10 Fascinating Facts about the Blue-spotted Wood-Dove

The Blue-spotted Wood-Dove, also known as Turtur afer, is a beautiful bird that can be found in the forests and savannas of sub-Saharan Africa. In this article, we will explore the identification of this species, including its physical characteristics, how to differentiate it from other similar species, its plumages, molts, and other interesting facts that make the Blue-spotted Wood-Dove a unique bird.

Identification

The Blue-spotted Wood-Dove is a medium-sized bird, measuring about 20 centimeters in length, and weighing around 100 grams. Its body is predominantly brown, with a bluish-grey head, a pinkish-brown breast, and a greenish back.

The bird has a distinctive blue patch on its neck that gives it its name. Its wings are short and round, and its tail is slightly rounded.

Field

Identification

When observing the Blue-spotted Wood-Dove, it shows a distinctive slow and deep wingbeats and a characteristic hovering flight with dangling legs. The bird is quite shy and tends to hide in thick vegetation, making it challenging to spot.

One can listen for its call, which is a soft and rhythmic “too-too-too,” sounding like someone tapping a stick on a hollow log. The call is usually heard around sunrise and sunset and may last for several minutes.

Similar Species

It is easy to confuse the Blue-spotted Wood-Dove with other species in the same genus, such as the Tambourine Dove and the Black-billed Wood-Dove. The Tambourine Dove is slightly smaller than the Blue-spotted Wood-Dove, lacks the blue patch on its neck, and has a yellow eye-ring.

The Black-billed Wood-Dove, on the other hand, has a black bill, unlike the reddish-brown bill of the Blue-spotted Wood-Dove.

Plumages

Most Dove species have only two molts per year, which means that their feathers change twice: once during the breeding season and again during the non-breeding season. However, the Blue-spotted Wood-Dove displays three distinct plumages in the course of a year.

Adult birds have three plumages: the breeding, non-breeding, and immature. The breeding plumage of the Blue-spotted Wood-Dove is characterized by a more vibrant and glossy appearance, with brighter colors on the head and neck, and fewer scales on the breast.

The non-breeding plumage is less distinct, with duller colors and more scales visible. Immature birds are similar to adults but have a more muted appearance and fewer blue spots on their necks.

Molts

The Blue-spotted Wood-Dove will have multiple molts throughout their lives. The first important molt occurs when the bird is just six to eight weeks old, and it replaces its original downy feathers with juvenile feathers.

The next major molts occur during the first year of life, when the bird will change their juvenile feathers for new ones twice: once during the breeding season and again during the non-breeding season. As the bird matures, molting slows down to become an annual event.

Adult birds molting typically occurs in late summer to early autumn, after the breeding season. During this time, birds will replace their old feathers with new ones slowly, over several months.

Conclusion

In summary, the Blue-spotted Wood-Dove or Turtur afer is a medium-sized bird with unique physical characteristics. Its distinctive blue patch on its neck sets it apart from other Dove species, and its hovering flight with dangling legs is a sight to see.

With its three plumages and various molts throughout its life, this bird is truly a marvel to observe and appreciate. It is always a joy to learn about the Blue-spotted Wood-Dove and the fascinating world of birds.
