According to this article we will see less robins this year as their numbers are 27% lower than average. In fact robin numbers are at their lowest since 1997 according to a recent study. It is thought the decline is down to last years harsh winter which reduced the amount of food available for the birds. As the robin does not migrate in winter they tend to suffer more than other birds in freezing conditions. I have quite a few robins in my garden and have been keeping them well fed with seed, bread and kitchen scraps particularly during the recent snow when their food is harder to find.
