Feeding wild birds heightens the risk of disease transmission at feeding locations. When we offer supplementary food, such as seeds or meat scraps, this attracts birds of many different species in a combination and number that would not happen in nature. They may carry deadly diseases, such as the H5N1 virus, and potentially spread them to other birds. This can create a transmission hotspot right on our back deck.
