Bird migration - Wikipedia, the free encyclopedia Migratory species in these groups have great difficulty crossing large bodies of water, since thermals can only form over land, and these birds cannot maintain active flight for long distances. Those species which have no long-distance migratory relatives, such as the waxwings, are effectively moving in response to winter weather, rather than enhanced breeding opportunities. The northernmost populations, however, are nomadic rather than migratory, as are the Silvereyes of southern Western Australia, which is bounded by thousands of miles of desert to the north and east, and sea to the south and west. en.wikipedia.org /wiki/Bird_migration   (2311 words)

Migratory Pollinators Introduction In order to protect these migratory corridors, it is crucial to develop local public acceptance of the conservation needs and opportunities identified by this project. They are the migratory routes that pollinators follow in order to take advantage of a sequence of plants coming into bloom along a south-to-north gradient in the spring and the reverse in the fall. Ample nectar sources along monarch migratory corridors are crucial for monarch survival in their wintering grounds in the south and breeding grounds in the north. www.desertmuseum.org /pollination/introduction.html   (1882 words)

Migratory Bird Conservation: Director's Priorities FY1999-2000 The Migratory Bird Management Program (coordinated by the Office of Migratory Bird Management in conjunction with regional and field offices) and the North American Waterfowl Management Plan (coordinated by the North American Waterfowl and Wetlands Office in conjunction with many partners) are the traditional stalwarts of migratory bird conservation for the Service. Migratory birds are somewhat unusual in the animal world in that they range across thousands of miles during their annual cycle. Migratory birds are an excellent indicator of the overall health of an ecosystem. training.fws.gov /history/priorities/priomig.html   (4158 words)

Welcome to the DNR Division of Fish and Wildlife Web Site It is illegal to hunt migratory birds (ducks, geese, coots, mer-gansers, doves, woodcock, sora, moorhens or snipe) with a shotgun capable of holding more than three shells, unless it is plugged with a one-piece filler that cannot be removed without disassembling the gun. Migratory game birds may be hunted from a motorboat provided it is beached, resting at anchor, tied to a stationary object, or without motion other than that imparted by wind and current acting upon the hull, or due to hand-operated oars or paddles. No person shall ship migratory game birds unless the package is marked on the outside with: (a) the name and address of the person sending the birds, (b) the name and address of the person to whom the birds are being sent, and (c) the number of birds, by species, contained in the package. www.in.gov /dnr/fishwild/huntguide1/waterfowl.htm   (1729 words)

Migratory Birds When the weather warms in the Northern Hemisphere, migratory birds leave their wintering grounds in Mexico, Latin America, and the Caribbean, where they have benefited from abundant food and a warm climate during the winter months. The term "migratory route" indicates the general direction of flight that is annually followed by migrating birds on their journeys to and from wintering and breeding grounds. Neotropical migratory bird: A bird which moves seasonally between temperate regions of the Americas, where it spends its breeding time, and tropical areas, where it spends the months when it's winter in the north. learning.turner.com /efts/species.970730/miglead2.html   (3284 words)

Migratory birds   (Site not responding. Last check: 2007-10-22) Migratory bird import & export restrictions between Mexico & the U.S. were also authorized,& in issuing any regulations to implement this section, the Secretary of Agriculture was required to consider U.S. laws forbidding importation of certain mammals injurious to agricultural & horticultural interests. The Secretary was required to consider the related migratory bird conventions with Great Britain, Mexico,Japan, & the Soviet Union in establishing these regulations & to establish seasons to provide for the preservation & maintenance of migratory bird stocks. P.L. 105-312, Migratory Bird Treaty Reform Act of 1998, amended the law to make it unlawful to take migratory game birds by the aid of bait if the person knows or reasonably should know that the area is baited. pages.zdnet.com /sirp/myyard/id10.html   (879 words)

News and Views - Press Releases - Migratory Bird 9-11-98 Under current law, only hunting migratory birds over a baited field is illegal; the act of baiting the field is not. The Migratory Bird Treaty originally passed in 1918 to provide for the protection of migratory game birds by making it illegal to hunt, kill or capture birds except as permitted by government regulations. In the United States, that regulatory agency is the Fish and Wildlife Service, which annually sets the hunting season and "bag limits" and prohibits certain hunting activities, such as the use of recorded bird calls or live decoys or the use of shot that is toxic to waterfowl. www.house.gov /snyder/news_views/press_releases/pr980911.html   (312 words)

Audubon: Coffee and the Conservation of Migratory Birds   (Site not responding. Last check: 2007-10-22) Traditionally, coffee was grown under a canopy of shade trees, providing critical wintering habitat critical to many species of migratory birds and preserving the rich biodiversity inherent in tropical rainforests. Increasingly, however, industrial coffee farms, where land is cleared of its lush vegetation to grow coffee in full sun, are replacing traditional coffee farms. With this conversion from traditional shade-grown to industrial sun-grown coffee comes a corresponding decrease in migratory bird species, and this decrease in species diversity is dramatic -- over 90% fewer bird species are found on sun-grown coffee farms than on shade-grown coffee farms. www.audubon.org /bird/cafe.html   (284 words)

