The lesser crested tern (Thalasseus bengalensis) is a bird species belonging to the tern family Sternidae. It is identified by the black cap of feathers present on its head and its long, orange bill. This tern is piscivorous in nature and feeds primarily on fish found in the middle layers of the ocean. It hunts these by taking part in fast-paced plunge-diving, fishing out prey with its sharp beak. They can often be seen foraging for food in huge flocks, consisting of other bird species as well.

These birds are usually found in large crowds among the sandy, rocky coastlines of Africa, Southeast Asia, Australia, and the Indian subcontinent. They are mostly migratory, with the Australian population remaining sedentary during the winter.

These birds are not particularly dangerous or aggressive. They rely on the sheer strength of their numbers to keep predators at bay, building their nests close together in the hopes that intruders would be too intimidated to approach. Being wild birds, it is still not a great idea to approach them as they might get alarmed and strike with their beaks and claws.

Would they make a good pet?

Being wild birds, it is not a good idea to keep them as pets. They are highly social birds and are comfortable in huge flocks which are not feasible to keep at home. They are also migratory, meaning they are non-residential birds and relocate during the winters.

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

Did you know...

Though these birds are very similar in appearance to the sandwich tern, Chinese tern, and elegant tern, there are subtle differences by which we can tell them apart.

The most obvious difference between these birds is in the bill, with the lesser crested tern having a bright orange bill, the sandwich tern having a black bill tipped with yellow and the Chinese tern having a black-tipped orange bill. The elegant tern also has an orange bill, though it is much more long and slender than the others.

This bird can also be told apart from the presence of its gray rump which is absent in the Chinese, elegant, and sandwich varieties.

It has two scientific names, the Sterna bengalensis and the Thalasseus bengalensis.

Do lesser crested terns migrate?

Yes, the lesser crested tern population is known to migrate during the winters. However, only the Middle Eastern and African population have been observed to move southwards during the cold, with the Australian colonies remaining sedentary all throughout the year. The migratory subspecies population winter in South Africa, returning home once the temperatures start to rise again. They mostly migrate after August once the breeding season is over.
