LENGTH four inches and three quarters, breadth eleven ; 

 weight half an ounce. Bill blackish ; irides hazel ; plumage above 

 mouse-colour, beneath white ; on the breast a bar of mouse-colour ; 

 tail a trifle forked, the outer feather being eight lines longer than the 

 two middle ones, and the wings exceed the end of it by five lines; 

 legs blackish, and feathered behind. 



Male and female much alike. — This is the smallest of our Species, 

 and frequents the banks of rivers, and sand pits, where it excavates 

 horizontal holes in the sides, at the end of which is the nest ; these 

 are frequently two feet or more in depth, but not always in a straight 

 line, for in many instances they are serpentine, owing perhaps to the 

 intermixture of hard nodules in the sand, or earth, through which it 

 is less easy to penetrate, and turning at intervals a little aside to avoid 

 them : sometimes have been known to build in old quarries, and 

 walls, and even in the hollows of trees ; the nest is composed of a 

 few dried fibres or straw, mixed with feathers ; it is said to breed 

 only once in a year, laying five or six white, transparent eggs; and 

 to produce its young more early than any of its tribe.
