anthropogenic processes. Metals such as Fe, Mn, and Li were either correlated with natural input or with anthropogenic activities. Concentration of heavy metals such as Cd, Pb, and Cr were well above the threshold level that can cause adverse effects in birds and pose menace to the cattle egrets population in Pakistan. The study suggested that the feathers of cattle egret could be used as a bio-monitor of the local heavy metals contamination. Keywords Heavy metals Á Multivariate analysis Á

B.A.S.H. Bird Aircraft Strike Hazard The first documented bird strike was made by Orville Wright during a flight near Dayton, Ohio in 1905. Bird strikes have caused millions of dollars in damages to aircraft and loss of human life. Calbraith Rodgers, the first pilot to fly across the continental United States, ironically was also the first to die as a result of a bird strike. In 1912, he struck a gull, causing his plane to crash into the water at Long Beach, California. Recently bird strikes have

term duck decoy may refer to two distinct devices, both used for hunting wildfowl. One is a long cone-shaped wickerwork tunnel installed on a small pond to catch wild ducks. After the ducks settled on the pond, a small, trained dog would herd the birds into the tunnel. The catch was formerly sent to market for food, but now these are only used to catch ducks to be ringed and released: see ornithology. The word decoy, also originally found in English as "coy", derives from the Dutch de kooi (the cage)

Behaviour- nesting: Swallows are excellent fliers, and use these skills to attract a mate and to feed. Some species, like the Mangrove Swallow, are territorial, whereas others are not and simply defend their nesting site. In general, the males select a nest site, and then attract a female using song and flight, and (dependent on the species) guard their territory. The size of the territory varies depending on the species of swallow; in colonial-nesting species it tends to be small, but it may be

aviation industry by the Wright Brothers (2005) has seen a massive change in its structure and functioning. As technology advanced more convoluted are the efforts to carry on this gigantic trade of huge mechanical birds on the sky, which nevertheless have to share the natural domain of the birds. One of the major concerns of the aviation industry is also contributed by the obstacles faced to minimize hazards (2012) of wildlife on the human terrain without harming the natural territory. Through this review

Wings of birds and bats: the only two vertebrates known to fly; however, they share no close ancestor. This is known as convergent evolution in which unrelated species, such as the bird and bat, have developed similar structures in flight but their skeletal structures are very different (McGhee, 2002). The two biological and obvious differences are the bat’s wings, which are made up of a leathery skin membrane with hair and fur, while bird wings have feathers. The wingspans also differ in each
