XXI International Ornithological Congress; Vienna, Austria; August 21-27, 1994

自1884年以来，国际鸟类学大会定期举行。第21届奥林匹克委员会将于1994年8月在奥地利维也纳举行。这将是自铁幕倒塌以来召开的第一次大会，因此它为来自东西方集团国家的科学家广泛参与提供了第二次世界大战结束以来的第一次重大机会。许多国际合作项目预计将在大会上启动，预计出席会议的科学家和学生将超过2000人。美国科学家将广泛参加专题讨论会、研讨会等。专题讨论会分为五个主题领域：鸟类系统学、进化和生物地理学；生理学和营养生物学；行为、迁移和定向；生态、繁殖和人口结构；和保护。来自美国国家科学基金会的资金与来自美国鸟类学家联盟的旅行补助资金相匹配。

International Ornithological Congresses have been held at regular intervals since 1884. The XXIst IOC will be held in Vienna, Austria, in August, 1994. It will be the first congress to be held since the fall of the Iron Curtain, and it thus provides the first major opportunity since the end of World War II for extensive participation by scientists from both eastern and western bloc countries. Many cooperative, international projects are expected to be initiated at the congress, where the expected attendance may exceed 2,000 scientists and students. Participation by U.S. scientists in symposia, workshops, and so forth will be extensive. Symposia fall into five general thematic areas: systematics, evolution, and biogeography of birds; physiology and nutritional biology; behavior, migration, and orientation; ecology, reproduction, and population structure; and conservation. Funds from NSF are matched by funds from the American Ornithologists' Union for travel grants.
