What is an Indian Roller?
The Indian Roller is a pretty bird belonging to the roller family of birds. Known by the name of ‘Blue Jay’ in former times, the brilliance of the color and beauty of the Indian Roller is captivating in every way.
Its English name has been inspired by the startling aerobatic display the bird performs in the breeding season. The Indian Roller is found in many regions of the world. The Indian Roller does not come under the list of migratory birds. Several states in India including Karnataka, Andhra Pradesh, Bihar and Orissa have chosen it as their state symbol.
One can identify the Indian Roller as a stocky bird that is fairly medium sized with an overall drab brown appearance whilst perched. The bird is approximately 26-27 cm long. It is important to remember that both male and female Indian Rollers look alike.
The Indian Roller acquires its name from the striking aerobatics it displays as an act of courtship.
Its crown and vent have a distinguished blue color. The dominance of the brown color is what helps to differentiate the Indian Roller from the European Roller which otherwise bears a close resemblance to it. In flight, the Indian Roller flaunts the brilliant combination of colors on its feathers. This beautiful bird has a mesmerizing sky blue colored tail with a hint of Prussian blue color. The feathers towards the centre have a dull green tint. Its throat and neck is noted to be purplish lilac in color with dash of white streaks.
The deep color of the grayish brown eyes of the Indian Roller compliments its beauty. Its blackish brown bill has a hooked tip.
You may often spot the Indian Roller bird perched or resting upon bare branches of trees. Sometimes these birds are also seen perched on wires in cities and urban areas.
It is quite rare for the Indian Roller to fly in groups. However they do have family groups and are observed to communicate with each other in ‘chack’ calls or sounds. The ‘chack’ sound is also associated with crows. Apart from this harsh call the Indian roller also produces metallic boink sounds.
An Indian Roller’s version of bathing involves direct dives into water, usually from a high altitude or height. Earlier this act of the Indian Roller was assumed as fishing.
Indian rollers are prey birds. They capture and feed upon their prey by descending to the ground. All kinds of insects, reptiles, moths and sometimes even frogs usually end up becoming the bird’s prey. It is also interesting to note how the feeding style and habitat of the Indian roller is similar to the Black Drongo. These birds are also observed to feed late in the evening time during the hot summer months.
In the cultivated areas of Southern India, these birds can be found in a ratio of approximately fifty birds per square kilometer.
The Indian roller usually prefers to alight on a 3-10 meter high perch. Unfortunately many rollers become victims of traffic collisions since they often tend to feed near roadsides taking aid of street lights at night.
The Indian roller is significant for its aerobatic display that has earned the bird its former English name. Whilst in a perched position, the Indian roller performs displays like wing drooping, bowing and tail fanning.
These birds prefer to build their nests in tree holes or places similar to it which may also include cavities in tall buildings. They use the remains or bits of wood to build their nests.
