Since the risk of disease transmission is related to the numbers of birds congregating together, one of the best things you can do is to use several feeding sites within your garden and to not just place all your feeders in one spot. This helps to disperse the feeding birds over a larger area and reduces the potential for disease build-up. It is also important to move your feeding sites periodically, especially those where you feed directly onto the ground. Allowing areas to ‘rest’ will help to reduce levels of contamination. Finally, think about where you position feeders in relation to other garden features. For example, it is best to avoid placing a bird table under a tree in which birds perch or roost, since it soon becomes heavily contaminated with droppings.
