Garden birds are struggling and will need plenty of help this winter.

That is the warning from Oxfordshire RSPB, who have urged people across the county to put out plenty of food for our feathered friends.

Starlings and sparrows are among the species on the critical list – described by the charity as of “high conservation concern” after a significant drop in numbers in the region.

And bird-lovers who want to know how best to care for birds over the winter months are invited to head along to the RSPB’s Feed the Birds Day tomorrow.

Hundreds of people are expected to take part in the event at the Oxford University Museum of Natural History.

Oxfordshire RSPB spokesman Andy Waters: “There are so many good reasons for Oxfordshire folk to enjoy feeding their garden birds.

“Some of our garden visitors are really struggling, such as starlings and house sparrows.

“Both of these birds are of high conservation concern or ‘red listed’ because their numbers have crashed.

“The RSPB is researching the problems, but we need people to help the birds by feeding them.”

Last year between 400 and 500 people visited the RSPB’s annual Feed the Birds event in Oxford’s Port Meadow.

Visitors spotted lapwings, little egrets, herons and golden plovers.

Mr Waters added: “Many of our garden birds are tiny and weigh as little as a coin.

“Birds like long tailed tits, wrens and coal tits really suffer during cold, frosty and wet weather, and many die.

“A little food and fresh water in your garden can make all the difference to them.

“And don’t forget that it’s great for you. Caring for garden wildlife and feeding birds is one of life’s great pleasures – it’s good for relaxing and our wellbeing.”

Staff and volunteers will be around between 10.30am and 3.30 pm to share ideas for attracting birds, bugs and animals closer to home.

Organiser Charlotte Kinnear said the event would have something for everyone.

She said: “This is the perfect time of year to set up your bird feeders and tables.

“Family events like this are an ideal way for children to enjoy and appreciate how amazing nature is.”

There will also be free wildlife activities on offer for children including crafts and a nature trail.

The museum, in Parks Road, has toilets and disabled access.
