For the last couple of years we've seen more and more birds 'discovering' that the red hot pokers in the garden at RHS Rosemoor are a good source of nectar. Last year we saw mostly greattits doing this, but as you can see this year the greater spotted woodpeckers are getting in on the act as well!
It will be interesting to see if this becomes 'learned behaviour', as I'm sure that when the young birds leave the nest their parents will introduce them to this rich energy source.
