Page "Ornithology" Paragraph 36

Organizations were started in many countries and these grew rapidly in membership, most notable among them being the Royal Society for the Protection of Birds ( RSPB ) in Britain and the Audubon Society in the US.

The Audubon Society started in 1885.

Both these organizations were started with the primary objective of conservation.

The RSPB, born in 1889, grew from a small group of women in Croydon who met regularly and called themselves the Fur, Fin and Feather Folk and who took a pledge " to refrain from wearing the feathers of any birds not killed for the purpose of food, the Ostrich only exempted.

" The organization did not allow men as members initially, avenging a policy of the British Ornithologists ' Union to keep out women.

Unlike the RSPB, which was primarily conservation oriented, the British Trust for Ornithology ( BTO ) was started in 1933 with the aim of advancing ornithological research.

Members were often involved in collaborative ornithological projects.

These projects have resulted in atlases which detail the distribution of bird species across Britain.

In the United States, the Breeding Bird Surveys, conducted by the US Geological Survey have also produced atlases with information on breeding densities and changes in the density and distribution over time.

Other volunteer collaborative ornithology projects were subsequently established in other parts of the world.
