Part II of this nocturnal series sees us focus on a family of birds that I truly find fascinating; the owls. They have a presence, unlike any other bird, striking pure and genuine excitement when one is seen. Taking even the briefest moment to appreciate these amazing specialists of the night is always worthwhile.
At Londolozi, we have the honour of seeing many different species of owls. In fact, out of all the twelve species of owls that occur in Southern Africa, only the Cape Eagle Owl has not been recorded at Londolozi. That is an incredible record, and yes, there was a record of a Pel’s Fishing Owl here many years ago.
Owls are synonymous with nocturnal activity and have developed many adaptations to help them be so successful. The Pearl Spotted Owlet and the Barred Owlet are two of the smaller birds in the owl family that are, in fact, not nocturnal. They are voracious daytime predators of other small birds.
So what makes owls so successful in their niche of being nocturnal aerial predators? Well, it cannot be pinpointed to one factor or character but rather to many different aspects in combination.
Silent flight
Owls have specialised flight feathers that allow them to swoop towards their prey in complete silence. These feathers alter the air currents that flow over the wings, resulting in a remarkable reduction in noise as the upper and lower currents merge at the wing’s specialised trailing edges.
Incredible hearing
Owls have acute hearing. Their ear cavities are offset, this allows a split-second difference in the reception of sound in each ear. This unique way of hearing allows them to pinpoint sounds made by potential prey, a key feature when hunting in complete darkness. An owl’s hearing is so advanced, that they can almost exclusively hunt just by sound.
Night vision
Owls’ eyes are incredibly special. Their eyes are conical and set deep within their sockets. These cone-like eyes that are fixed in the socket mean that although they have binocular vision, the owl must physically turn its head in order to see things around it. Being able to turn their head 270 degrees helps them in this aspect. They are unable to move their eyes independently of the head.
The cornea and pupil of an owl are significantly larger than ours. Meaning that their rod cells heavily outweigh the number of cone cells. Because of this, they have monochrome vision but can make use of the smallest amount of light in the darkest of evenings.
Owls are remarkable birds that are the masters of the night. They have all the tools to continue to dominate the in darkness. Next time you see an owl, remember the unique features they possess in order to continue thriving in difficult conditions.
Patrick I love the owls as well. The Southern white faced owl is beautiful. The Spotted eagle owl had a box in my tree in my yard that my husband made for them. They raised 3 chick’s in that box and the parents were quite tame. They used to sit in the tree and the female used to come and sit on the grape vine by our lappa door, in day time and just sit there with her eyes closed. Sometime they used to fly on the grass and sit near the pond looking for any frog or lizard. At dawn she used to call the chick’s to come out of the box and fly over the wall to the open field. Next morning all 5 would be back in the tree. We have since moved and now live I a reserve with antelope, giraffe,zebra,kudus and bush pigs, and many other animals. I have heard the Spotted eagle owl here but not seen the second one yet. The first one was here in my yard and sat on the wooden fence and went through to my neighbor for a drink of water. Later on I heard that owl had flown in a pole and hurt itself.
Thanks for the part II on the Nocturnal species in Londolozi. As much as I’m fascinated by owls, I’ve only seen the Spotted Eagle Owl and both times in the dark of night, lit only by a spot – typical for this owl I suspect. One day perhaps, I will see the little Pearl Spotted Owlet.
Owl’s are fascinating birds. Thank you for sharing your insight and the beautiful pictures of the many owls of Londolozi.
amazing owl finds “who” doesn’t love owls. I hope I get to see some!
Hi Patrick, do you have Scops Owls in Londolozi? They usually migrate from Africa to Europe in summer, they spend the season here, but I haven’t heard them this year. At night you can hear their distinguished call. They are the smallest owl species. Thank you for this beautiful pictures and Blog
Fabulous! Love the owls. Some of our favorite moments have been searching for owls at Londolozi
Thanks Patrick! We learned a lot! Can’t wait to find some Owls on our next visit!
