The names ''jay'' and ''[[magpie]]'' are somewhat interchangeable, and the evolutionary relationships are rather complex. For example, the [[Eurasian Magpie]] seems more closely related to the [[Eurasian Jay]] than to the Oriental [[Urocissa|Blue]] and [[Cissa (magpie)|Green Magpies]], whereas the [[Blue Jay]] is not closely related to either. ==Systematics and species== ''See'' classification box for relevant [[genus|genera]] links. Traditionally, the [[Crested Jay]] (''Platylophus galericulatus'') is placed here, but apparently this is not correct, as suggested by anatomical and molecular evidence{{Fact|date=February 2007}}. Its placement remains unresolved; it does not seem to be a corvid at all. It should be noted that according to the research of Ericson ''et al.'' (2005), jays are not a [[monophyletic]] group. Rather, they can be divided into an [[Americas|American]] and an [[Old World]] lineage (the latter including the [[ground jay]]s and the [[Piapiac]]), while the [[gray jay]]s of the genus ''Perisoreus'' form a group of their own. The [[Black Magpie]], formerly believed to be related to jays, is classified as a [[treepie]].

The term ''[[jaywalking]]'' was coined in 1915 to label persons crossing a busy street carelessly and becoming a traffic hazard. [http://m-w.com/dictionary/jaywalker] Eventually the behavior became defined as illegal in many communities in the USA. Eventually, traffic control regulations were introduced that would levy a fine against pedestrians who were not using the delineated crosswalks marked on streets, but rather, cutting across traffic where they pleased. A public relations campaign began in the 1950s as the new regulations were introduced in Manhattan and many communities across the country instituted similar laws. Rarely is the regulation exercised. The term began to imply recklessness or impertinent behavior as the convention became established.
