While 20x50 binoculars can be good for bird watching in some cases, they may not be the best choice for everyone. Higher magnification can make it more difficult to hold the binoculars steady which can be frustrating when trying to observe birds in flight. In addition, higher magnification can also narrow the field of view making it more difficult to track birds as they move. For these reasons, many bird watchers prefer binoculars with lower magnification such as 8-10 times.
