Best equipment for bird watching:
. Choose your apparel and footwear in accordance with the season of the year and the conditions of the terrain;
. If rainfall is expected bring waterproof coat and footwear;
. Choose materials that do not make noise when you move;
. Choose discrete colors instead of bright colors (the latter betray your presence and may scare away the birds).

Other things you can/should do:
. Always carry water, fresh food and a garbage bag;
. During the summer the use of sunscreen and hat is indispensible;
. If rainfall is expected bring waterproof coat and footwear;
. If you are allergic to hay, pollen or any other agent, always carry an antihistamine with you;
. Do not pick fruits or any wild products without the authorization and advice of a specialized technician.
