Birds

So how does this project link up with birds? Simple. When a bird watcher spots a bird, and wants to record the sound, for any reason, the normal hand held tape recorder is usually to primitive to get a good quality recording. With the Parabolic sound reflector dish, the sound is amplified and so the quality of the recording is better. In practical applications, a simple lead from Parabolic reflector to tape recorder will greatly enhance the sound quality of the recording.

And as we conducted experiments on what type of dish is the best to use, as far as all purpose terrain was concerned, the bird watcher can now go and construct his own Parabolic sound reflector, using the guidelines as set in the section call AIM. This ability to manufacture ones own dish allows for the expense of either a new Parabolic Reflector or a top quality tape recorder, to be removed. Saving the watcher time. Also, since it is hand made, it adds a more personal touch to the bird watching experience.

Dish Delta proved to be the most versatile of all the dishes, when used to listen and record bird calls so it is recommended that if a bird watcher wishes to make a Parabolic Reflector dish, for the purpose of recording that dish Delta be made. This does require fibber glass use, so it is advisable that some experience in the use of fiber glass is known, as fiber glass can be dangerous. If that is the case, then a round sheet of Aluminum will make the perfect starting point for the construction of Beta. The second best dish in the field of bird watching recording. The following bird calls were recorded using Beta.

In short this project has set out to prove what dish is best suited for recording bird calls, and which is the most cost effective as far a performance is concerned.

Since this project is based on the applied uses of the Parabolic sound reflector to record, and receive sound, several attempts at bird watching were conducted. However, with a limited knowledge of birds and their species, the information on each bird is limited. However every attempt has been made to record the birds as accurately as possible.

All recordings were done using the Beta dish - the one constructed of Aluminum.
