Great Spots are found widely throughout Britain, they are common in woodland and readily visit garden feeders. Lesser Spots are scarce and rarely seen. So you are much more likely to see a Great Spot than a Lesser Spot.
You can easily tell the difference………..
Great Spots are quite small birds the size of a Starling, a bit smaller than a Blackbird.
They have a crimson patch under the tail, a black back with a clearly defined white patch on each 'shoulder' and spotted wings.
Males have a red patch on the back of the head, females do not.
Young Great Spots have a red crown which can cause confusion with male Lesser Spots. See our photo of a male Great Spot with its youngster
Lesser Spots are tiny, the size of a Sparrow or Chaffinch and are only a quarter of the weight of a Great Spot
There is no red under the tail and the back and wings have black and white bars/stripes.
Males have red on the top of the head, females do not.
