Lily,
Cliff Swallows nest colonially, often in large numbers. Along the Denali Hwy, Alaska nearly every bridge has a colony of Cliff Swallows nesting under the bridge. This is a picture I took of a Cliff Swallow colony in an 8 foot diameter culvert under the Denali Hwy, on Tuesday. This is an unusual location for a colony, I have ever seen nests in a culvert before.
