 acres. Nests are generally found near shore in a protected bay or in the lee of islands. Common loons prefer to nest on clear lakes with abundant small fish and are...

Wetland Loss: Modeling Consequences for Waterfowl Production, Recreation Use, and Economic Opportunities

Amendments to the Clean Water Act in 1972 established federal jurisdiction over “navigable waters,” defined in the Act as the “waters of the United States.” A revised definition of the Waters of the U.S. rule took effect on 20 March 2023. However, various legal challenges precluded implementation of the new definition. On 25 May 2023, the U.S. Supreme Court, in the case of Sackett et ux. v...

Common Loon Migration Study

Common loons often migrate several hundred miles to reach coastal waters during fall migration. Information about this part of the loon's life history is not well known. The use of satellite telemetry allows biologists to track loon movements through distant migrations and during winter. A transmitter attached to a radiomarked loon periodically sends a signal which is detected by a satellite-based...

Waterbird Distribution and Foraging Patterns on the Great Lakes with Respect to Avian Botulism

The Upper Midwest Environmental Sciences Center (UMESC) in La Crosse, Wisconsin is studying the distribution and foraging patterns of sentinel fish-eating waterbirds through aerial surveys, and by tracking migration movements coupled with foraging depth profiles of common loons equipped with archival geo-locator tags and satellite transmitters. The results of this work are expected to elucidate...

Assessing the Potential for Climate Change Impacts on the Suitability of Inland Glacial Lakes for Lake-Dependent Biota in the Great Lakes Region

Climate change models predict warmer temperatures, changes to precipitation patterns, and increased evapotranspiration in the Great Lakes region. Such climatic changes have altered, and are expected to further alter hydrological, chemical, and physical properties of inland lakes. Lake-dependent wildlife are often sensitive to changes in water quality, and are particularly susceptible to lake...

Evaluating Habitat Use by Pelagic Birds on the Western Great Lakes, and Airspace Use of Migrant Songbirds Near and Over the Western Great Lakes.

This assessment deals with a select geographic area, the Upper Great Lakes, and the common birds that can be found there during migration periods. Much is known about potential landbird stopover habitats and raptor migration routes, and a great deal of GIS data is available to develop preliminary risk models for landbirds. However, the distribution, abundance and species composition of waterbirds...
