Wild birds in gardens are susceptible to a variety of diseases, such as certain strains of salmonella in winter, and trichomoniasis in late summer and autumn.
And as the weather gets colder, larger numbers of birds visit gardens for our food supplies and fresh, unfrozen water, making it easier for disease to spread.
The diseases can spread especially quickly if droppings are allowed to mix with uneaten food.
In really cold snaps, birds’ resistance to illness becomes even lower making them particularly vulnerable, and disease can easily kill them.
But we believe that taking steps to keep feeding stations clean and healthy can be very effective in protecting garden birds.
It’s extremely rare for any bird diseases to pass to people or to pets like cats and dogs. Nevertheless, we recommend careful hand washing after cleaning feeders and water baths.
Choosing feeders and water baths that can be thoroughly cleaned in the first instance is vital.
Sick birds can be very obvious. Typical signs include lethargy and fluffed up plumage. In some diseases, there are additional symptoms like drooling saliva, regurgitating food, difficulty swallowing and laboured breathing. Some may have matted wet plumage around the face and beak or swelling in the neck.
RSPB wildlife adviser, Kirsi Peck, says, “As the weather gets colder, and our birds come into our gardens in bigger numbers, it is no surprise they can become vulnerable to diseases. It can be very distressing to find sick or dead birds, but there are things you can do to avoid it happening. We all think good hygiene is important in our homes and it need be no great effort to do the same in our garden. We’d urge everyone to clean their baths and feeders regularly to help keep garden bird infections to a minimum.”
