This musical little bird, as one of its popular names implies, is partial to the neighborhood 

 of brooks, in search of insects. It builds its nest on the ground, laying 4-6 flesh-colored 

 eggs sprinkled with dark red at the larger end. It inhabits Louisiana, and as far south as 

 Brazil. It appears in this State from the south about the beginning of May, and has been 

 noticed as far north as the 64th parallel. It returns south through this State the latter end 

 of August, and appears to be equally fond of swamps and mountainous regions. I have not 

 been able to ascertain whether it breeds in this State.
