I have not seen the pigeon(s), at work, for some time.
What I have seen is a Magpie. Do Magpies chase off pigeons?
I have also started wondering if it is a mutant Magpie.
You see, at the same time a Wagtail has started flying around the place.
Have you ever noticed that with the exception of the size, Wagtails and Magpies look very much alike?
And, I have never seem them both at the same time!!!
