Professor Harrison of Ireland wrote a computer program to pair budgerigars. A computer allows pedigrees and other records to be maintained to a superlative degree. Data base programs will print out detailed pedigrees. The aviculturist who can view at a glance a dozen generations of ancestors of any pair of birds will surely be better prepared to develop superior stock. A potential purchaser will be willing to pay more for young birds that are sold with detailed documentation.
Information is power, the power to precisely improve the quality of our birds.
