Coastal Raptors
In Argentina, the maritime coasts encompass an extensive area (about 4,000 kilometers), presenting a great diversity of birds. Numerous studies have been conducted focusing on seabirds. Research on these birds began in the 1970s, but it wasn't until the 1990s that the number of contributions substantially increased.
Regarding diurnal birds of prey, due to their geographical distribution, around 13-14 species could be utilizing the Patagonian maritime coasts for breeding. However, prior to the studies carried out within the framework of the "Northeast Patagonian Birds of Prey Project," existing information about raptors on the sea coasts was scarce and mostly anecdotal.
Since our first publication in 2012 until the present date, we have provided information about 11 of these species namely:
Order Falconiformes. Family Falconidae.
Peregrine Falcon (Falco peregrinus)
2. Aplomado Falcon (Falco femoralis)
3. American Kestrel (Falco sparverius)
4. Southern Caracara (Caracara plancus)
5. Chimango (Milvago chimango)
Order Accipitriformes. Family Accipitridae.
6. Variable Hawk (Geranoaetus polyosoma)
7. Black-chested Buzzard-Eagle (Geranoaetus melanoleucus)
8. Cinereous Harrier (Circus cinereus)
9. Long-winged Harrier (Circus buffoni)
Order Cathartiformes. Family Cathartidae.
10. Black Vulture (Coragyps atratus)
11. Turkey Vulture (Cathartes aura)
*Contributions about these three species were not made on the sea coasts but in areas of influence.
