Common loon winter dive data Breeding common loons for the movement and foraging pattern study were obtained from lakes in central and northern Minnesota and Wisconsin, and the Upper Peninsula of Michigan. Both adults of a territorial pair were fitted with archival geolocator tags (Model LAT 2500; 34.6 x 8.3 mm, 4.4 g; Lotek Wireless Inc.). A combination of adhesive and plastic cable ties were used to affix the geolocator tag to a modified lock-on aluminum leg band. Tags were programmed to collect daily location estimates for up to two years, tag temperature (0.02o C accuracy, ≤ 0.05o C resolution) at 30-min intervals, and pressure data (±1% accuracy, 0.05% resolution) at 20-sec intervals during daylight hours to document foraging patterns...

The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill. In 2020–21, study lakes in an eight-county region in north-central Minnesota were identified to focus project activities. In 2021 and 2022, surveys were conducted on these lakes to monitor common loon territory occupancy, nest success, and chick survival. This dataset includes a summary of total number of artificial nesting platforms (ANP), total number of ANP and natural nests, ANP and natural nest...

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) common loons that were captured on breeding lakes in Minnesota, Wisconsin, and the Upper Peninsula of Michigan. The satellite transmitters were programmed to transmit on a variable schedule based on the anticipated stage of migration during the loon’s annual cycle. We utilized the most accurate locations per 8-hour transmission period...
