Changes in animal protection policies could make the future of migratory birds in the air.


The trump administration has announced that birds are being used to protect migratory birds from the current policy in the past 100 years.
In 1916, during the chaos of the first world war, President Woodrow Wilson and king George v of England signed the treaty of passage. Two years later, the migratory bird agreement act (MBTA) wrote the treaty into American law. In addition to the license or regulated hunting is allowed, these measures through the illegal hunting, killing, capture, kill or sell live bird or dead birds, feathers, eggs and nests to protect more than 1100 species of migratory birds.
This bold move was caused by a decrease in the number of birds in North America. About five million birds, especially waterfowl like egrets and herons, die every year, putting on hats for their feathers, which have become extinct. Fearing the same fate for other species, the leaders took action.
Now the ministry of the interior has issued a legal opinion, side by side to explain this behavior in addition to “accidentally take” activities, these activities are not to hurt the birds, but to do so in the foreseeable way directly, such as wetland in migratory birds to rest and feed. Why is that? For fear of “unlimited potential for criminal prosecution”. As the argument points out, the owner of a cat who attacks a migrant bird or a driver who accidentally hits a bird with a car may be charged with a crime.
But MBTA does not execute this way. Major negligence cases that apply to prospective and avoidance of potential hazards, such as the dumping of toxic pesticides into a pond used by migratory birds. The new legal interpretation means the company will avoid legal liability and liability for killing millions of birds each year.
Pollution, development and habitat loss kill birds.
Targeted killings are just one of many threats to migratory birds. Habitat loss, invasive species, pollution and colliding with buildings impose heavy tolls on many species. According to the U.S. fish and wildlife service, more than 40 million birds are killed each year by industrial activities or buildings (such as power lines, oil Wells, communications towers and wind turbines). The deepwater horizon oil spill in the gulf of Mexico in 2010 killed more than one million birds in an incident.

Each of the 17 former home office officials who represented Nixon through Obama’s administration wrote a memo expressing deep concern about the new policy. As they explain, MBTA provides a powerful incentive for the industry to work with government agencies to predict, avoid and mitigate predictable deaths or damage to birds.
For example, it has prompted energy companies to install nets in places where oil drilling waste is stored. Because these pits look like water, birds tend to land on them, and may get into trouble and die. Installing a net on the pit will reduce the annual death rate of birds of about two million birds to between 500,000 and a million. Imperfect, but meaningful improvement.
Global citizens, global consequences.
Because migratory birds do not recognise international borders, reinterpreting MBTA’s consequences could cross national borders. In one year, a warbler may spend 80 days in Canada’s boreal forest, spend 30 days in the United States, rest and refuel during the migration, and spend 200 days in Central America.
In the Cornell laboratory of ornithology, we used volunteers to build maps and animations for data collected by eBird, the world’s fastest growing biodiversity database. These references indicate how migratory birds are connected to the state. Many people spent a year across the western hemisphere.
For example, the eastern breeding of the yulan orioles in the Yucatan peninsula and Central America winter, its temperature in a small part of its breeding range. Seeing the density of these birds in their winter habitat shows that every acre of our land is important to their survival.
In the same way, most of the population of western bovine liver bacteria in the west is wintering in Mexico. In this way, the winter habitat of birds is determined, and we can better protect species during the entire annual cycle.
