This April, gardeners are urged to complete three vital tasks to protect birds visiting their gardens from diseases, particularly trichomonosis, which has significantly impacted populations like greenfinches, whose numbers have dropped by over 65% in the last 30 years. The Royal Society for the Protection of Birds (RSPB) has released guidance highlighting the importance of maintaining hygiene in bird feeders and baths. Gardeners should clean these items weekly to prevent disease transmission. Additionally, from May to October, it is advised to avoid placing seeds or peanuts in feeders, opting instead for mealworms or suet, as natural food sources are plentiful during this period. To further support the ecosystem, gardeners are encouraged to plant wildflowers, which attract beneficial insects and provide natural food for birds. The RSPB emphasizes that good hygiene practices, such as sweeping away old food and changing water daily, are essential for safeguarding bird health.
