During my tours as a birding guide in the vast, arid landscapes of North Africa, I always see bird watchers get confused between two amazing ground-dwelling birds: the Crowned Sandgrouse (Pterocles coronatus) and the Spotted Sandgrouse (Pterocles senegallus). Because the color of their plumage makes them go incognito and align perfectly with the earthy terrain, many find it hard to tell them apart from far away. But they are actually very different animals with unique characteristics.
This article will look at their appearance, their wings in flight, and how they live so you can identify them easily next time you are on a desert expedition.
Physical Appearance and Colors
Let us start with the most obvious difference when you look at them on the ground.
- Crowned Sandgrouse: The adult male has a very striking and serious black mask on his face, and he lacks any grey tones on his neck and breast. The females do not have this black mask. Instead, the females have dark, wavy lines (called vermiculations) that cover their entire belly.
- Spotted Sandgrouse: The male looks very different in the face. He has no black mask but features a beautiful orange throat, a pale grey collar, and a reddish-brown nape. The female is generally duller but is liberally covered in dark spots, which is the exact reason of why it is called the “Spotted” Sandgrouse.
Wings and Flight Style
Their wings are built with small details that help us know who is who when they fly to waterholes.
- Crowned Sandgrouse: When they take to the sky, you will see wholly dark flight feathers. This completely dark trailing edge on the wings is the absolute best feature to identify the Crowned Sandgrouse from a distance.
- Spotted Sandgrouse: Their flight feathers are much paler with only dark trailing edges, not completely dark. Furthermore, if you look closely at their shape in the air, the Spotted Sandgrouse has elongated central tail feathers and a very distinct dark stripe on its belly.
The Sound Of The Sandgrouse
When I was with a group of ornithologists waiting at a waterhole at dawn, we often heard these birds before seeing them.
- Crowned Sandgrouse: Their sounds are generally softer and more subtle chattering when they are in their flocks.
- Spotted Sandgrouse: This bird is known for a very musical and distinct call that sounds like “queeto-queeto.” They use this melodious sound as a communication tool within the flock and as an alarm to warn others of predators like falcons.
Nesting Habits On The Earth
Where do they put their eggs? Both are solitary nesters that put their eggs on the earth directly, but there is a small difference.
- Crowned Sandgrouse: They prefer stony deserts and dark red sandstone areas. When the female makes a shallow depression for her nest, she often moves small stones to the rim to create a protective circle around the eggs.
- Spotted Sandgrouse: They choose flat, open stony plains. They just find a simple depression in the dirt or sand to lay their camouflaged eggs without building a stone ring.
The Sandgrouse Known For:
Both of these amazing birds belong to the Pteroclidae family, which is known for a very unique adaptation. Because they live in extreme heat where water is scarce, the male sandgrouse has a special superpower. His belly feathers act like a sponge to absorb and hold water when he visits a drinking hole. He then flies long distances to carry this water back to the chicks, who drink the water directly from his wet plumage. This method is unique among all birds!
| Feature | Crowned Sandgrouse | Spotted Sandgrouse |
| Male Face | Striking black mask | Orange throat, pale grey collar |
| Flight Feathers | Wholly dark | Pale with dark edges |
| Tail Shape | Standard short tail | Elongated central tail feathers |
| Belly in Flight | Light / uniform | Distinct dark stripe |
| Call | Soft chattering | Musical “queeto-queeto” |
Conclusion and Conservation
Both birds are masters of survival in the desert in their own way. As we know, deserts are harsh environments, and these birds rely heavily on the few scattered waterholes that exist. Climate change and unregulated hunting can easily affect their continuity. We must collaborate to preserve their habitats so they don’t disappear.
I encourage you to bring your binoculars and wake up early next time you visit the desert to see if you can spot the difference between the black mask of the Crowned and the spotted belly of the Spotted Sandgrouse. It is very fun to watch them fly!
