Koford 1954 Cynomys ludovicianus December 17, 1954 Mr. Wellington, Colorado. contained a colony of prairie dogs, perhaps 50 in number according to Crawford, that probably had never been poisoned. I saw at least 4 separate dogs out although the day was overcast and the wind strong (temp. 40°). One dog was tame tho it had never been handled. It walked up to Crawford who fed it corn. This one named "Charlie." Charlie walked about a well-fored burrow mound. Mound showed no recent construction. An animal seen 50 yds. from Charlie. Another dog was named "Good Eye." Crawford said that recently, he saw him go down a burrow carrying a mouthful of grass. Crawford had seen prairie dogs drink and was sure that they had wells down to water. He thought, from some digging experience, that the tunnels spiralled down. He had slept pets when a dog. The pup, with head upfat with body straightened upward, was a sign to others that everything was all right. Others did it after seeing it done. (I saw Charlie & an animal do it). A sharp chit-chit, a double note, was an alarm call that caused all to go underground. We thought that occasionally an old one was driven out of a colony as he had sometimes seen one wandering far from a colony. This colony apparently not poisoned because no one was interested. Rabbit brush common in area. That in colony kept clipped lawn. Not grazing here for 4-5 years, according to Crawford - but trampling by people & car tires. Colony on gentle W.-facing slope. Lower edge flat ground,
