How to recognise it
The Shoebill is a striking, large, wading bird with a distinctive shoe-shaped bill. Its plumage is predominantly blue-grey, with a slightly darker back and wings. The massive bill is greyish in colour and can reach up to 24 cm in length.
Both sexes look similar, with males being larger and have longer bills. There are no significant seasonal changes in plumage. Juveniles have a smaller bill and duller colouration compared to adults, gradually developing adult features over several years.

Its song and calls
Shoebills are generally silent birds, but they produce a distinctive bill-clattering sound during courtship or when threatened. This rapid clattering, described as a 'machine-gun-like' tak-tak-tak, can be heard from a considerable distance. They may also emit low, cow-like moo-ing sounds.
When and where to see it

Tips for seeing it
- Look for Shoebills in large, tropical swamps and marshes
- Be patient, as they often stand still for long periods
- Listen for their distinctive bill-clattering sound
- Observe from a distance to avoid disturbing these shy birds
- Visit protected areas in East Africa for the best chances of sighting
What it eats
Shoebills primarily feed on fish, especially lungfish and catfish, but also consume frogs, snakes, and occasionally small crocodiles.
They hunt using a unique technique called 'collapsing', where they suddenly lunge forward to catch prey with their powerful bill.
Nesting and breeding
Shoebills form monogamous pairs and breed during the dry season when water levels are lower. They construct large, flat nests of reeds and grasses on floating vegetation or solid ground in swamps.
Females typically lay 1-3 white eggs, which both parents incubate for about 30 days. The eggs often become stained brown from the nest materials.
Chicks hatch asynchronously and are cared for by both parents. They fledge after about 3-4 months but may remain dependent on their parents for up to a year.
Behaviour
Shoebills are known for their statue-like stillness when hunting, often standing motionless for long periods. They are generally solitary birds, rarely seen in groups.
They exhibit a slow, deliberate gait when moving, and their flight is powerful but infrequent.
Conservation
The Shoebill is classified as Vulnerable due to habitat loss, hunting, and capture for the wild bird trade.
Conservation efforts focus on protecting wetland habitats and reducing human disturbance. Monitoring programs and international cooperation are crucial for the species' survival.
