There are a lot of issues when it comes to choosing binoculars for bird watching. Golfers, hikers and bird watchers like to carry a monocular since it is only half the weight and size of a binocular and much easier to pack.
It is important to protect binoculars from dust, mist, rain, fog, moisture, sunrays, fire, and fingerprints. The same goes for hunting binoculars, and in both cases they should be lightweight, but probably with a smaller magnification, and larger objective. All light transmitting surfaces are covered with multi-coating to increase brightness.
So a pair of binoculars that has the number 7x30 stamped onto the casing is a binocular that will magnify any object to seven times its actual size, and has a lens size of 30mm. The objective lenses are located on the end of the binoculars furthest away from your eye when viewing. Binoculars with larger fields of view may work better, but the cost is considerably more.
You will find these to be quality binoculars that won't break should you drop them. The lower the light situation is, the more powerful night binocular you will need. You can easily calculate it by dividing the aperture by the magnification so that 7 x 50 binocular has an exit pupil of just over 7mm.
You can get a closer look of mountain ranges all over the world, so go and get a pair and get out there. All around the world people of all ages enjoy bird watching.
