How to Identify Swallows

What Do Swallows Look Like?

Swallows are small birds, measuring 4 to 8 inches long. The most common species in Wisconsin are the cliff swallow and the barn swallow. Both species have a similar steel-blue coloration on their heads, backs, and wings, with lighter white plumage on their faces, chest, and underside. One main difference between the two species is their tails: the tail of the cliff swallow is squared, while the barn swallow has a long, forked tail.

Behavior & Habits

Swallows rarely enter houses, but they like to construct their mud nests on the exteriors of buildings. They only stay through the spring and summer before migrating south for the winter but will return to their nesting sites again the following spring. Swallows are fascinating birds to observe as they fly around, eating insects. They often hang around barns, bridges, and warehouses in large swarms.

What Problems Do Swallows Cause?

Swallows can damage property with their mud nests. While barn swallows tend to nest in small groups, cliff swallows may nest in large colonies. Nests positioned directly over doorways are hazardous because swallow droppings can fall on people and create a mess on walkways. Their droppings can also spread diseases and parasites, leading to major health concerns.
