Woodpecker is one of the most interesting types of birds. There are over 200 species of woodpeckers that can be found all around the globe except in Australia, New Zealand and Madagascar. Woodpeckers live in forests, backyards and various other types of habitat where trees are available. Several species of woodpeckers are endangered or already extinct due to habitat loss and increased urbanization. Also, chemical pollution and usage of aggressive pesticides negatively affects survival of woodpeckers in the wild because it induces destruction of the eggs.
