Bird Watching Binoculars—What are They
Posted: Apr 13, 2016
If you are a bird watcher or know someone who is, then you know that finding a specific type of bird such as a yellow-bellied sapsucker is not always an easy task to complete. This is why these types of binoculars are made. They are binoculars of high quality and can make the difference between identifying a specific species or not. In addition to being of high quality there are also other exceptions that make them different from regular binoculars. Using bird watching binoculars instead of using a monocular or telescope helps you track a bird that is in flight much easier. Your brain is able to create a 3-D image of what you are seeing when you use both of your eyes at once instead of one eye, as you would with a telescope or monocular. It is critical that you have this type of depth perception in order to find your bird.
If you are new to bird watching and do not have your binoculars yet there are a few basic things that you should consider before buying them. As everyone knows when you are enjoying bird watching you will be spending a lot of time outdoors walking all over the landscape so you should make sure that your bird watching binoculars are weather resistant, durable, and lightweight. They should also be efficient even in the dim light of dusk or dawn and have quick focusing. You should look for ones that have a magnification of 7x or 8x and have an objective lens of forty millimeter. They should also have a central focus that can be turned smoothly by your index finger.
For your first pair of binoculars for bird watching it is best that you try them out in person instead of purchasing them online. By trying them out in person, you can see how they feel in your hands. You also want to make sure that you can see perfectly even you are wearing glasses. You also want to make sure that they can be adjusted easily. Buying them in a brick and mortar store will give you a chance to ask any questions you might have plus get some recommendations from the sales clerk.
The first pair of binoculars for bird watching was called Hunting Glasses and was produced in 1894 by the Zeiss Optical Works. This company used prisms to right the image but since the 1960’s most of these particular binoculars have switched to a newer form of prism called the roof prism. This is the preferred prism because of the straight line from your objective lens to your eyepiece. Binoculars for bird watching can range from a hundred dollars to as much as two thousand dollars.
