Identification

Field

Identification:

The African Scops-Owl measures up to 20cm and weighs around 80g. They are known for their camouflaging coloration, which serves as excellent protection against predators.

Even though they are small, they have a bulky Mediterranean-hawk-like body, a round head, a small bill. Their most striking feature is their piercing eyes, which are bright yellow and stand out from the feathers around their face.

Their facial disc is a pale gray-brown color, with a black rim around the eyes. Their feathers are mainly rust-brown orange with buff and gray-brown coloration.

Similar Species:

When it comes to identifying the African Scops-Owl, it’s important to be aware of similar species. Some of the owls that might be mistaken for the African Scops-Owl are the Eurasian Scops-Owl, the Desert Owl, and the Pallid Scops-Owl.

However, one of the most important distinguishing features is their geography – the African Scops-Owl can only be found in sub-Saharan Africa.

Plumages

The African Scops-Owl is often referred to as a “little bird with big attitudes.” This holds true when it comes to their plumages, too. While they do not have extravagant plumages, their feathers are unique in their own ways.

Adult African Scops-Owls have a reddish-brown coloration, with lighter feathers on their bellies and underwings. Juvenile African Scops-Owls, on the other hand, are much greyer in color.

The feathers around their face are striking – the black rims around their piercing yellow eyes create a fierce and captivating look.

Molts

Like many birds, African Scops-Owls molt their feathers. There are two molting periods for the African Scops-Owl: the pre-breeding molt and the post-breeding molt.

The pre-breeding molt occurs between December and February, and involves the replacement of feathers that have become damaged or worn. The post-breeding molt takes place between August and October, during which the birds replace all their feathers.

The molting period can be a vulnerable time for birds, and the African Scops-Owl is no exception. During this period, they may have difficulty flying and hunting.

Birdwatchers and conservationists alike should be mindful of avoiding disturbances during this time.
