Home›Birds›Population Trend›DecreasingBrowse ByDecreasingPopulation 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.FactsDecreasingSourcesComments (0)Reader Challenges (0)FactsComparisonReproductive ModeWell-attestedOviparous (Egg-Laying) 1DecreasingFilter Results2 entriesCommon GroupAllBirds Of Prey (Raptors) (1)Passerines (Songbirds) (1)Everyday GroupAllBirds Of Prey (Raptors) (1)Passerines (Songbirds) (1)HabitatAllLake (1)River (1)Tropical Rainforest (1)Where It LivesAllAfghanistan (1)Albania (1)Andorra (1)Argentina (1)Armenia (1)Austria (1)Azerbaijan (1)Bangladesh (1)Belarus (1)Belgium (1)Bhutan (1)Bolivia (1)Bosnia and Herzegovina (1)Brunei (1)Bulgaria (1)Canada (1)Chile (1)China (1)Colombia (1)Cyprus (1)Denmark (1)Ecuador (1)Germany (1)North America (1)Norway (1)South Asia (1)Switzerland (1)United Arab Emirates (1)Conservation StatusAllCritically Endangered (1)Least Concern (1)DietAllCarnivore (1)Insectivore (1)System (Realm)AllFreshwater (1)Terrestrial (1)Living or ExtinctAllYes (2)Relationship to PeopleAllHunted or Fished (1)Natural Pest Control (1)CITES AppendixAllAppendix I (1)Not Listed (1)NatureServe RankAllG5 Secure (1)TaxonomyAllAccipitridae (1)Hirundinidae (1)Show ResultsBrowseCompareSelect all 2Philippine EagleDecreasingSand martinDecreasingSources1.
