THE COMPARATIVE ABILITY OF THE BOB-WHITE AND THE RING-NECKED PHEASANT TO WITHSTAND COLD AND HUNGER

摘要: THE native Bob-white (Colinus virginianus) and the introduced Ringecked Pheasant (Phasianus colchicus torquatus) may both, on occasion, suffer severe winter mortality over much of their common range in north-central United States. Their habitats often overlap, although has a greater cruising radius an ability to live more open type country than Bob-white. In given localities they also upon same kinds foods. The scope this paper is not intended cover ecological adjustments Pheasants or Bob-whites environment so as manifest effects cold malnutrition these birds under extreme conditions. Data which based were, for most part, obtained incidentally, connection with number field study experimental projects Iowa Wisconsin, chiefly between 1929 1934. Certain apparent hiatuses attributable incidental origin data would doubtless yield specifically directed experi? mentation, but latter I am position carry probably will be, at least some years come. meantime, it be biological interest possible value wildlife manage? ment summarize already available comparative hardiness Pheasants.
