Ornithology, also called birdlore, is a branch of zoology that concerns the study of birds several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds.

Migration is a necessary part of the survival of many types of birds during the winter, there is not enough food to sustain the many bird populations that depend on a constant supply of a variety of foods. Hybridization among bird species is a widespread phenomenon, which is best illustrated in estonia by the lesser spotted eagle and the greater spotted eagle however, due to the fact that the. The study finds the spring migration path follows a more roundabout route but the birds move faster thanks to the presence of strong tailwinds as they head north to their breeding grounds for species that do not fly over the open ocean, the study finds that many use the same migration routes in the spring and fall.

Birds migrate for several reasons migration is a necessary part of the survival of many types of birds during the winter, there is not enough food to sustain the many bird populations that depend on a constant supply of a variety of foods this lets birds know it is time to move on, or migrate, to another area that can meet their needs.

The seasonal migration of so many birds is an ecological puzzle there are about 10,600 known species of birds, and most don't migrate but about 15 percent of bird species go on these exhausting, heroic journeys , commuting thousands of miles between their summer breeding grounds and the places they spend the winter. The project is aimed to investigate 1) species-wise population monitoring and study the movement pattern of waterbirds within the lake and between the lake and their breeding grounds by using bird ringing and colour marking, 2) establish the correlation between the physico-chemical, benthic fauna and aquatic flora, 3) disease surveillance to establish the causes for avian diseases.

  • A study of 63 years of data for 96 species of bird migrants in canada showed that 27 species have altered their arrival dates significantly, with most arriving earlier, in conjunction with warming spring temperatures.
  • Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds many species of bird migrate migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food.

A study published monday in the journal nature ecology & evolution presents a model that explains, in a very big-picture way, the global distribution of birds the researchers say the reason for migration is surprisingly simple: it's all about energy efficiency birds are saving energy by flying thousands of miles. Migration is the regular seasonal movement, often north and south along a flyway between breeding and wintering grounds about 40% of bird species migrate migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food.
