Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The Western Osprey faces critical threats from widespread habitat degradation, pollution of aquatic ecosystems, and climate change impacts on fish populations. Persistent organic pollutants like DDT continue to cause eggshell thinning and reproductive failure in many populations, while coastal development and dam construction destroy essential nesting and foraging areas.
Key Facts
Habitat & Distribution
Coastal waters, large rivers, lakes, and reservoirs with abundant fish populations, requiring tall structures or trees near water for nesting. Found in both freshwater and marine environments from sea level to moderate elevations, with preference for clear waters that allow visual hunting of fish prey.
