Bird–window Collisions
Bird–window collisions (also known as bird strikes after the Bird strike, aviation term or as window strikes) are a problem in both low- and high-density areas worldwide. Birds strike glass because reflective or transparent glass is often invisible to them. It is estimated that between 100 million and 1 billion birds are killed by collisions in the United States annually, and an estimated 16 to 42 million birds are likewise killed each year in Canada. Window collision variables The issue of bird-window collisions has become more prevalent as wild habitat is lost. It has intensified as landscaping and exterior glass continue to become more popular. However, due to differences within the taxon, built environments, time of year, and other effects, there is great variation in the nature and frequency of collisions. Susceptible species Studies analyzing window collisions across greater spatial scales reveal interesting trends in species composition, indicating that some birds ar ...

Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
