Greywood Manor Teas

"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, Natural Pet Animal Hospital

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.

And to echo Dr. Becker’s comments above, when using green, black, or white teas, always be sure it’s organic and decaffeinated for your birds. We have been using teas for many, many years with wonderful results and we hope you decide to try them with your own birds.

With the help of avian veterinarian Karen Becker, DVM, NMD, Greywood Manor has developed several different blends of teas for birds, reptiles, small mammals, lemurs, 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.

We offer tea blends that offer a host of benefits based on carefully formulated mixes. All teas contain loose leaf, human grade ingredients with organic ingredients. You can read more via our Tea Guide here.

 

Brewing Hints:

Tea is Served!

When first provided with tea, some birds will be suspicious so it is important to note that some birds may need to start out with weak tea and increase the concentration as they become familiar with it over time. You should always brew tea in hot, but not boiling, water to maximize steeping ability. It is also recommended to make use of a stainless steel mesh tea steeper when brewing tea and to always remove it before serving. It is not recommended to completely replace water with tea, however, so as to avoid dehydration if the bird chooses not to readily accept the tea provided.

If your bird is still suspicious, there are other ways to glean the benefits of tea. When cooking for your bird, it is quite easy to substitute tea for water when preparing beans, rice, pasta and other items that are prepared in hot water. Baking is another opportunity to incorporate tea by replacing water with tea in the recipe for bird bread, muffins or another concoction your birds prefer. Offering certain teas without steeping them is another option, as small birds love to eat flowers, for example, within their dry food mix. We also roll items like chamomile or calendula flowers into our daily fresh fruit mixture for our birds to increase and diversify the nutritional content of every bite.

The use of tea is yet one more way to incorporate additional items to the diet and increase the amount of vitamins and minerals in your daily regimen. Teas can also serve as a great enrichment tool, using a different kind each day to keep things interesting. The many methods discussed here will hopefully allow you to provide more diversity in your birds’ diets and help your birds to not just survive, but thrive.
