With the light behind them it was almost impossible to photograph them, but I gave it a go and although not very clear, here's the proof that these birds really do live wild at the bottom of our garden!
In the first picture you can just about make out the bird sitting in the far side of the tree near the centre of the photograph.
When they fly, they are really obvious as these brightly coloured flashes cross your field of view. But sitting in the tree they blend in rather too well at times! There are at least two others in this picture but I can't see them!
