Industrious Cliff Swallows

A patch of mud near a nesting colony produces Cliff Swallows fluttering like butterflies to keep their wings clean while they gather gooey construction material.

Cueing up in orderly fashion.

Here is a description from the Cornell Lab of Ornithology about their nests. The nest is a covered bowl made of mud pellets, with a small entrance tunnel on one side. Lined with grass. It is placed on a vertical wall, usually just under an overhang.

Even their tails are carefully held high and clear of the mud.

A charismatic and tough little bird. I’ll go back to check on them in a few days.
