Abstract

Threatened birds of the Americas (1992) detailed 327 species, of which only four had ranges entirely outside the Neotropics, showing how important this latter region is for global bird conservation, contributing 30% of all threatened birds on earth. Brazil had 97 threatened species, Peru 64, and Colombia 56. These countries, plus Mexico, held three-quarters of all threatened birds in the Americas. Over 78% (256) of all threatened bird species possessed ranges of less than 50,000 km². Some 57% of all threatened birds were confined to wet forest, 17% to dry forest, and 10% to grasslands, a rapidly disappearing habitat type. Over 76% suffered from loss of habitat (for 49% this is the only threat); 16% and 11% suffered significantly from hunting and trade respectively, and 8% were threatened as a function of their restricted ranges. Roughly 30% (twice as many as in Africa) were Endangered (highest category), another 30% divided equally between Indeterminate and Vulnerable, 30% were Rare, and 10% were Insufficiently Known (lowest). Of 146 species in the two highest categories, only nine were under sufficient management regimes, 23 might already have become extinct, 16 needed immediate intervention, and 42 needed very urgent attention. Parrots (28% of New World species threatened) and cracids (26%) suffered disproportionately through the combination of habitat loss and intensive human exploitation (trade and hunting respectively). A key means of saving threatened species lies in the identification and protection of areas in which they are sympatric.

Journal Information

The Ornithological Monographs series, published by UC Press for the American Ornithologists' Union (AOU), has been established for major papers and presentations too long for inclusion in the Union's journal, The Auk. The series has been published since 1964 and has featured over 60 monographs on a range of ornithology subjects.

Publisher Information

The American Ornithological Society was created in 2016 as a merger between the American Ornithologists' Union (AOU), founded in 1883 and the oldest organization in the New World devoted to the scientific study of birds, and the Cooper Ornithological Society (COS), founded in 1893. The mission of the AOS is to advance the scientific understanding of birds and disseminate ornithological knowledge, to enrich ornithology as a profession and mentor young professionals, and to promote a rigorous scientific basis for the conservation of birds. The AOS publishes two of the foremost ornithological journals in the world: The Auk: Ornithological Advances and The Condor: Ornithological Applications; the Checklist of North and Middle American Birds and the complementary Checklist of South American Birds; the award-winning Series in Avian Biology book series and the Ornithological Monograph series; and co-sponsors Birds of North America (published online through the Cornell Lab of Ornithology).

Which cause results in the most extinctions?

Habitat loss remains the main driver of extinctions, but it may act synergistically with other drivers such as over harvesting and pollution, and, in the future, climate change.

Which are human causes of extinction quizlet?

Most of the main causes of extinction are caused directly or indirectly by humans. Humans negatively impact the environment for controlling and artificially causing fires, shifting agriculture cultivation with unsustainable techniques, grazing by domesticated animals, overkilling species (Pleistocene overkill), etc.

Which factors involving the activities of people are threat to biodiversity?

The human population requires resources to survive and grow, and many of those resources are being removed unsustainably from the environment. The five main threats to biodiversity are habitat loss, pollution, overexploitation, invasive species, and climate change.

Which factors involving the activities of people are a threat to biodiversity quizlet?

Habitat destruction, climate change, invasive species, pollution, the human population growth, and overharvesting are the greatest threats of biodiversity.
