The bird was pretty mobile and didn't come close too often but when it did the advantage of this site was evident - rather than my usual experience of looking up it was around eye level. It's funny, looking at these twigs and branches the broken ends, etc make them look like props, but all were firmly attached to trees. I have to be honest there has been a bit of twig removal in some of these shots, although only to the fairly basic extent that lightroom can achieve.
Rather than spend the whole morning on the ww I went to look at my favourite hawthorn tree, to see if I could add to the 4 species I've seen nesting there before. Sadly no sign of anything using the holes this time. However a few trees along a treecreeper was repeatedly working up and down (well actually up and up) an oak, progressively adding to it's beakful of insects. I tried moving closer and it basically ignored me so I was quite pleased with the shots I got in the end, even with the green cast from the leaf canopy.
