Cliff Swallows Gathering Mud for Nest building

Yesterday I noticed much active behaviour and wing fluttering of a small bird species around a mud puddle and decided to take some pictures to attempt to discover what was taking place.  It didn't take long to realize it was a small group of Cliff Swallows gathering mud to build a nest which I discovered in the eaves of a house nearby  where a cliff swallow house was being constructed.
The many pictures below need few words to describe the action.
