This little fellow is a house sparrow (Passer domesticus) a bird that occurs in most of Europe and much of Asia and has been introduced to many countries around the world.
Here in England when I was a boy we would have thought just a very common small bird. Sadly today as I write this they are by no means as common as they once were, as a child I recall seeing hundreds of them perched on telephone wires. These days the most I would see at any one time is perhaps a dozen (12). In Britain it is believed that over the last 20-30 years numbers of house sparrows have fallen by around 60-65%.
We can all do a little bit to help birds like the above male house sparrow, by perhaps having a bird table with food, hanging a feeder in the garden (as above), maybe putting a bird box or even several in our gardens. Think how dull our world would be without them.
