GENUS BOTAURUS. HERMANN. 



27. Botaurus lentiginosus (MONTAG.). 

 American Bittern. 



A rare summer resident; sometimes tolerably common during the spring. It is 

 apparently restricted to the more extensive swamps and marshes on the bottom lands, 

 and to the vicinity of the larger bodies of water. 



GENUS ARDETTA. GRAY. 



28. Ardetta exilis (GMEL.). 

 Least Bittern. 



A tolerably common summer resident ; somewhat more numerous and more gen- 

 erally distributed during the spring migration. In the latter season it is occasionally 

 observed along streams or ditches on the bottom-lands. In summer it is apparently 

 confined to the ponds and lakes and to the secluded swamps. It was found to be not 

 uncommon at Round and Long Lakes, in Holmes County, just south of the Wayne 

 County line, on July 27, 1893. It undoubtedly breeds, though no nests have come to 

 the notice of the writer. 



Several years ago a Least Bittern was found dead on one of the streets of Wooster, 

 the bird having been killed by flying against the telegraph wires.
