day this species still nests where it has for years in the chasm 

 called " Purgatory " at the westerly end of the Second Beach,

 inaccessible crevices of the vertical walls, where they usually

 rock. Np Cliff Swallows {Petrochelidon lunifrons) breed in this 

 chasm, a place apparently more suited to them, than to the Barn 

 Swallows.
