Birding and Birdwatching 
Although the simple pleasure of birdwatching can be enjoyed with no equipment at all, once you want to see more rare or shy birds you will need to find a way to see birds without them seeing you. Some of the things you will need for more involved birdwatching include:
Binoculars
Bird
Hide
Digiscopy
Equipment
Finnstick
