"I approve and encourage the use of herbal and/or decaffeinated teas for birds. When offered correctly and appropriately, tea can enhance a bird's life by enriching her life experience and introducing additional nutrition. I often recommend various teas to clients. Their use supports many treatment protocols and aid in healing and mental health.” ...Karen Becker, DVM, NMD
Many have made claims and hid behind hand-picked research that teas are bad for birds. In science, for every claim there is a counter-claim and so forth. Without question, tea has stood the test of time and has had profound impacts on the health of many. It is no secret that there is little research on birds but, like most other research, the use of studies on other animals and humans give us an idea as to how the compounds in teas work. Below is a list of sources, most peer-reviewed scientific journals that continue to expose the benefits of teas. This list barely scrapes the surface of what we know but it is certainly a good place to start to show how the many different types of teas are beneficial. We have been using teas for many, many years with wonderful results and we hope you decide to try them with your own birds. - Jason Crean MA, MS

With the help of avian veterinarian Karen Becker, DVM, NMD, Greywood Manor has developed several different blends of teas for birds, reptiles, small mammals, rodents, guinea pigs, goats, sheep, chickens and other species. Though water quality is important for our avian companions, what birds drink in the wild is far from sterile. It is commonly known that many species of birds visit water sources like tree hollows in which plant components leach their tannins and other compounds and minerals. And many of us have seen wild birds drinking from “dirty” puddles and other water sources that are brewing with fallen leaves. These teas are just another way to bring a very vital part of nature into your pet's lives. - Jason Crean MA, MS
