KENDRAPARA: With the onset of summer, the authorities of Bhitarkanika National Park have taken a number of measures to protect the animals and the birds from the scorching heat. Water holes have been dug up and curtains hung around pens of animals. Arrangements have also been made to ensure that there is adequate drinking water so that the animals do not suffer from dehydration. According to officials, animals get irritated when the temperature rises and it is necessary to keep them cool and provide them with a near-natural habitat.
