The best binoculars for bird watching are the general-purpose, outdoor-wildlife binoculars known as safari binoculars. These binoculars are ideal for watching wildlife as well as for bird watching.
More powerful magnification is not always better because it narrows the field of view and makes locating the bird more difficult. The image is less bright, there is less depth of view and, unless the binoculars are attached to a tripod, it is difficult to hold them steady.
Since lower magnification means a wider field of view, many bird watchers prefer 8- to 10-times magnification. The wider the field of view, the more likely that the bird is immediately in view when the binoculars are raised. A wide field of vision is important in observing small, fast moving birds, especially in a forest or thick foliage.
