Households are warned to change how they feed birds to prevent disease. They should not give birds two common foods to stop a deadly disease from spreading.

The Big Garden Birdwatch found that Greenfinches are declining. This species is now on the UK Red List due to a 67% decline.

Disease among birds is a major factor in their decline. Trichomonosis can spread via bird feeders and cause severe throat lesions.

Stop feeding birds peanuts and seeds from May to October.

Trichomonosis affects finches, pigeons, and doves, causing swallowing problems, lethargy, and weight loss.

The RSPB and scientists reviewed bird feeding methods. They urged households to stop using flat feeder tables to prevent disease.

This year, people are encouraged to change how they feed birds. They should stop feeding peanuts and seeds from May 1 to October 31.

Trichomonosis spreads in summer and autumn. Experts recommend feeding mealworms, fat balls, or suet to reduce disease risk.

Avoid using flat bird feeder tables.

The RSPB's chief executive said feeding birds can spread disease, affecting Greenfinches.

We're not asking people to stop feeding birds, just to feed them safely. Small changes can help birds' long-term health.

To reduce disease risk, clean your bird feeder weekly and move it to different spots to avoid contaminated food build-up.
