Inexperienced, blasé, cheeky or stupid take your pick. This pigeon couple have made their nest on the super slippy glass top of the upstairs, back window.
Two little white eggs are within the sticks and the pigeon sits happily not noticing the inextricable progress down the window towards the edge.
In order to halt the slipping we have propped the window open with a longer stick. All looking good today.
