This is a list of Gaviiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology. All Gaviiformes have been quantified.
In total there are about 11,000 species of birds described as of 2024, [1] though one estimate of the real number places it at almost 20,000. [2] The order passerines (perching birds) alone accounts for well over 5,000 species.
Population Status Trend Notes Image Andean flamingo: Phoenicoparrus andinus: 38,000 [1] VU [1] [1] Maximum estimate. The population has been steadily decreasing, and current population is unknown. [1] James's flamingo: Phoenicoparrus jamesi: 106,000 [2] NT [2] [2] Estimated value from 2010 census. Actual population will likely be lower due to ...
Known scientifically as Ardea humbloti, the Madagascar heron was added to the red list in 2016 following a review of the population’s size at the time.A team assessed the species for inclusion ...
Estimate for mature individuals only. Broader range of population estimated at 800–1,600. The estimate to the left is the best available. Species needs further study due to severe declines in population in recent decades. [33] Lava gull: Larus fuliginosus: 900-1,200 [34] VU [34] [34] Equal to 600-800 mature individuals. May be an overestimate ...
