Every morning, weather permitting, this woodpecker is up on the electric pole practising his drum rolls. Now, he can't be trying to find food because the pole is tarred and I wouldn't think many bugs and insects would tolerate that environment to make their home. So my theory is that it must be down to practice and enjoying the noise he creates, the noise is quite considerable and he must get quite a buzz from the tone and reverberation.
I've tried to get closer to him but as soon as I touch the back gate he's away, even if I go for a telephoto lens he's gone when I get back so he must be modest and camera shy, but being bright green and red I can't see where the shyness comes in. You have to work for your photographs with this woodpecker.
