We camped near a cliff and took the opportunity to get some bonus rope practice happening. To our surprise we found some empty Cliff Swallow nests made of mud.
Cliff swallow nests are made up of 900-1200 mud pellets. They are a fairly social bird with a non-forked tail (barn swallows have forked tail) They are mostly insect eaters.
