In this article, we will explore the identification, plumages, and molts of the black coucal, along with field identification and similar species, all of which will help birdwatchers spot these elusive birds.

Identification

The black coucal is a medium-sized bird, identifiable by its black plumage and a distinctive long tail. The bird has a greenish-blue sheen on its head and body, which is clearly visible during bright light conditions.

The size of males is larger than females, with the males measuring up to 45-50 cm and females measuring 40-45 cm. The bird’s beak is straight and pointed, with a reddish-brown color.

The legs of the black coucal are dark and strong, adapted for life in the dense undergrowth.

Field

Identification

When it comes to field identification of the black coucal, it is essential to take note of the birds habitat.

These birds live in dense undergrowth or swamp forests and can be heard more often than seen. Typically, their call is the best way to identify them.

The bird’s call is a low-frequency “whoomp,” which can be heard in the early mornings or late evenings. The bird’s call resonates throughout the forest, making it quite distinct.

In addition, their flights are short and fast, usually restricted to a few meters with a burst of wings and a drop.

Similar Species

While the black coucal is quite distinctive, there are a few species that one must be careful not to confuse them with. One such species is the African cuckoo, which is significantly larger and has white spots on its tail feathers.

Another species is the long-tailed cuckoo, which resembles the black coucal from afar, but has a much longer tail. The red-chested cuckoo is another species that birdwatchers must be careful not to confuse with the black coucal.

They have a predominately brown body with a prominent reddish-brown chest.

Plumages

The black coucal has three main plumages: juvenile, immature, and adult. The juvenile plumage has a dull brown color that helps the bird blend into the undergrowth.

The immature plumage is a dark brown color, with a blackish-grey sheen on the head and upperparts. In contrast, the adult plumage has a deep black color with a greenish-blue sheen on the upperparts.

Molts

The molting process is an essential part of the black coucals life cycle, allowing it to maintain its plumage in top condition. The bird goes through two molts in a year: the pre-breeding molt (occurring in December-February) and the post-breeding molt (occurring in July-August).

During the pre-breeding molt, the bird sheds its old feathers and starts growing new ones, which help them attract mates. In contrast, the post-breeding molt allows the bird to replace any damage to their feathers resulting from breeding or environmental factors.

In conclusion, the black coucal (Centropus grillii) is a fascinating bird species that is worth watching out for. With a proper understanding of its identification features, habitat, plumages, and molts, birdwatchers can spot these elusive birds with ease.
