Since January 1979 the RSPB have asked the public to spend an hour counting the birds in their gardens (or nearby park). There is now over thirty five years of data and although not true science it does show how things have changed in that time. What it does show clearly is that there are twenty species that are commonly seen in gardens and are dependent to some extend on food supplied by people during the winter months. This series of posts takes a look at these twenty species in a little more detail.
