644 Lake Maxinkuchee, Physical and Biological Survey 



The deep, sonorous, bull-like bellow of this frog can be heard 

 about some portion of the lake shore throughout the summer. They 

 usually are heard toward the southeast shore of Lost Lake 

 where the miry shore and fringe of rushes give them good pro- 

 tection. During the summer of 1906 one kept bawling almost 

 every day from the neighborhood of the ice-houses. They keep 

 up their bawling from May 1 to as late as August 26. 



Like the Green Frog, the Bullfrog rarely strays far from the 

 water, but stays by the shore, ready to jump in at the slightest 

 alarm. There are few animals hunted more persistently than 

 these. They are captui'ed by several methods — by shooting, by 



Bullfrog (Rana catesbeiana) 



use of acetyline light, and by the use of red flannel on fishhooks at 

 which they readily jump, so that in spite of the almost inaccessible 

 bits of shore they frequent, they are unable to hold their own. 



The Bullfrog is said to be very voracious, and is reported to 

 capture and swallow young ducklings. On account of its rarity 

 at the lake, little was learned of its habits. 



The Bullfrog can usually be identified by its size and voice. 

 The following short description will assist in identifying speci- 

 mens : 



Greenish, of varying shades, with small faint dark spots above; 

 head usually bright pale green ; legs blotched ; tympanum large ; toes 

 broadly webbed; femur equal to tibia, not half body. Length 5 

 to 8 inches.
