East Yorkshire’s Greenfinch numbers 'in decline'

Finches in East Yorkshire have been threatened by trichomonosis, a deadly disease causing a decline in numbers, according to the RSPB.

Greenfinches, Chaffinches and Goldfinches have all been infected by the microscopic tricho-monad parasite.

It infects the bird's throat, preventing it from swallowing, and has caused the greenfinch populations to decline by up to a third in some areas.

The RSPB said people should be aware of ill birds in their gardens.

Dawn McKay from the charity said: "One of the things we're asking people to do is just keep an eye out on your greenfinch populations.

"If you see any birds that look listless, that have damp or wet plumage around their face and bill, then you may have a problem.

"The best thing to do is just make sure that you keep your feeders all good and clean and change the water in the bird baths and the bird tables.

"Just keep an eye on the hygiene out there."

She added that if an unwell finch is spotted in the garden, people should stop feeding the birds until there are no sick birds in the area to prevent the disease from spreading.
