From Romeo and Juliet to Liang Shanbo and Zhu Yingtai, couples in literature and mythology have given their everything – including their life – to love, promising that their hearts will beat for one and one only. In nature, the Malabar pied hornbills make good on such a promise. They're always seen in pairs. During the breeding season, the female bird is completely dependent on her male partner for food. If he fails to come back to the nest, there's a chance the female bird and their chicks would starve to death.

The bird has a casque on top of its bill, giving it a distinctive appearance. The species is common in India and Sri Lanka. They mainly feed on fruits, but also consume small birds and insects.

Here are some photos of the Malabar pied hornbills, caught by Sue Dall on a trip to Rebak Island, Malaysia.
