Garden bird feeding supports wildlife welfare by supplementing natural food sources, particularly in winter, but requires hygienic practices to avoid the disease transmission risks that can harm the birds being helped.
Garden bird feeding is one of the most accessible wildlife welfare actions available to people with outdoor space. Done well, it provides genuine welfare benefits by reducing starvation risk during food scarcity periods. Done poorly, it can transmit disease between birds at concentrations higher than natural foraging creates. The welfare calculus strongly favours feeding when hygienic practices are maintained, feeders are sited appropriately to reduce predation risk, and a diversity of food types is offered to support different species. Feeding is a supplement to, not a substitute for, the habitat quality improvements that deliver long-term wildlife welfare benefits.
