Twin Beaks® Aviary was born from Cathy DeHaan's deep-seated belief that avian health begins with nature's own chemistry. A pioneer in the field of avian self-selection, Cathy has dedicated her career to studying the symbiotic relationship between birds and botanicals.

Her work is defined by a commitment to 'Species-Appropriate Nutrition', a philosophy that respects the bird's innate wisdom to seek out specific nutrients. Through her decades of research and aviary management, Cathy has developed a standard of purity and efficacy that has made Twin Beaks® the trusted choice for veterinarians and serious enthusiasts worldwide.

Before natural avian care was a retail category, Twin Beaks® Aviary was defining it.

Established in 1989, our formulations, including the original Herb Salad™ Avian Blend and Pure, Calcium Supplement Hatched!™ Crushed Eggshell, were born from decades of direct aviary observation and botanical research. We didn't join the movement; we started it.
