Woodpecker pecking, an effective evolution?
My question is quite simple, were woodpeckers gifted with a positive form of evolution?


Though this has been addressed in comments, it's an opportunity to address a popular mind frame about evolution, that is anthropormorphizing it.

Evolution does not think or bestow in the sense that a philanthropist might. Evolution does not doom or treat unfairly as a dictator might. Evolution is merely the process of predominantly random changes in genetic material that result in a change in the expression of that genetic material. If it is a change that radically affects expression of a critical gene (say, that encodes the structure of hemoglobin), the organism experiences a lethal point mutation and ceases to exist. Evolution for that organism stops there; if death occurs before reproduction, the mutation is lost.

Evolution seems beneficial because the environment exerts selective pressures on life: if two animals (say, birds) in the same habitat (say, woodlands) eat the same food (say, larval insects), competition for resources exists, decreasing the numbers of both animals. However, if a mutation (say, a marginally different beak shape) allows even a slight chance that the animal will have a competitive advantage, it is kept in the population. A staggering number of mutations similarly either harmless or advantageous may eventually allow two animals to inhabit the same habitat without competition - a net gain for both animals.

But there's no gift involved. Just a mind-numbing number of non-lethal mutations over a mind-numbing number of years, under the influence of the selective pressures of the environment. You don't see all the mutations that were deleterious, resulting in countless deaths and dead ends because you are standing in one point in time, seeing what exists around you now. The woodpecker seems almost fantastical.


  Were [woodpeckers] given an improper and doomed form of evolution?


Evolution follows the same principles for all species: predominantly random mutations without rhyme or reason or form. If you want to speak of doomed animals, look to mankind's effects on the environment in the last 2000 years, or the last 20. When ecological niches are wiped out, that, not evolution, dooms an animal. The Monarch Butterfly is a poignant example of dooming a species by destroying it's habitat.

A great way the understand selective pressures of habitat is to read about marsupial evolution in Australia. The effect of ecological niches on evolution is very clear.
