Roudybush, Inc. manufactures specialized bird foods. This manufacturing is a result of the research by an avian nutritionist, Tom Roudybush. During his 16 years of nutritional research in the Department of Avian Sciences at the University of California, Davis, Tom studied a variety of birds, including 10 years of research on the nutritional requirements of companion birds. Mr. Roudybush has generated most of the published nutritional research in pet birds, and the research flocks of Orange-winged Amazons at the University have been maintained on nothing but Roudybush pellets since 1981; no other population of psittacines has been maintained on a commercially available, formulated diet for such a long period of time.

In response to repeated requests from aviculturists hearing him lecture throughout the United States, Tom began manufacturing his diets in 1985, in a rented space of 800 square feet and with a few minor pieces of equipment. In 1986, Tom began manufacturing three Nectar Diets for wildlife rehabilitators that raise orphaned hummingbirds, or maintain non-releasable or overwintering adult hummingbirds. The diets were tested and developed through research using Anna's and Blue Throated Hummingbirds. A short time later, Roudybush also began to manufacture Squab Diet as a response to rehabilitators needing a diet that mimics the crop milk of Columbiformes.

Today, Roudybush inhabits a 32,000 square foot warehouse with state-of-the-art equipment that allows the company to maintain Tom's high quality standards. Tom continues to be involved in nutritional research, and is committed to learning more about the requirements of birds in captivity. This has lead to the manufacturing of diets for birds with special needs including; growing chicks, overweight birds, and birds with specialized nutritional needs due to certain disease process such as liver disease, kidney disease, intestinal tract diseases, and obesity.

When nutrition is important, Roudybush premium foods are second to none.
