A quick visit to Maridalen today didn't reveal the Hawk Owl but it could very easily still be in the area.
The article that I was interviewed for last week has been published on an online newspaper, follow this link.
Just after reading the article a flock of 11 Greenfinches appeared in the garden. This is a garden record and it felt as though they had read the article and knew there was a good meal to be had in this particular garden!
PS, spot the misidentified bird in the pictures in the article.
