Welcome to Expert Village.
My name is Wayne Peterson and I direct the Massachusetts AudubonSociety, Important Bird Areas Program for Massachusetts.
Today we're here at the DanielWebster Wildlife Sanctuary in Marshfield, Massachusetts we're going to be talking aboutthe equipment needed to get one started in birding.
Since arguably binoculars are oneof the most important pieces and perhaps one of the most potentially expensive equipmentaids that a beginning bird watcher wants to get.
It's very that you understand what someof the options are.
I have in my hands what was actually my first pair of binoculars,these were a 6 power binocular, they have individual eye piece focus.
In oder wordsinstead of being able to focus both lenses at once and they are of a model called PorroPrism.
Today I'm using a much more expensive and a much more sophisticated optic, whichis called a Roof Prism binocular that has a central focus mechanism so that both ofthe eye pieces are moving together and in fact all of the mechanized parts are insideas opposed to on the outside.
Now, as one can image over time as with cameras and withautomobiles, there are various degrees of expenditure and sophistication.
Some binocularscan be purchased as little as 150 to $200, middle priced binoculars can be in the middlehundreds of dollars and then for some of the high end binoculars one can be prepared tospend well over a thousand dollars to 12 to $1500.
Some of the considerations are brightness,how much illumination they're going to give the subject, what the minimum focal distanceis, in order words how close you can get to a subject and focus on it as oppose to lookingat something infinity, how quickly the focus mechanism works in order to get you from possiblysomething as close as a few feet to infinity.
If you're somebody like myself who wears eyeglasses, you need to think about something called eye relief so that when you put thebinoculars to your eyes, you have to remember they are not going to be right up againstyour eyes and as such there's a tunneling that can occur.
So that you want to make surethat the binocular that you're buying is one that has good eye relief.
Again, for eye glasswearers lots of binoculars have eye cups that can be pulled out.
If you are somebody thatdoesn't wear eye glasses and they can be turned in, again to maximize that eye relief phenomenonand put your eyes as close to the lens as possible.