Migratory Birds and Spread of West Nile Virus in the Western Hemisphere Despite the fact that migratory birds have long been suspected as critical agents in outbreaks of this and other arboviruses, the link remains conjectural because of the difficulty in determining the intensity and duration of viremia in naturally infected wild birds (8,9). Furthermore, although the virus may remain enzootic for years awaiting environmental conditions that favor an epidemic (36), the usual pattern in southern Eurasia is one of isolated outbreaks, apparently resulting from importation of active virus by migratory birds into an area with appropriate climatic, vector, and amplifying host conditions (7). Although this group includes many migratory birds that breed in eastern North America, only approximately 12 species (Table 2) could serve as carriers for West Nile virus, because most migrate alone and do not gather in large roosting or feeding flocks in the winter or during migration (46). www.cdc.gov /ncidod/EID/vol6no4/rappole.htm   (4420 words)

Migratory Bird Overview The term "migratory route"indicates the general direction of flight that is annually followed by migrating birds on their journeys between wintering and breeding grounds. Because of the reduced land area available to northern migrants in wintering verses breeding grounds, the destruction of 100 acres of habitat in the tropics may have the same effect as a 1,000-acre loss of forest in the north. International Migratory Bird Day is designated as the Partners in Flight program's annual, keystone event to raise awareness of migratory birds through communications, outreach, and education programs. learning.turner.com /efts/species/migover.html   (2324 words)

Rules & Regulations | Migratory Game Bird & Waterfowl Hunting Doves are migratory game birds, so federal rules of shotguns plugged to hold no more than three shells are in effect. All migratory game birds killed or crippled shall be retrieved, if possible, and retained in the custody of the hunter in the field. No person shall give, put or leave any migratory game birds at any place or in the custody of another person unless the birds are tagged by the hunter with the following information: name and address, the total number of birds of each species and the date of kill. www.agfc.com /rules_regs/hunting_regs_migratory.html   (1596 words)

Conservation Ecology: Modeling the geography of migratory pathways and stopover habitats for neotropical migratory birds Modeling the geography of migratory pathways and stopover habitats for neotropical migratory birds. Intact migratory routes are critical for the stability of forest-dwelling, neotropical, migratory bird populations, and mortality along migratory pathways may be significant. Intact migratory routes are critical for survival (Hutto 2000), and mortality during migration may be significant (Moore and Aborn 2000), yet we know almost nothing about which stopover habitat types are most important or how their distribution and quality define intact migratory pathways (Moore and Simons 1992). www.ecologyandsociety.org /vol7/iss1/art7/main.html   (4855 words)

Frequently Asked Questions about Migratory Birds Migratory birds are those species that generally migrate south each fall from breeding grounds to their wintering grounds. Migratory birds are definitely in the majority in contrast to resident birds that do not migrate, such as Rock Doves, European Starlings, and House Sparrows. All migratory birds are listed as a trust species for the Department of the Interior according to the Migratory Bird Treaty Act of 1916. migratorybirds.pacific.fws.gov /FAQs.htm   (1493 words)

KY: Kentucky Dept Fish and Wildlife - Migratory Game Bird Permit Wildlife biologists and hunters have noted that populations of migratory game birds, such as dove and woodcock, have declined in recent years. Because migratory birds are a shared resource among many states, the harvest information program will be implemented across the country by 1998. Migratory Game Bird Survey Cards must be filled out prior to purchasing either a Kentucky Migratory Game Bird Permit or a Kentucky Waterfowl Permit. www.kdfwr.state.ky.us /migrperm.asp?lid=593&NavPath=C162   (874 words)

Migratory Bird Treaty Act of 1918 Migratory bird import and export restrictions between Mexico and the U.S. were also authorized, and in issuing any regulations to implement this section, the Secretary of Agriculture was required to consider U.S. laws forbidding importation of certain mammals injurious to agricultural and horticultural interests. Activities aimed at selling migratory birds in violation of this law would be subject to fine of not more than $2000 and imprisonment could not exceed two years.

Maine Department of Inland Fisheries and Wildlife - Migratory Waterfowl Stamps   (Site not responding. Last check: 2007-10-22) A Maine Migratory Waterfowl Hunting authority is required of anyone age 16 and over who hunts waterfowl in Maine. This year’s subject was the bufflehead duck, and Alley’s rendition of a pair of buffleheads flying over an early morning marsh garnered the most points from the panel of judges on March 28th at the Augusta Civic Center. Migratory waterfowl hunters 16 years of age and older no longer need to purchase the state migratory waterfowl stamp and affix it to their license, instead they must purchase the authority on their check-off license. www.state.me.us /ifw/wildlife/duckstamp.htm   (1137 words)

WDFW -- Migratory Waterfowl and Upland Game Regulations Migratory bird stamps are now part of validation stickers attached to licenses issued by automated licensing terminals.

