Home›Birds›Population Trend›StableBrowse ByStablePopulation trend shows whether a species overall numbers are believed to be increasing, decreasing or stable, or whether the trend is simply not known. This is a separate measure from conservation status: a species can be common today and still be declining, or rare and holding steady. The trend recorded here follows the most recent assessment cited on that species own page.FactsStableSourcesComments (0)Reader Challenges (0)FactsComparisonReproductive ModeWell-attestedOviparous (Egg-Laying) 1StableFilter Results3 entriesCommon GroupAllPenguins And Seabirds (1)Shorebirds (Waders) (1)Waterfowl (1)Everyday GroupAllPenguins And Seabirds (1)Shorebirds (Waders) (1)Waterfowl (1)HabitatAllEstuary (1)Marine (1)Wetlands (2)Where It LivesAllAfrica (1)Argentina (2)Armenia (1)Australasia (1)Australia (3)Barbados (1)Belgium (1)Bhutan (1)Brazil (2)Canada (1)Colombia (1)Denmark (1)Djibouti (1)Ecuador (1)El Salvador (1)France (1)Mauritius (1)Nepal (1)Netherlands (1)New Zealand (2)Nigeria (1)North America (1)Norway (3)Poland (1)Russia (1)Senegal (1)South Africa (1)South America (1)South Asia (1)Spain (1)Sweden (1)Ukraine (1)United Kingdom (1)United States (1)Uruguay (1)Zambia (1)Conservation StatusAllLeast Concern (3)DietAllInsectivore (1)Omnivore (1)Piscivore (1)System (Realm)AllFreshwater (2)Marine (3)Terrestrial (3)Living or ExtinctAllYes (3)ThreatsAllPollution (1)Relationship to PeopleAllHunted or Fished (1)Invasive or Introduced Species (1)CITES AppendixAllNot Listed (3)NatureServe RankAllG5 Secure (1)EcosystemAllAntarctic Peninsula (1)Prairie Pothole Region (1)TaxonomyAllAnseriformes (1)Charadriiformes (1)Sphenisciformes (1)Show ResultsBrowseCompareSelect all 3King PenguinStableMallardStablePied StiltStableSources1.
