Status designations and ranks for the Yellow Rail, at the global, national and sub-national levels, are given in Table 1.
The Yellow Rail is not listed by the International Union for the Conservation of Nature and Natural Resources (IUCN), although the closely related Swinhoe’s Rail (Coturnicops exquisitus) of Asia is considered Vulnerable (IUCN 1996). Some authors (e.g. Ripley 1977, Bookhout 1995) consider the Swinhoe’s Rail and the Yellow Rail the same species, while others consider them part of a holarctic superspecies (Olson 1973). The Nature Conservancy has expressed some concern for the Yellow Rail’s long-term global status by ranking it G4 (The Nature Conservancy 1998).
The Yellow Rail is listed as a Migratory Nongame Bird of Special Management Concern, which identifies migratory non-game birds that, without additional conservation action, are likely to become candidates for listing under the U.S. Endangered Species Act. This concern is based on its dependence on vulnerable or restricted habitats (USFWS 1995). It has concern status at the state level in all six states where it is known to breed (i.e., Oregon, Montana, North Dakota, Minnesota, Wisconsin, and Michigan), as well as in Idaho, South Dakota and Illinois (Table 1). It will likely be removed from the Endangered list in Illinois because it has not been found there in recent years during the breeding season, except for an unconfirmed 1998 record (J. Herkert, pers. comm.). It is ranked N3B, N4N for the U.S., meaning that it is rare or uncommon as a breeder, but as a non-breeder it is widespread, abundant, and apparently secure, albeit with concern for the long-term (The Nature Conservancy 1998).
Hunting this species is illegal throughout the U.S., but hunting of other rail species is legal in a number of states (J. Serie, pers. comm.).

The Yellow Rail is protected under the Migratory Birds Convention Act and accompanying regulations pertaining to hunting (Government of Canada 1989, Canadian Wildlife Service 1991). It is illegal to hunt rails anywhere in Canada, except in Ontario and in the Yukon. The bag and possession limits (all rails combined) in Ontario are 10 and 20, respectively (Canadian Wildlife Service 1998).
The Yellow Rail is considered a high concern species in Canada and a species with a very high Canadian supervisory responsibility score, reflecting the high proportion (about 90%; Figure 1) of its global range in Canada (Dunn 1997).
A new Northwest Territories endangered species legislation will allow for the protection of species at risk. For the time being, the territorial government relies on the COSEWIC list (L. Self, S. Carrière, pers. comm.). The Yellow Rail has no SRANK (see Table 1, footnote 2, for definitions of SRANKs; Figure 2).
The Nature Conservancy 1998.
This species is on the Yellow list (S. Cannings, pers. comm.), which includes indigenous taxa that are not considered to be at risk in British Columbia. Because it has not been determined to be present consistently, in which case it would be ranked S1, it is still ranked SA (S. Cannings, pers. comm.).
The Alberta government has designated 11 species as Endangered or Threatened under Alberta's Wildlife Act, but the Yellow Rail is not one of them. Its status in Alberta is “undetermined” because of insufficient information (Alberta Environmental Protection 1996). It is ranked S2S3B (J. Rintoul, pers. comm.).
Part 5 of the Saskatchewan Wildlife Act, "Protection of Wild Species at Risk", was proclaimed during the summer of 1997. No species are designated yet. Seven animal species are currently being considered for designation, but the Yellow Rail is not one of them. It is ranked S3 (J. Keith, pers. comm.).
The Endangered Species Act received royal assent on March 1990. Under this Act, 23 animal and species are listed as Endangered, Threatened or Extirpated; the Yellow Rail is not listed. It is ranked S4B, SZN (Duncan 1996). While it was estimated that there are likely more than 100 locations in Manitoba with suitable habitat, its presence and/or breeding has been documented at only a few of these (J. Duncan, unpublished data).
Twenty-four species are currently listed in regulation under Ontario's Endangered Species Act (I. Bowman, pers. comm.), but the Yellow Rail is not among them. It is ranked S3S4 (G. Van Drunen, pers. comm.). An Ontario status report recommended “Endangered” status for southern Ontario, and concluded that there was insufficient information for northern Ontario (Page and Cadman 1994, Austen et al., 1994).
No animal species have yet been designated under Québec's Loi sur les espèces menacées ou vulnérables, which was adopted in 1989. However, the Yellow Rail, considered vulnerable in Québec (Robert 1989), is one of 76 animal taxa listed on the Liste des espèces de la faune vertébrée menacées ou vulnérables susceptibles d’être ainsi désignées (List of Species Likely to be Designated Threatened or Vulnerable under the Act) (Gazette officielle du Québec 1993). Fortunately, it is being considered in all projects subjected to an environmental impact assessment under the Loi sur la qualité de l'environnement (Robert et al., 1995). It is ranked S2 (P. Aquin, pers. comm.).
The Yellow Rail has no official status in New Brunswick, nor was it reviewed by the former Endangered Species Committee. Nevertheless, there is concern (M. Sullivan, pers. comm.). It has not received an SRANK (S. Gerriets, pers. comm.).
An offical status evaluation has not been conducted because it is not known as a regularly breeding bird (M. Elderkin, pers. comm.). It has no SRANK (S. Gerriets, pers. comm.).
