Chris had me post this: "August is grasshopper season in Hays, and on 11 August 08 I was watching Roscoe hunt down grasshoppers when he displayed a behavior I had not seen before. I had dumped five grasshoppers, including one large winged adult about 2½ inches long, into Roscoe's cage. Roscoe hunted down three of the smaller grasshoppers and stopped to bask in the lamplight and lick his lips. Meanwhile, the large winged grasshopper was motionless on the gravel near the water dish in the dimly lit corner of the cage about 33-36 inches away from Roscoe's head. Roscoe was alert with his head elevated and stayed that way for a few minutes. Suddenly Roscoe jerked his head up another quarter inch and it was obvious to me that he had suddenly recognized the motionless grasshopper. He dropped his head, quickly moved forward about fifteen inches to peek at the grasshopper while largely hidden behind a large piece of driftwood. Immediately, Roscoe began excitedly twitching the distal five inches of his tail side to side in a cat-like manner. After perhaps a second of twitching, he sprinted to the grasshopper, which tried to get away, but landed in the water dish and was quickly caught by Roscoe. I found the combination of the flash of recognition that that motionless green blob over there was a grasshopper followed by the almost cat-like stalking and pounce behavior remarkable." Mmmm, grasshoppers! |
