The green woodpeckers are ground feeders.

"Habitat
the Green woodpecker can often be seen feeding from the ground,
heaths, downlands & pastures. It climbs up tree trunks and branches
and had become proficient at hanging from garden bird feeders in
search for a regular food source.
Behaviour
climbs, hangs, takes off & lands from vegetation, tables, feeders."

We get green woodpeckers feeding on our lawn quite regularly and
stopping off at the birdbath for a drink, but they're also fond of
flying up onto the side of a telegraph pole that's just behind our back
hedge and going round it in an upward spiral. I'm not sure if they're
investigating all the cracks and crevices for insects as if they think
it's just another tree, or if it's a convenient place to cackle from -
which they do, rather loudly.
