Swallow

One of my all time favourite birds, sadly, as with many other species, not as common as the were years ago. This one and the others, are nesting under the open roof areas at WWT Martin Mere information and café buildings.
The roof of the main building is a green one, or a sod roof as us commoners would call it. A very effective finish
I got a couple of in-flight shots either blurred or not very sharp, I have put the latter as an extra, but don't get excited. -:))
