Keep your garden birds healthy

Greenfinches are in serious trouble, but together we can help by keeping feeding stations clean to stop disease spreading. This beautiful little bird was a common sight in gardens but has seen a dramatic decline of 63% since 1993. It has now been moved from the Birds of Conservation Concern’s green list to the red list. One of the reasons for the decline is because of a severe outbreak of the disease trichomonosis, which can be spread by contaminated food and drinking water. By keeping our feeders, bird tables and bird baths clean, we can help bring this colourful little character back to our gardens, as well as helping to keep our other garden birds, fit, healthy and disease free. Here’s how!

Cleaning your bird feeders

Put your gloves on and empty any old food from the feeders into a bin – do not reuse the food or compost it.


If possible, take the feeders apart to make them easier to clean 


With hot soapy water and a brush, scrub and clean the feeders, removing any old food or residue 


Rinse thoroughly with cold water, preferably outside 


Let it dry completely, again ideally outside 


Spray with the disinfectant, following the instructions.  


Rinse again and then let it dry out once more before refilling 

Cleaning your bird table


Put your rubber gloves on and remove any old food, by hand and with your scraper,and throw it away – do not reuse or compost.  


Fill your bucket with warm, soapy water and use the sponge to clean away any small bits of food and droppings.  


Rinse thoroughly with cold water, a hose pipe works well. 


Let it completely dry, before spraying it with the disinfectant, following the instructions.  


Rinse again and then let it completely dry before refilling.

Frequently asked questions


How often should I do it? - At least every few weeks, but ideally once a week if possible.  

How long will it take? - Unless you have lots of feeders, no more than 15 minutes 

Can I use bleach? - We recommend using an animal safe disinfectant but a weak solution of domestic bleach can be used as an alternative

Should I clean my bird bath? - Yes, cleaning any space where birds congregate will help them stay healthy. Ideally, clean water should be provided every day.  

What else can I do? 

  • Don’t overfill feeders – try and make sure they are being emptied every few days 
  • If possible, set up several different feeding stations to reduce the number of birds in one place.  
  • Move your feeders, to prevent the build up of bird food and droppings potentially contaminating the ground below.  
  • Avoid putting feeders under where birds roost, such as under trees, to avoid droppings. 
  •  If possible clean away any old food or droppings from beneath feeders too  

If I see a sick bird or birds what should I do? - If you think the birds have been affected by disease, it is best to stop feeding for at least two weeks and empty any bird baths. Only start feedings again if you are no longer seeing birds with any signs of disease 

Can I help the sick birds? -Treatment for wild birds is rarely an appropriate action and often it may be in the bird’s interests to be left in the wild. There is a lot more information here. 

Please report sickness or death of any garden wildlife to the Garden Wildlife Health (GWH) project.  This is a collaborative project between the Zoological Society of London (ZSL), the British Trust for Ornithology (BTO), Froglife and the Royal Society for the Protection of Birds (RSPB), that aims to monitor the health of, and identify disease threats to, British wildlife.
