Birds thrive in all conditions. Be it the staggering heights of 18,000 feet to 21,000 feet; where Alpine Choughs nest; Lammergeiers soar and Snowcocks forage. They mesmerize you in all aspects. Thus to understand and gauge the fascinating features of avian fauna; one must be equipped with contrivances for recording.
You can be either a backyard bird watcher or an aged sectagenerian who prefers to watch birds from the balcony; an over enthusiastic 15 year old, ready to explore crevasse and rocky outcrops; regardless of what you do professionally, your thirst gives you the drive to evolve you from a start-up amature to hard-core.
It is not only the camera you should have with you, there are more gadgets and tools, which you must have to be a better birder.
