The Andaman Islands forms an archipelago of 325 islands in the Bay of Bengal between India to the west, and Myanmar to the north and east, and is a sovereign territory of India. The islands form a land mass of 6,400 square kilometers, with the Andaman Sea to the east and the Bay of Bengal to the west. The natural vegetation of the Andamans is tropical forest with mangroves along its coastlines. The Andaman rainforests are similar in composition to those of the west coast of Myanmar and thousands of years ago the present-day Andaman Islands were thought to be attached to mainland western Myanmar. The Andaman climate is typical of tropical islands of a similar latitude, namely warm, humid but with sea-breezes. Rainfall is irregular except during the monsoons of July to September. The Andaman coastlines are outstandingly beautiful as well as relatively undisturbed, and coupled with the fact that its avifauna is extremely rich with a particularly high degree of endemism, 22 species in total, these islands have become an especially attractive destination to the birdwatcher.
