Where the differences in habitat and climate are so great there are many changes of habits, and some of them of a noteworthy kind. Mr. John A. McIlhenny, of Avery’s Island, Louisiana, formerly a lieutenant in my regiment, lives in what is still a fine game country. His plantation is in the delta of the Mississippi, among the vast marshes, north of which lie the wooded swamps. Both the marshes and the swamps were formerly literally thronged with whitetail deer, and the animals are still plentiful in them. Mr. McIlhenny has done much deer-hunting, always using hounds. He informs me that the breeding times are unexpectedly different from those of the northern deer. In the North, in different localities, the rut takes place in October or November, and the fawns are dropped in May or June. In the Louisiana marshes around Avery’s Island the rut begins early in July and the fawns are dropped in February. In the swamps immediately north of these marshes the dates are fully a month later. The marshes are covered with tall reeds and grass and broken by bayous, while there are scattered over them what are called “islands” of firmer ground overgrown with timber. In this locality the deer live in the same neighborhood all the year round, just as, for instance, they do on Long Island. So on the Little Missouri, in the neighborhood of my ranch, they lived in exactly the same localities throughout the entire year. Occasionally they would shift from one river bottom to another, or go a few miles up or down stream because of scarcity of food. But there was no general shifting. On the Little Missouri, in one place where they were not molested, I knew a particular doe and fawn with whose habits I became quite intimately acquainted. When the moon was full they fed chiefly by night, and spent most of the day lying in the thick brush. When there was little or no moon they would begin to feed early in the morning, then take a siesta, and then—what struck me as most curious of all—would go to a little willow-bordered pool about noon to drink, feeding for some time both before and after drinking. After another siesta they would come out late in the afternoon and feed until dark.
