Not climate-related, as the species experiences far colder and snowier conditions in parts of its native range. The reason why released Pheasants don't breed well is that they've never had a natural parental upbringing - so they don't even know what to do with those round things that come out of their back ends, let alone know how to care for the chicks and protect them from predators :eek!:Thank you all (espacially aeshna5) for mentioning the (regular?) nesting of Pheasants, at least in Britain (and Russia?). That was new to me, but I must admit that I dont massve experience with this topic.
In Germany, Pheasants are generally believed to rely on released birds to sustain a stable population over a longer period (even in "good" habitats with a mild, snowfree winter climate).