Migratory Birds and the Convention on Migratory Species Migratory birds face a multitude of threats during migration. By their very nature, migratory species have become a symbol for the need of international efforts in nature conservation. The Contracting Parties cooperate to conserve migratory species and their habitats by providing strict protection for endangered migratory species, listed on Appendix I, by concluding multilateral agreements for the conservation and management of migratory species, listed in Appendix II, and by undertaking co-operative research activities. www.birdlife.org /action/change/cms   (504 words)

MIGRATORY BIRD CONSERVATION ACT: Summary from Federal Wildlife Laws Handbook This Act establishes a Migratory Bird Conservation Commission to approve areas of land or water recommended by the Secretary of the Interior for acquisition as reservations for migratory birds. The Migratory Bird Conservation Commission is created and authorized to consider and act on recommendations of the Secretary of the Interior (Secretary) for the purchase or rental of land, water, or land and water for the conservation of migratory birds. The Secretary may not recommend an area for purchase or rental under the Act unless the Secretary has determined that the area is necessary for the conservation of migratory birds and has consulted with the county in which the area is located and with the governor of the state concerned, or the appropriate state agency. ipl.unm.edu /cwl/fedbook/mbca.html   (697 words)

EPA: Federal Register: Migratory Bird Permits; Take of Migratory Birds by Department of Defense This means developing knowledge of migratory bird habits and life histories, including their migratory paths and stopovers as well as their feeding, breeding, and nesting habits. To proactively address migratory bird conservation, the Department of Defense should engage in early planning and scoping and involve agencies with special expertise in the matters relating to the potential impacts of a proposed action. At the Department of Defense's request, the Service will provide technical assistance in identifying the migratory bird species and determining those likely to be taken as a result of the proposed action, assessing impacts of the action on migratory bird species, and identifying appropriate conservation measures to mitigate adverse impacts. www.epa.gov /fedrgstr/EPA-IMPACT/2004/June/Day-02/i11411.htm   (9820 words)

Migratory Birds In Europe and North America, migratory birds were at the centre of the earliest examples of transnational environmental negotiation (Lyster 1985; Churchill, 1995). Throughout the twentieth century, increased knowledge of migratory patterns and expansion of conservationist concern led to growth in the scope of cross-border links among government wildlife agencies, NGOs, and scientific organizations. Is there evidence that transnational migratory bird arrangements have led to the emergence of de-centralized, multi-level governance institutions "in which actors are no longer motivated by their particular national loyalites and identities, but by collective principled and causal beliefs as well as by the goals of the institution" (286)? web.uvic.ca /~polisci/wilson/research/bird/proposal.htm   (3198 words)

WDFW -- Washington State Migratory Bird Stamp and Artwork Program Migratory bird habitat in Washington sustains our breeding population of ducks, geese, mourning doves, band-tailed pigeons, and other migratory birds, but also numerous other birds that breed in Alaska, western Canada and even Russia. Revenue from the sale of stamps to hunters and collectors is dedicated to buy and develop migratory bird habitat, and to enhance, protect, and produce migratory birds in the state. Migratory bird stamps are a double investment - investing in habitat and also in collectible stamps which appreciate in value over the years. wdfw.wa.gov /wlm/game/water/duckstmp.htm   (410 words)

Migratory Bird Treaty Act under Attack The Migratory Bird Treaty Act is a domestic measure that was passed in 1918 to protect birds during their migration. Now, 86 years later, some Members of Congress have decided that some species of migratory birds are pests to be killed en masse, despite the fact that the MBTA already includes a mechanism for addressing specific problems that may arise in particular locations. Notwithstanding the appalling notion of killing certain species of migratory birds, this legislation is being rushed forward without any scientific study being conducted to assess the validity of claims that some of these 94 species of birds may be harming their environment. www.saplonline.org /Legislation/108/hr4114.htm   (369 words)

Climate Change Linked To Migratory Bird Decrease Migratory Songbirds Have A Specialized Night-vision Brain Area (May 24, 2005) -- Neurobiologists have discovered a specialized night-vision brain area in night-migratory songbirds. Migratory Songbird Breeding Linked To Winter Habitat (December 7, 1998) -- For several decades, scientists studying the population dynamics of migratory birds have debated the relative importance of events in summer breeding areas versus tropical wintering grounds. The migratory behavior of bird populations can change in only a few generations, and several populations of wrens, skylarks and other short-distance migrants have stopped migrating in the last 20 years. www.sciencedaily.com /releases/2003/03/030326073630.htm   (595 words)
