Feeding garden birds is one of the most popular wildlife activities, but it carries welfare risks if done incorrectly. Understanding best practice helps maximise benefits and minimise harm.
Garden bird feeding done well provides genuine welfare benefits: improved survival through winter cold, better breeding season body condition, and supplemented nutrition during resource-poor periods. Done badly, it can transmit disease through contaminated feeders, attract predators, and create dependency that reduces natural foraging behaviour. Feeder hygiene is the most important welfare variable — dirty feeders harbour Salmonella, Trichomonas, and other pathogens that can cause mass mortality events in local bird populations. Feeders should be cleaned at least once a week with dilute disinfectant, moved regularly to prevent ground contamination, and stocked with appropriate species-specific foods. Placement matters too — cover for ambush predators should be avoided near feeders.
