Bird Migration Perils
Migrating birds face many perils as they travel between breeding and wintering grounds each year. Migration is a dangerous part of a bird's life cycle, with many trade-offs; birds receive benefits from wintering and breeding in better quality habitats, at the price of higher predation risks and greater energy expenditure. Hazards during migration include storms, hunting, collisions with manmade objects such as wind turbines, and starvation. The risk of starvation is increased when stopover sites are lost through climate change or loss of habitat to development or agriculture. Mortality on both breeding and wintering grounds may be increased for similar reasons. Context Migrants tend to travel away from polar and temperate zones in the winter because of low temperatures and shortage of food in their breeding areas.Newton, I.

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...

Migratory Birds Convention Act
The Migratory Birds Convention Act (also MBCA) is a Canadian law established in 1917 and significantly updated in June 1994 which contains regulations to protect migratory birds, their eggs, and their nests from destruction by wood harvesting, hunting, trafficking and commercialization. A permit is required to engage in any of these activities. History In 1909 the federal government established the Advisory Board on Wildlife Protection, which notably included C.G. Hewitt and James Harkin as prominent members. This board would go on to sign the Migratory Bird Convention with the United States because of concern both countries had regarding the uncontrolled hunting of waterfowl and shorebirds. The original MBCA law was passed to satisfy the terms of this agreement with the United States. The updated version includes stronger enforcement and greater penalties. A geographical area may be designated as a ''Migratory Bird Refuge'' under this convention; this restricts activities targe ...

Migratory Bird Treaty
The Migratory Bird Treaty Act of 1918 (MBTA), Codification (law), codified at (although §709 is omitted), is a United States federal law, first enacted in 1918 to implement Migratory Bird Treaty, the convention for the protection of migratory birds between the United States and Canada . The statute makes it unlawful without a waiver to pursue, hunt, take, capture, kill, or sell nearly 1,100 species of birds listed therein as bird migration, migratory birds. The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs, and nests. A March 2020 update of the list increased the number of species to 1,093. Some exceptions to the act, including the eagle feather law, are enacted in federal regulations (), which regulate the taking, possession, and transportation of bald eagles, golden eagles, and their "parts, nests, and eggs" for "scientific, educational, and Depredation permit, depredation control purposes; fo ...

Common Pochard
The common pochard (; ''Aythya ferina'') is a medium-sized diving duck. The scientific name is derived from Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ''ferina'', "wild game", from ''ferus'', "wild". Description The adult male has a long dark bill with a grey band, a red head and neck, a black breast, red eyes and a grey back. The adult female has a brown head and body and a narrower grey bill-band. The triangular head shape is distinctive. Pochards are superficially similar to the closely related North American redhead and canvasback. Females give hoarse growls. Males have whistles cut off by a final nasal note ''aaoo-oo-haa''. Distribution and habitat Their breeding habitat consists of marshes and lakes with a metre or more water depth. Pochards breed in much of temperate and northern Europe and across the Palearctic. They are migratory, and spend winter in the south and west of Europe. In the British Is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufted Duck
The tufted duck or tufted pochard (''Aythya fuligula'') is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and ''Latin'' ''fuligo'' "soot" and ''gula'' "throat". Description The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks. In particular, some have white around the bill base which resembles the scaup species, although the white is never as extensive as in those ducks. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo". The onl ...

Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Swan
Swans are birds of the family (biology), family Anatidae within the genus ''Cygnus''. The swans' closest relatives include the goose, geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe (biology), tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life, although "divorce" sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of bird egg, eggs in each :wikt:clutch, clutch ranges from three to eight. Etymology and terminology The English word ''swan'', akin to the German language, German , Dutch language, Dutch and Swedish language, Swedish , is derived from Indo-European root ' ('to sound, to sing').
