Birds are the most fascinating gift of the nature that have adorned the world with some inspirational shades, thereby magnifying the beauty a million times. Unlike the professional ornithologists, engaged in watching and studying birds for the scientific reasons, the act of bird watching is observing and studying birds merely for some recreational purpose. The birds are usually observed with the naked eyes or by the dint of a visual enhancement device, the most commonly used of which is a binocular.

A great section of the world's overall population is engaged in the hobby of bird watching or birding, although in India it is not too large as compared to the western world. The Indian bird lovers boast at the fact that there exist more than 1200 distinctive species of birds only in India, giving enough scopes for the birders from far and wide to study how they fly, what they feed on, the chirps of each species and there natural instincts.
Bird Watching Binocular
What is essentially necessary hereby is a good visual enhancement device - chiefly a binocular. This is the most significant component without which the hobby of watching birds will be of zero value. The most important fact regarding the issue is that a bird watching binocular is very much different from the a normal binocular and there are certain pivotal points to be seriously considered while buying a bird watching binocular. A good bird watching binocular should be an extremely powerful portable optical device that can give an eagle-eye view. The small binoculars are of no use in these cases. The big sizes yield great results. A minimum of 70 mm objective lens is, however, essential for the good transmission of light.

Another very significant criterion to be considered while buying a bird watching binocular is the kind of optics. Amongst the two different categories, viz. porro and roof prisms, it is advisable to opt for the phase-corrected roof prism binocular, although the porro prism binos are comparatively cheaper. This is due to the fact that the roof prisms binoculars are lighter and yield more detailed results.

Magnification and the objective lens size are the other vital parts of the story, when it comes to choosing bird watching binoculars. The optical power of the binoculars is defined as 10X40 or 8X36, where the first number indicates the number of times the original subject will be magnified or is closer, while the second number denotes the size of the objective lens. The bigger the size of the objective lens, the more light or image detail is going to be captured.

Another significant consideration while choosing a binocular for bird watching is the phase coating, which is basically a special treatment for the roof prism binoculars. The better the quality of the of the phase coating higher will be the resolution and the clarity of the image. With the good quality phase coating of the binoculars the bird watchers get quality range of close focus details along with the enhanced color resolution.
