I'm really pleased it looks like our green woodpecker might be nesting in our poplar tree again this year. He/she's just scouting around at the moment I think but last year raised three chicks. I don't know much about woodpeckers but do they use the same nest year after year? It was great watching the young birds leave the nest last year. They just took a day of teetering and flapping in the treetops in our garden before flying away for good.
