Plump crested pigeons wander along the path picking at this and that, then take off to the sky with a noise that always reminds me of a squeaky wheel. I have just discovered that this characteristic noise is made air passing over a modified primary feather on the wing.

As they are a common visitor to my garden, I am surprised that I have not written of them before. I also notice there is currently in residence a new pair of birds feeding a young one. I have not identified them properly yet.
