Tree Swallow 11 O’clock
Tree Swallow, bogey at eleven o’clock high. This aerial acrobat streaked in fast, wings cupped and eyes locked, moments before committing to a fiercely contested birdhouse during the spring nesting rush.
Worth Noting
The popularity of bluebird nest boxes has inadvertently benefited Tree Swallows, which nest in cavities of nearly identical size and readily claim these artificial sites. In areas without abundant nest boxes, Tree Swallows must compete with other cavity-nesting birds, often arriving early in spring to secure territories. Unlike many other swallows, they also eat berries—especially bayberries—allowing them to survive cold snaps when insects are scarce. (Source: Audubon)
