'' on behalf of the Association for the Protection of the Adirondacks, Marshall successfully persuaded the court to uphold the Migratory Bird Treaty Act of 1918, between the United States and Canada. As characterized by Adler, Marshall argued, "the United States did have the power to create such legislation; that Congress was well within its rights; and that the Act was constitutional"; and, further, "If Congress possessed plenary powers to legislate for the protection of the public domain, then it had to take into account all possibility for such protection", including protection of migratory birds, "these natural guardians" against "hostile insects, which, if not held in check ... would result in the inevitable destruction" of "both prairie and forest lands". According to Handlin, Marshall's intervention "was a major factor in the decision."

'') threw out what has been dubbed the migratory bird rule. A case that pitted a consortium of towns around Chicago over isolated wetlands, inhabited or visited by over 100 migratory bird species, against the US Army Corps of Engineers. In this case, Skokie, Illinois, wanted abandoned quarries filled with water, but not connected to another or navigable body of water to serve as a site for a solid waste facility. For the previous 15 years, lower courts had sustained the law in favor of migratory birds, siding with the Army Corps. At least one state reacted to the new Supreme Court ruling by restoring isolated wetlands protection: 2001 Wisconsin Act 6, is the first of its kind nationwide to restore wetlands regulation to the state after federal authority had been revoked. It restores protection to over one million acres (4,000 km²) of isolated wetlands in Wisconsin. On May 7, 2001, Wisconsin Governor

signed a bill protecting wetlands by placing Wisconsin wetlands regulation under the jurisdiction of the Wisconsin Department of Natural Resources. Bipartisan state legislators fully supported the bill and felt it was necessary after the Supreme Court ruled that the federal clean water act didn't give the corps authority over decisions involving isolated wetlands.

. The Migratory Bird Treaty Act of 1918 prohibits the removal of all listed species or their parts (feathers, eggs, nests, etc.) from such property. However, in extreme circumstances, a federal permit might be obtained for the relocation of listed species (in some states a state permit is required ''in addition'' to a federal permit). Pursuant to the spirit of the treaty, it is not trivial to obtain a permit; the applicant must meet a certain criteria as outlined in Title 50,

, 21.27, Special Purpose Permits. The permit applicant is generally a contractor who specializes in wildlife relocation. When hiring a contractor to trap and relocate any animal from one's property, the private property owner is well advised to attain proof of such permits before any trapping activity begins, as trapping without the necessary paperwork is common in the United States. Most wildlife management professionals consider relocation actions undue harm to the birds, particularly since relocated birds (being migratory) often return to the same property the next year. In the case of trapping and relocation, ''harm'' is brought on by or can result in: * ''Breaking'', a term describing increased susceptibility to disease brought on by the stress of capture and relocation * Difficulty in establishing territory at the new location * Separation of family members and the stunting of juveniles' natural progression into adulthood


Game birds and hunted species

The migratory bird conventions with Canada and Mexico define "game birds" as those species belonging to the following families: *
Anatidae The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating ...

Charadriidae The bird family Charadriidae includes the plovers, dotterels, and lapwings, about 64 to 68 species in all. Taxonomy The family Charadriidae was introduced (as Charadriadæ) by the English zoologist William Elford Leach in a guide to the con ...

(pigeons and doves). The Migratory Bird Treaty Act, which implements the conventions, grants the Secretary of the Interior the authority to establish hunting seasons for any of the migratory game bird species listed above. In actuality, the Fish and Wildlife Service has determined that hunting is appropriate only for those species for which there is a long tradition of hunting, and for which hunting is consistent with their population status and their long-term conservation. It is unlikely, for example, that we will ever see legalized hunting of plovers, curlews, or the many other species of shorebirds whose populations were devastated by market gunners in the last decades of the 19th century. Although the Migratory Bird Treaty Act considers some 170 species to be "game birds," less than 60 species are typically hunted each year. The Fish and Wildlife Service publishes migratory game bird regulations in the Federal Register. Those species for which hunting regulations have been established at some point during the past 10 years are designated with an asterisk (*) in the following list. However, such a designation does not necessarily indicate that a given species can be taken legally in your State or locality. For regulations specific to your locality, you should consult with your State's natural resource agency. Source: The list of hunted species was taken primarily from Appendix 2 of the Final Supplemental Environmental Impact Statement: Issuance of Annual Regulations Permitting the Sport Hunting of Migratory Birds (SEIS 88), U.S. Fish and Wildlife Service.

to "take migratory birds during a 'military readiness activity.'" (Readiness activities are defined as all training activities and military operations related to combat and the testing of equipment for combat use.) The record in congress noted that "A recent federal court ruling indicated that the Navy had violated the Migratory Bird Treaty Act by incidentally taking migratory birds without a permit during training exercises near Guam. The House report indicates that the exemption provision is intended to address the lack of permit authorization for incidental takings, so that essential training exercises may proceed. It appears that the language used in the bill would not authorize the issuance of permits, but more broadly would state that the part of the Migratory Bird Treaty Act that articulates unlawful behavior does not apply to a military readiness activity.
