Garden bird feeding provides important welfare benefits for wild birds but also carries disease transmission risks - following evidence-based feeding practices maximises benefit and minimises harm.
Garden bird feeding welfare requires active management to deliver welfare benefits rather than causing harm. A dirty, overcrowded feeding station is a disease amplification site that causes net welfare harm by concentrating susceptible birds around pathogen sources. The welfare solution is not to stop feeding but to feed hygienically: clean feeders weekly with hot soapy water, dry thoroughly before refilling, and space multiple stations to reduce crowding. Regular rotation of feeding positions reduces pathogen accumulation in the soil below. The bird welfare benefit of supplementary feeding during harsh weather is significant - proactive hygiene management ensures this benefit is delivered without disease cost.
