Where do starlings prefer to nest?

Starlings prefer to nest in cavities and on buildings due to their adaptability and opportunistic nesting behavior. They are known to utilize various structures created by humans, such as eaves and vents, as well as natural cavities found in trees or rock formations. This preference for elevated nesting sites helps protect them from ground predators and provides a suitable microclimate for raising their young.

In contrast, options like water bodies and open ground do not offer the protection or structural benefits that starlings seek for nesting. While they may occasionally forage near water or on the ground, these environments do not align with their nesting preferences. The choice to nest only in trees is also too restrictive, as starlings are not limited to that habitat and often thrive in urban and suburban settings where buildings provide ample nesting opportunities.
