Mist Net
Mist nets are used by hunters and poachers, but also by ornithologists and chiropterologists to capture wild birds and bats for banding or other research projects. Mist nets are typically made of nylon or polyester mesh suspended between two poles, resembling a volleyball net. When properly deployed in the correct habitat, the nets are virtually invisible. Mist nets have shelves created by horizontally strung lines that create a loose, baggy pocket. When a bird or bat hits the net, it falls into this pocket, where it becomes tangled. The mesh size of the netting varies according to the size of the species targeted for capture. Mesh sizes can be measured along one side of the edge of a single mesh square, or along the diagonal of that square. Measures given here are along the diagonal. Small passerines are typically captured with 30–38 mm mesh, while larger birds, like hawks and ducks, are captured using mesh sizes of ~127 mm. Net dimensions can vary widely dependin ...

Bird Hunting
Fowling is the hunting of birds by humans, for food ( meat), feathers or any other commercially value products, or simply for leisure ("sporting") or collecting trophies. It is comparable to wildfowling, the practice of hunting waterfowls for food or sport. The term is perhaps better known in the Fens of Eastern England than elsewhere, but was certainly not confined to the Fens. The land margins of the north produced down feathers from eider duck for eiderdowns and quilted jackets without necessarily killing the birds. In the Western Isles of Scotland, seabirds were taken from their nests on cliffs. In The Fens and other similar places, a decoy was part of a landowner's well-equipped estate. The epitome of fowling was, however, the punt gunner. He had what amounted to a long, small-bore muzzle-loaded cannon. It was mounted along the centre-line of the forward half of a specially designed boat which slightly resembled a heavy wooden kayak in form. The fowler lay in the after ...

Ornithological Equipment And Methods
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bal-chatri
Bal-chatri (/bɑːl tʃʌθri/) are traps designed to catch birds of prey (raptors). The trap essentially consists of a cage baited inside with a conspicuously visible live rodent or small bird, with a series of monofilament nooses attached to the surface to snare the legs of a free-flying raptor that attempts to take the bait. The name is derived from the Hindi word used by trappers in India. Modified bal-chatri traps are also used for catching shrikes. History The bal-chatri originated in East India as a trap developed and used by falconers to catch suitable birds of prey to train for use in hunting. It consisted of a small, conical, cane cage, containing live lure birds to attract raptors, and covered with attached horsehair nooses to entangle their feet. The term bal-chatri ( hi, बाल छत्री) has been mistranslated as “boy’s umbrella”, or “small umbrella”, after their shape but is correctly translated to "hair umbrella" and refers to the nooses made ...

Ecosystem Management
Ecosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ecosystems function and services while meeting socioeconomic, political, and cultural needs. Although indigenous communities have employed sustainable ecosystem management approaches for millennia, ecosystem management emerged formally as a concept in the 1990s from a growing appreciation of the complexity of ecosystems, as well as humans' reliance and influence on natural systems (e.g., disturbance, ecological resilience). Building upon traditional natural resource management, ecosystem management integrates ecological, socioeconomic, and institutional knowledge and priorities through diverse stakeholder participation. In contrast to command and control approaches to natural resource management, which often lead to declines in ecological resilience, ecosystem management is a holistic, adaptive method for evaluating and achieving resilience an ...

Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frog ...
