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...
Boater Compliance with Established Voluntary Waterfowl Avoidance Areas on the Upper Mississippi River
Disturbance to resting and feeding waterfowl on the Upper Mississippi River National Wildlife and Fish Refuge (Refuge) is of utmost concern to refuge managers. Voluntary Waterfowl Avoidance Areas (VWAA) have been established to reduce boating disturbance to migratory waterfowl on Navigation Pools 7 and 8 of the Upper Mississippi River. Ongoing boater compliance with the VWAA programs has been...
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...
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...
Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2024) Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2024)
The Deepwater Horizon oil spill on April 20, 2010 caused extensive injury to natural resources in the Gulf of Mexico, and Gavia immer (common loon) were negatively affected from the spill. The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill.

Satellite transmitters (Model PTT-100, Microwave Telemetry, Inc) were implanted in 31 adult male (marked during July 2010 and July 2011) and 27 juvenile (marked during August 2014 and August 2015)...
Lake Michigan Sea Duck Survey 2009-2014 Lake Michigan Sea Duck Survey 2009-2014
These data contain observation and null polygons for waterfowl aerial surveys of Lake Michigan collected through the years 2009-2014. Polygons were created adjacent to either side of the flight lines (transects). The right and left offset of the polygons from the flight path, was determined using the average altitude of the plane along the transect and the observation angle through the...

Restoration of Gavia immer (common loon) in Minnesota—2024 annual report Restoration of Gavia immer (common loon) in Minnesota—2024 annual report
In cooperation with the Minnesota Department of Natural Resources, the U.S. Geological Survey monitored 98 common loon (Gavia immer) focal territories and an additional 37 nonfocal territories in 2024 across 53 study lakes in Minnesota. Focal territories were those territories from which study inferences will be made, whereas nonfocal territories were observed to monitor common loon...

Dive characteristics of Common Loons wintering in the Gulf of Mexico and off the southern U.S. Atlantic coast Dive characteristics of Common Loons wintering in the Gulf of Mexico and off the southern U.S. Atlantic coast
Common Loons (Gavia immer) winter primarily in marine coastal areas and utilize a forage base that is poorly defined, especially for offshore areas. Information on dive activity is needed for describing foraging strategies and for inferring prey distribution. Archival geolocator tags were used to determine the wintering locations and dive characteristics of adult Common Loons captured...
