Description: The blue-bellied roller (Coracias cyanogaster) is a bird belonging to the roller family. The blue-bellied roller is a sizable bird, approaching the dimensions of a jackdaw, measuring between 28 to 30 cm (11 to 12 inches) in length. It exhibits a dark brown back, with the head, neck, and breast covered in a buffy or chalky white plumage, while the rest of its feathers are predominantly blue. Adult blue-bellied rollers possess tail streamers measuring approximately 6 cm (2.4 inches).

Both sexes resemble each other, though juveniles have a less vibrant appearance compared to adults.

The blue-bellied roller was scientifically classified as Coracias cyanogaster in 1816 by the French naturalist Georges Cuvier. This classification was based on the work of François Levaillant, who described and illustrated “Le Rollier à ventre bleu” in 1806.

It is known to breed across Africa within a relatively narrow geographical band stretching from Senegal to the northeastern regions of the Democratic Republic of the Congo. These birds are typically residents, although there are occasional local seasonal movements, and they tend to inhabit mature, moisture-rich savannahs dominated by Isoberlinia trees.

Distribution and Habitat: Blue-bellied rollers are commonly found in warm, open landscapes with some tree cover. They often perch conspicuously on trees, posts, or overhead wires, reminiscent of giant shrikes, while scanning for grasshoppers and other substantial insects that make up their diet.

Nesting Behavior: Female blue-bellied rollers exhibit a nesting preference for tree holes, with a notable affinity for hollow palm trees as nesting sites. Within these secluded nooks, they carefully lay clutches of 2 to 3 eggs. Observations suggest that both male and female rollers participate in incubating the eggs, although it appears that females invest more time tending to the nest compared to their male counterparts.

These birds are notable for their powerful, direct flight, characterized by the striking contrast between their brilliant blue wings, dark back, cream-colored head, and trailing tail streamers. Their call is a distinctive harsh clicking sound, often described as “ga-ga-ga.”
