16. WILDLIFE SOUND RECORDING by Ron Allen Often on Club meetings I am asked about tape recording and sometimes what one should purchase. Sound recorders, like cameras, start with those you simply point and switch on, to those with as many buttons and dials as you care to choose. Like all field equipment, the sound recorder must be robust, reliable and preferably cheap since like most other things it is bound to get dropped in a puddle or over a cliff at some time in its life. Lightness is particu- larly important if, like me, you tend to carry camera and binoculars as well. Recorders come in two types: "reel to reel" with two circular spools of tape and "cassette" recorders that take the "compact cassette". Both are satisfactory and come in all sizes from that of a transistor radio to table top models, mono and stereo. Reel to reel recorders small enough to be really portable are few in number. The small reel size of these limits the recording time but the sound quality is good. Cassette recorders are gaining in popu- larity all the time and it is this type that I have. Before you buy one it might be wise to consider the following points if you want it primarily for outside recording. Many cassette recorders are mains or battery. While these are convenient indoors, the extra weight of the transformer is considerable. I have a separate transformer that stays strictly at home.
