Last time I saw a greenfinch in the garden – from 2014
Dear Readers, you may well know that Greenfinch and Chaffinch numbers in the UK have been in steady decline due to the advent of a disease called trichomonosis. A recent study by the British Trust for Ornithology (BTO), the Institute of Zoology and the RSPB has identified garden feeding stations as a source of infection, especially where large numbers of birds gather. However, it’s also recognised that gardens can be an important source of food for birds, especially during breeding season, so a number of recommendations have been made. uc
-  Both the RSPB and Vine House Farm (who support the BTO with sales of their mostly locally-grown bird seed) have stopped selling bird tables, which are seen as a major source of contamination. I won’t be using mine in the foreseeable future, both because of this, and because a largish animal has completely destroyed the one that I did have 🙂
- Change feeding spots – in the wild, food sources would come and go, so birds are used to this, and it prevents the build up of dropped food which can attract large numbers of birds
- Feed seasonally. Seeds and peanuts are favoured by the finches who are most impacted by trichmonosis, and they are most at risk from contracting the disease in the post-breeding season. So the advice is to provide seeds and peanuts from November to April, but to cease feeding these from May to October, and to instead provide small amounts of suet/mealworms – these will provide protein for the tits and other birds who are likely continuing to breed, but won’t encourage post-breeding finches to gather in large numbers.
- Provide ‘natural’ foods such as teasel, thistle and other seed plants – these will still attract finches, but not in such close proximity or such large numbers
- If you or a neighbour has a pond with a shallow area where birds can drink/bathe, there is no need to provide additional water unless the water is frozen or has dried out. Where you do provide a bird bath, it should be refilled daily, and washed weekly.
- And of course, the usual advice about cleaning feeders weekly applies.
I know that there are broader questions about the benefits or otherwise of feeding wild birds – research on the subject is continuing to develop, and I will post here about anything that I find. This is a nuanced and emotive subject – so much depends on the location, the birds who are visiting, their numbers and what food is being provided. But I know we all want the best for our feathered friends, so let’s see how the discussion develops.
