Discovering the Spotted Eagle - Owl
Nature has some remarkable creatures, and among these enigmatic wonders is the Spotted Eagle-Owl (Bubo africanus). This medium-sized owl, known for its striking appearance and adaptable nature, captivates all who encounter it. As a nature enthusiast, let's delve into the captivating world of the African Spotted Eagle-Owl.
The Owl of Many Names
The Spotted Eagle-Owl, also known as the African Eagle-Owl, is one of the smallest species within the eagle owl family. With a wingspan ranging from 100 to 140 cm and a length of 45 cm, it may not be the largest owl species, but it certainly leaves a lasting impression.
These majestic birds sport off-white to pale ochre facial disks that beautifully frame their striking yellow eyes. Their prominent ear-tufts add to their charm, making them easily distinguishable.
A Separate Species
Until 1999, the Spotted Eagle-Owl was considered conspecific with the Greyish Eagle-Owl, a close relative. However, it was later recognized as a separate species, highlighting its uniqueness in the avian world.
There is another Eagle-Owl inhabiting Southern Africa that can often be confused with the Spotted Eagle-Owl, the Cape Eagle-Owl, its orange eyes and slightly darker plumage is the difference noticeable. Its distribution is not as common though, they reside more south into South Africa.
Urban Dwellers
One of the remarkable aspects of the Spotted Eagle-Owl's lifestyle is its ability to coexist with humans. Often referred to as "urban owls," they reside in close proximity to human habitation, making them a common sight in Southern Africa.
Their adaptability allows them to thrive in various environments, from thorn savannas to suburban gardens, such as on the outskirts of Harare, Zimbabwe.
A Varied Diet
Spotted Eagle-Owls have a diverse diet, feeding on rodents, small mammals, birds, insects, and reptiles but their dietary preference however, leans towards small mammals like rodents and shrews.
They exhibit a unique feeding behavior, often swallowing their prey whole, with occasional pauses, head-jerking, and resting in between. Any indigestible parts, such as feathers and bones, are regurgitated in the form of pellets within the next 24 hours.
Nomads of the Night
Unlike some owl species that remain sedentary, the Spotted Eagle-Owl is more of a wanderer, moving from one hunting territory to another every few weeks or months. These itinerant creatures return periodically, depending on local prey availability.
This allows the population of food resources to thrive and regenerate, allowing the ecosystem to reach stability again, until the return of the owls once there is sufficient food again that also needs to be controlled by the nomads of the night.
Vocal Acrobats
Spotted Eagle-Owls are known for their melodious hoots. The male typically calls with two hoots, "Hooo hooopoooo", and the female responds with three "Hooo hoo hooo”.
Their vocalizations are very interesting, as they age they learned it all, from hissing and snapping their beaks to threaten danger away, to soft croaking when in a comfortable social setting. These fascinating sounds are a testament to their complex social interactions and communication.
Breeding Ways and Monogamous Ways
Spotted Eagle-Owls are monogamous, yet they will find a new mate swiftly if their partner passes away. Breeding typically occurs from late July to early February, with the female laying 2 - 4 eggs.
During this time, the female is dedicated to incubation, while the male provides food. After an incubation period of around 32 days, owlets emerge. At about five weeks of age, these owlets leave the nest, spending about ten days on the ground, honing their hunting skills and learning how to fly and survive.
Parents continue to support and feed the young ones, offering larger prey items such as rodents. Their rasping cries for food can be heard over great distances, ensuring that parents are aware of their location. This can be problematic as it also lures attention from potential danger.
Challenges and Conservation
While the Spotted Eagle-Owl is not globally threatened, they face numerous challenges. Car collisions, electric wires, persecution, secondary poisoning, and parasite infections are among the leading causes of mortality. Juveniles and fledglings are particularly vulnerable.
It's crucial for us to recognize these threats and take measures to protect these remarkable creatures. Their numbers are doing well even though their struggles with human intervention, perhaps a testament that they are breeding at a high success rate.
You will often drive along the roads and find owl road signs, this is a small step but yet so relevant, it gets seen by many road users and alerts them especially at night. Even people putting up owl boxes, giving these birds a safe place to then breed and raise their young.
In Conclusion
The Spotted Eagle-Owl is a testament to nature's adaptability and resilience. Their remarkable behaviors, vocalizations, and stunning appearances make them an essential part of the ecosystems they inhabit.
As nature enthusiasts, let us cherish and protect these incredible birds, ensuring they continue to grace the night skies and bring enchantment to our world.
