The Importance of Nesting Habitat for Common Loons

Loons rely on specific lakeshore habitats to successfully nest and raise their young. These magnificent birds prefer to nest offshore, away from mammalian predators, while staying close to the water’s edge for a quick escape route. However, climate change poses significant challenges to their nesting habitat, necessitating conservation efforts to protect them from its effects.

Changes in climate patterns, such as extreme precipitation events and droughts, can disrupt loon nesting habitat. Flooding caused by heavy rains can flood nests, destroying eggs and endangering the nesting loons. Similarly, drought conditions can lead to the drying up of traditional nesting sites, making them unsuitable for loons to reproduce.

In certain years, loons face another obstacle known as blackfly infestations. These tiny, blood-sucking insects can drive loons away from their nests, forcing them to abandon their breeding efforts and decreasing their chances of successful reproduction.

Moreover, the warming of Wisconsin lake waters due to climate change raises concerns about the impact on loons. It remains uncertain how high temperatures loons can tolerate and how changes in water temperature might affect their nesting behavior and reproductive success.
