Popis:	We studied the breeding biology of Grasshopper Sparrows (Ammodramus savannarum) on restored grasslands in Maryland from 1999 to present. We report the first documented cases of social polygyny in this species. Polygyny increased reproductive success for males in two of four cases, but its rarity suggests it is only a facultative behavior for this usually socially monogamous species
