PASSERCULUS SAVANA : SAVANNA SPARROW. 239 



its favorite haunts being the salt marshes bordering the 

 sea-shore, but may be found in large numbers in any 

 open ground throughout the interior. I should not be 

 surprised to learn that it occasionally winters in shel- 

 tered places in the Connecticut valley ; but am not 

 aware that such is actually the case. The bird usu- 

 ally makes its appearance early in April, and soon be- 

 comes generally distributed. Many pass on to more

 from those of several other ground-nesters. When 

 caught in the act of incubation, the parent often flut- 

 ters and tumbles aloncj in the endeavor to attract atten- 

 tion to herself, and thus decoy the intruder away from
