This is the log book every falconer should use, as described in The Falconer's Apprentice. NOW IT RUNS ON YOUR COMPUTER. Track your hawk's progress by daily recording her weight, performance rating, amount of food and type of food eaten, and the daily low temperature. With this data, a hawk can be hunting sooner and kept in peak condition easier. Using a simple charting system, determine her flying weight and, more importantly, her true HUNTING weight. And the charts are drawn automatically! Complete with instructions and sample log book entries to get you started FAST. Works with any raptor and whether you use grams or ounces. Requires MS Excel 97& 5.0/95, or higher, or compatible software.
