Understanding how to select the best binoculars for bird watching comes down to some extent to a set of numbers. These numbers refer to the optical qualities of the binoculars and you'll find that the best binoculars for bird watching are usually not the very same as the very best binoculars for astronomy or boating or shooting. Let's look closely at the numbers and what to seek out in birding binoculars.
1) Power. It's sometimes a temptation to on-line and buy the most powerful binoculars for birding which you can locate. Don't! Knowledgeable birders typically use binoculars that are 7, 8, 9, or 10 power. A smaller amount than this and they don't actually help a great deal. Binoculars over ten power have two difficulties. First, they're hard to hold still. Greater magnification equals a lot more jiggle. Second, the field of view for high powered binoculars is smaller. This makes it hard to find the bird, specifically when it might be in flight.
2) Aperture. This is where the light enters the binoculars and is the second number, for instance, in 7 x 50, 50 will be the size with the front opening where light enters. Try to find a number in between 30 and 50. Compact binoculars might have a number around 20 to 25, possibly less. That's ok for compacts, but they won't have the same general performance as a bigger set. Additional light will mean a sharper and brighter image, particularly just after sunrise or near sunset. Binoculars larger than fifty are going to become heavy and you'll get tired of carrying them around your neck. Find a pair somewhere close to 8 x 40 or so and you will discover the best binoculars for bird watching.
3) Eye relief. That is how far from your eyes the lenses will need to be. This number is particularly critical for those who wear eyeglasses. In the event you wear glasses, a minimum of 14mm of eye relief will probably be necessary to allow for them. Actually, this isn't much of an problem with modern binoculars as most have a good amount of eye relief. If thinking of buying old, estate sale binoculars, take this into consideration.
The fantastic thing about the best binoculars for bird watching is that they are good all around binoculars for other applications. The very best birding binoculars are usually not too large, not too small and not too powerful. Later, you may wish to add a stronger spotting scope to your equipment for nest watching, etc., but starting with a great set of bird watching binoculars will get you headed in the right direction.
