The Silvery-Cheeked Hornbill: A Giant of Tanzania’s Forests

Introduction

The silvery-cheeked hornbill is a spectacular bird of East African forests and wooded landscapes. Its large size, pale cheek feathers and prominent bill make it an impressive sight, while its loud calls can carry through the trees.

For visitors exploring Tanzania’s forested habitats, this hornbill offers a very different birdwatching experience from the species found in open grassland.

How to Identify It

The silvery-cheeked hornbill is a large, dark bird with silvery-white feathers around the head and neck. Its bill is long and curved, with a prominent casque on top.

In flight, its broad wings and substantial body make it easy to distinguish from smaller forest birds.

What Does It Eat?

Its diet includes fruit and a range of animal prey, depending on availability. By feeding on fruit and moving between trees, hornbills can help disperse seeds across forest habitats.

They may also take insects and other small animals, making them important participants in the forest food web.

Where Can You See It in Tanzania?

Silvery-cheeked hornbills occur in suitable forest and woodland habitats in Tanzania, including parts of the northern region. Forested areas around Mount Meru and other wooded landscapes may offer opportunities, depending on the precise location and season.

They are often easier to hear than to see, so listen for their calls and watch the canopy.

Why Forest Conservation Matters

Large forest birds depend on healthy tree cover and suitable nesting sites. Forest degradation and the loss of mature trees can affect the habitats that hornbills need for feeding and breeding.

Protecting forest ecosystems also supports monkeys, other birds, insects and countless plant species.

Size and Sounds

The silvery-cheeked hornbill (Bycanistes brevis) is around 75 to 80 centimetres long. Males have a large pale casque on top of the bill, while females have a smaller casque.

Its loud, braying call carries a long way through the forest. In flight, its wings make a heavy whooshing sound that you can often hear before the bird appears above the canopy.

A Remarkable Way of Nesting

Like many hornbills, the female seals herself inside a tree cavity before laying eggs. She closes the entrance with mud, droppings and food remains, leaving only a narrow slit.

The male feeds her and later the chicks through this opening, delivering fruit and other food many times a day. This protects the nest from predators but makes the family completely dependent on the male and on large trees with suitable holes.
