Discovering the African Harrier - Hawk
As a bird enthusiast and nature guide, I've been fortunate to observe and study numerous fascinating avian species. Today, I'd like to take you on a journey through the world of a truly remarkable bird – the African Harrier - Hawk, also known as the Gymnogene (Polyboroides typus).
This medium - sized raptor, measuring around 60 – 66 cm in length, is a master of adaptation and a spectacle of natural beauty and agility.
A Glimpse of Grace and Strength
The African Harrier - Hawk is an exquisite bird with a captivating appearance. Its upperparts, head, and breast boast a pale grey hue, while the belly is adorned with fine dark barring against a white background.
The broad wings are similarly pale grey, edged with black and lined with a narrow white stripe. The tail presents a striking contrast with its black color and a broad white band.
Perhaps the most distinctive feature is the bare facial patch, which varies in color from red to yellow and also gives origin to the name in Afrikaans: "Kaalwangvalk".
Double - Jointed Ankles
One of the most intriguing aspects of the African Harrier - Hawk is its double - jointed ankles, a trait it shares with the Neotropical Crane Hawk and the extinct Australian Pengana.
This remarkable adaptation allows the Harrier - Hawk to delve into otherwise unreachable holes and crevices in search of prey, demonstrating a fascinating example of convergent evolution.
A Versatile Raptor
The African Harrier - Hawk is predominantly found in Africa south of the Sahara, thriving in a variety of habitats. From the thick rainforests of the Dzanga - Sangha Special Reserve in the Central African Republic to the agricultural lands and urban areas, this bird exhibits remarkable adaptability.
Its presence in human - occupied regions, including traditional rural villages in eastern Guinea - Bissau and even in palm trees within cities, underscores its versatile nature.
A Dance in the Sky
The breeding season of the African Harrier - Hawk varies geographically. In Nigeria, it spans from March to August, while in southern regions, it aligns with the austral summer.
These birds are known for their elaborate courtship displays, where they soar together at great heights, often calling out in unison.
The male's undulating flight and the mutual talon - touching mid - air are sights to behold, reflecting the depth of their bonding rituals.
Diet and Foraging
This species is omnivorous, feeding on both plant and animal matter. Its diet includes fruits like oil palm and small vertebrates.
The African Harrier - Hawk's climbing ability and unique leg structure enable it to raid nests for eggs and nestlings, and even prey on introduced species like Feral Pigeons and House Sparrows.
It employs various hunting strategies, including low and high soaring, perch hunting, and ground foraging, showcasing its versatility as a predator.
Physical Characteristics and Lifespan
The African Harrier - Hawk is notable for its grey plumage, with a face featuring orange and yellow colors and vibrant yellow, short legs.
Females tend to be slightly larger than males. These monogamous birds are known to mate for life, and their lifespan can exceed ten years in the wild, blending the longevity traits of both Harriers and Hawks.
Conservation Status
Currently classified as "Least Concern," the African Harrier - Hawk has a stable population, although it faces challenges like deforestation and human encroachment.
However, its adaptability and resilience have allowed it to thrive in various environments.
Conclusion
The African Harrier - Hawk, or Gymnogene, stands as a testament to the wonders of avian evolution and adaptation. Its unique features, ranging from double - jointed ankles to complex courtship displays, make it a fascinating subject for bird enthusiasts and nature lovers alike.
As we continue to explore and understand these magnificent creatures, they remind us of the intricate and beautiful tapestry of life that exists in our natural world.
