Great Spotted Woodpecker
27th May 2006
The great spotted woodpecker is similar to a blackbird in size and its mainly black and white plumage has given it the other name of pied woodpecker. It’s dirty white under parts contrast with the extensive area of crimson feathers under its short and very stiff tail. On its shoulders it has two large white patches with small white spots on the folded wings. The shoulder marks show as oval patches in the birds undulating flight. At close quarters the adult male can easily be identified as it has a crimson patch of feathers on the back of the head which is absent in the female. Juvenile birds have a red centre to their crown. The stiff tail is used to support the bird when on the side of a tree or in other situations such as at a garden feeder. Outside the breeding season great spotted woodpeckers are normally solitary and when danger threatens they will spiral up a tree trunk and often “freeze” on the side facing away from danger. The call note of the bird is a sharp and loud “kek kek” that can be heard at any time of the year and is often the only sign of the bird as they are fairly secretive. In late winter and early spring the so called “song” is made by drumming with its beak on a branch. The short bursts of drumming last around five seconds and accelerate before fading away at the end. Of all the European woodpeckers the great spotted take the highest proportion of vegetable food in its diet. A traditional food is the seeds of pine trees which they extract from the cones by wedging them in crevices in tree trunks and hammering out the kernels with their strong beaks. Peanuts look a little like the kernels and so the birds have very muck taken to peanut holders, particularly as more and more people are putting them out all year round. At the end of the breeding season the juvenile woodpeckers are brought into some gardens and it is amusing seeing them being taught how to cope with the wire mesh of feeders. One aspect of the birds behaviour is cause for concern as their liking for succulent small items of food from holes in trees has made some of them take a liking to young birds in nest boxes. If the woodpecker cannot reach the chicks through the normal entrance hole they will just enlarge it until they can get to the “food”.
Metal plates with holes can help but a really determined bird seems to know exactly where the chicks are in the nest box and simply hammers its way inside. Using tougher wood at least an inch thick will help. Attacks on sand martin colonies can be devastating as the woodpeckers have no problem in excavating the sand. Small colonies of starlings are also the target with the young taken and eaten when they are three quarters grown. Great spotted woodpeckers are well scattered throughout the Highlands although absent from large areas where there are few trees such as parts of the flow country of Caithness and Sutherland. As would be expected they are commonest in the extensive deciduous woodland either side of the Great Glen but there are even a few breeding records from the north coast. In many parts of the Highlands the easiest way to see these attractive woodpeckers is to simply put up a couple of peanut holders and they will visit them virtually at any time of the year even when the feeders are quite close to the house.
