     Why do so many of us watch birds with great interest? Perhaps the easiest answer is that birds seem

to be the commonest, most attractive and easiest observed wildlife around us. No matter where you are,

at home, on a mountain-top, in mid-ocean or deep in a city, there are birds around for you to watch.

     When you go birdwatching, you should always make sure that your clothes are suitable for the weather and for the habitat you are visiting. As a general rule, it is better to pack a little too much clothing than risk getting cold and wet.  In really hot weather, a hat of some sort is sensible. For cooler weather, a practical outfit would be jeans, a roll-neck sweater.

     Don't worry about the equipment while birdwatching. It is perfectly possible to see and enjoy birds

without any special equipment, but a whole new world opens up to you once you have your first binoculars. Distant birds stop being little dots against the sky or water, and take on shapes and colours, and

feathers of bird will have a real beauty of their own.  Binoculars allow you to identify birds correctly, and

give you a wonderful chance to spy on them going about their daily lives. However, never look directly at

the sun using binocular, because direct sunlight can hurt the eye.

     Using binoculars is one way to bring birds closer to you, but another way of improving your

birdwatching is to get nearer to them. If wild creatures don't know you are close to them, they will

continue to behave naturally, and perhaps pass close by you. Fortunately, birds have no sense of

smell-so we don't have to worry about the wind blowing our scent to them and frightening them.  

But all birds have good eyesight, much better than ours.  Birds also have good hearing: their lives and

their ability to find food depend on these senses.

     So what does the birdwatcher need to do? Always move about quietly, do not give the birds

advance warning of your arrival or they will move away. Do your best to avoid sudden movement.

Always remember to put the birds' interests first. When you have finished looking, don't just stand up

and walk away, scaring birds in all directions.
