Cormorant Culling
Cormorant culling is the intentional killing of cormorants by humans for the purposes of wildlife management. It has been practiced for centuries, with supporters of culling generally arising from the angling community. Culling techniques may involve the killing of birds, the destruction of eggs, or both. Historically, culls have occurred to protect the interests of recreational and commercial fishermen who perceive the animals to be competing with them for their intended catch or for the prey of their intended catch. Since the 1960s, the growing aquaculture industry has undertaken cormorant culls to protect its farmed fish and crustacean stocks. Opponents of cormorant culling include conservation groups such as the National Audubon Society, Cormorant Defenders International and Sea Shepherd. Target species The target species are primarily the double-crested cormorant in North America and the great cormorant in Europe, Japan, and Australia. The little black cormorant has also ...

Double-crested Cormorant (Phalacrocorax Auritus)
The double-crested cormorant (''Nannopterum auritum'') is a member of the cormorant family of water birds. It is found near rivers and lakes and in coastal areas and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring in length, it is entirely black except for a bare patch of orange-yellow facial skin and some extra plumage that it exhibits in the breeding season when it grows a double crest in which black feathers are mingled with white. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like all cormorants, are not waterproof, and it must dry them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years. Taxonomy The double-crested cormorant was described by René Primevère Lesson in 1831. It was formerly classified in the genus ''Phalacrocorax'', but a 2014 study supported reclassif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpshooters
A sharpshooter is one who is highly proficient at firing firearms or other projectile weapons accurately. Military units composed of sharpshooters were important factors in 19th-century combat. Along with "marksman" and "expert", "sharpshooter" is one of the three marksmanship badges awarded by the United States Army and the United States Marine Corps. The United States Navy and the United States Coast Guard use a ribbon with an attached "S" device to note a sharpshooter qualification. Military sharpshooter history American Revolutionary War and War of 1812 Some of the earliest mentions of rifling and sharpshooting units in the United States originate during around the American Revolutionary War and the War of 1812. During the 1777 battles of Saratoga, Continental Army officer Benedict Arnold strategically arranged for sharpshooter units to target enemy officers and artillery units. All such sharpshooters units were disbanded following the war's end in 1783, but they were la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
