A kind reader pointed out that my setting had been set so that only those with an google account could comment. I have now changed this to allow hopefully anyone to comment so please feel free.
I would also love more subscribers as I only have three! I am very grateful to my three subscribers (one of which is David Lindo. Please have a look at his blog by the way. It is brilliant for all us urban types who also like dabbling with some bird and wildlife watching in an urban habitat).
