The shoebill (Balaeniceps rex) looks like a bird that belongs in the prehistoric age. Found in the marshes of East Africa, the shoebill is classified as vulnerable and is a bucket-list sighting for any avid birder.
Here are seven reasons to love this big bird:
1. They may be big, but they can fly if they want to. Granted, shoebills don’t fly very far, and long flights are rare, but flying is no mean feat considering they can grow up to 1.5m tall and can weigh up to 7kg!
2. Shoebills eat fish that look almost as prehistoric as they do! Although shoebills have been known to gulp down other birds, baby crocodiles, frogs, terrapins, water snakes and even small mammals, the lungfish is their staple diet.
3. Their distinguishing feature is the enormous shoe-shaped bill, measuring an incredible 23 centimetres in length and 10 centimetres in width, with a razor-sharp, curved hook at the end. Shoebills use their bills to strike their prey, known as a “collapse”, and its the antitheses of its patient stalking technique. Like a geological fault accumulating kinetic energy, this blue monolith will bolt downwards when triggered loose by the rippling of an incoming fish. Head first, gape open, and wings spread, it smashes through the vegetation in the hopes of coming up with a fish. Then, whilst keeping its head aloft from the water, it will slide its bill sideways so as to severe its prey, while the water and vegetation snatched up in the strike spills out from the edges of the bill.
4. Their large bill comes in very handy to carry large ‘gulps’ of fresh water back to the nest in order to douse eggs or chicks when the sweltering heat of the swamps drives temperatures beyond normality. Other fascinating techniques to cool down involve defecating on their legs (as storks do too), or gular fluttering – the same as dog panting.
5. Shoebills have specially adapted long toes with no webbing which helps them to balance on the swampy vegetation while stalking prey. They also have a nictitating membrane – a translucent layer that protects their eyes – which is used when hunting and preening.
6. Shoebills have a little bit of an identity crisis. While they may look stork-like, taxonomically speaking they share more traits with the Pelecaniformes (herons and pelicans), and molecular studies have found the hamerkop to be the closest relative of the shoebill.
7. Shoebills will usually have two chicks, but only the one who proves to be the strongest survives – the other is left to die. While attending the nest, adults perform bill-clattering displays, accompanied sometimes by a whiney-mewing muttering that often elicits a ‘hiccupping’ gurgle from their chicks as they beg in anticipation for food. Both the chicks and the adults engage in bill-clattering during the nesting season as a means of communication.
