There have been several comments about field documentation software and hardware. Let me mention one of my favorite toys, the iRiver digital recorder/player. It is the size of a double pack of gum, records and plays back CD quality stereo sound for hours, and easily uploads or downloads to a computer for sending, storage, or CD burning. Sound quality is adjustable through selective frequency adjustment as well as the digital sampling rate. A built in microphone is OK for voice recording, but a separate hand held stereo microphone is suggested for more noise free recording of bird calls in stereo. The sensitivity goes beyond your normal level of hearing, but may seem to have additional background noise because of the local planes, trains, and automobiles, plus the wind. For sending on slow dial up computer connections you may want to hold a sound snippet to 25 sec. or so for a couple of minutes of on-line download. You may Google out specs., reviews, or talk to iRiver by going on-line. Available new from e-bay for less than $100 depending upon the capacity of the model selected. I fabricated my own stereo microphone from easily available sensors, resistors, and some glued pieces of thin plywood. Be glad to share the circuit if you can use a soldering iron. You may contact me directly concerning any questions or comments.
